Prompted to install Webex Meetings multiple times

If you clear your cookies in Google Chrome, Mozilla Firefox, or Safari, you may see the install screen again the next time you join a meeting from your web browser, even if you already installed the desktop app. If you click the install file, you launch the desktop app.

Recording playback on mobile devices

You cannot play back a network-based recording on a mobile device.

Default meeting templates

If the First attendee to join will be presenter option is enabled in Site Administration, this option is enabled by default in the meeting scheduler on your Webex site. It is also enabled in the default meeting template that you use in Productivity Tools for scheduling Webex meetings with Microsoft Outlook. Custom meeting templates that have been created by users are not impacted. If a host schedules meetings using custom templates and wants to have the first attendee to join the meetings automatically become the presenter, the host must manually enable the setting in the custom templates.

Network-based recordings

Network-based recordings require a minimum bandwidth of 2.0 Mbps to play smoothly; otherwise, pausing might occur.

MP4 Playback in non-Webex Meetings video meetings not supported for the Webex Meetings desktop app for Linux

Linux users on the Webex Meetings desktop app can't start or join a non-Webex video meeting that has enabled MP4 playback. They receive a warning message indicating their operating system is not supported for this meeting, because Linux only supports ARF recording format.


We recommend that Linux users use the Webex Meetings web app for MP4 playback support in non-Webex video meetings.

Active audio-only meetings recycled

Audio-only meetings are recycled according to the 90-day meetings recycle period, or 180-day recurring meetings recycle period, even if the meetings were hosted or joined within that time.

Personal Rooms

Windows 8 phones and the Webex Meetings desktop app for Linux—You can't start or host a meeting in your Personal Room using a Windows Phone 8 device or the Webex Meetings desktop app for Linux.


We recommend that Linux users use the Webex Meetings web app to start or host meetings from their Personal Rooms.

Personal Room lobby—Users of the following devices or applications cannot wait in the lobby while a Personal Room is locked: Webex Meetings desktop app for Linux, TelePresence devices, and Windows Phone 8 devices. In addition users who join only the audio portion of the meeting cannot wait in the lobby while a Personal Room is locked. These users will receive a message that the room is locked, and will not be able to join until the room is unlocked.


We recommend that Linux users use the Webex Meetings web app to wait in a lobby while a Personal Room is locked.

For more issues that affect Personal Rooms and Webex Meetings video, see Cross-platform Features and Known Issues.

Webex Meetings web app

Video Limitation

VoIP is not supported when the host account has Webex Meetings video conferencing disabled.

Slow join times after a major upgrade

After a major Webex Meetings Suite upgrade containing more new features than a regular service pack release, you may encounter a long load time, as more files have to be downloaded and installed. Loading times depend on your network's bandwidth and the amount of traffic at the time of the download. In general, load times can range from 20 seconds to 3 minutes or more.

One meeting at a time

Mac users can join only one meeting at the same time.

In-meeting experience

  • When the language is set to Korean, the meeting topic might sometimes show incorrect characters.

  • The video settings button does not appear for the Participants panel on a Mac when a participant is viewing shared content in full-screen mode.

  • Keyboard navigation and screen reader support:

    • Video thumbnail items in the Participant panel do not support navigation using the Tab key.

    • Some items in file sharing and in the Polling panel don't support navigation using the Tab key.

    • Items within the video full-screen view don't support navigation using the Tab key.

    • Elements inside the video user interface don't support screen readers.

    • Video thumbnail items don't support screen readers.

    • The participant list within the Participant panel doesn't support screen readers.

    • Some elements for file sharing and in the Polling panel don't support screen readers.

  • The Pan tool is not available when viewing a file that is shared using file sharing.

  • The new interface is not available for Linux users.

  • On Mac, when the presenter annotates during application sharing or screen sharing (formerly called desktop sharing) and takes notes or creates a poll, the Notes and Poll information cannot be saved.

  • On Mac, when using annotation during sharing, if user moves from tab view to full-screen view, the annotation option that as last used is not remembered.

  • On some Windows machines as well as on Linux machines, if attendee screen saver comes on and then the presenter starts file sharing, the screen saver automatically quits.

  • Some custom Quick Start templates, created using older releases of Webex Meetings, may not work after upgrading to this release.

  • In a few cases, uploading a very large Microsoft PowerPoint file to share in the meeting may cause the meeting to get disconnected for the presenter.

Initials in avatars

The first letter of a user's first name and the first letter of the user's last name are used in avatars when there is no image available. Users with second names comprised of more than one word will not be displayed correctly as three letters, for example, "Mary Van Buren" and "Robert Smith Jr." will display as "MB" and "RJ" respectively.

Anyone can share feature

  • The Anyone Can Share feature is not available for Linux users on the Webex Meetings desktop app. It is also not available for mobile users who are using earlier versions of the Webex Meetings mobile app. This feature will be supported in the Webex Meetings app version 6.6 or later for iPhone and iPad and version 6.5 or later for Android devices. Mobile users who have earlier versions of the application can still be made presenters by passing the presenter role to them only if the mobile app has presenter capabilities.


    We recommend that Linux users use the Webex Meetings web app to access the Anyone Can Share feature.

  • If a host starts a meeting on a desktop and then disables the Anyone Can Share feature while in a meeting, participants in that meeting who are using earlier versions of the Webex Meetings app for iPhone, iPad, and Android devices will still be able to share.

  • Users of the Webex Meetings mobile app will not be able to disable the Anyone Can Share feature within a meeting, but will follow the site administration settings for that feature.

Host role taken over by a joining alternate host

In some circumstances, the host role may be taken over by an alternate host when joining a meeting or session, even if the host has already joined. If this occurs, we recommend the alternate host assigns the host role back to the host.

Links generated by Webex Meetings and Webex recording services

As part of our continuing updates to improve security, Cisco is making changes to improve the management of cryptographic keys that are used to generate URLs used in the Webex Meetings Suite and Webex recording services. As a result, existing links that were generated by those services have been updated, and sometimes, users may need to request new links. More information can be found here:

Multi-monitor support in Windows 10

Shared content may get cut off or display partially when sharing from a secondary screen that has a higher resolution than your primary screen. To remedy this, we recommend that you set your largest display to be your main display in your Windows display settings.

Shared documents display quality

Webex Meetings uses a printer driver interface to import documents that are not natively supported. The presentation quality of documents shared in Print Driver mode, such as Microsoft Word, Excel, and Adobe PDF documents, cannot be better than a hard-copy printout of the same document printed by a physical printer. This issue is pronounced when these documents contain images of text.

Cropped, cut off, or misplaced drawing objects

Drawing objects partially or wholly outside the 15-bit twips (32768 x 32768 twips = 22.75 x 22.75 inches) coordinate range are not displayed, cut off or misplaced. This includes regular PD drawing objects, images, UCF objects, and annotations. The actual size on pixels depends on the screen resolution and screen size.

To avoid this issue, we recommend you resize large documents to fit within the above coordinate range.

Microsoft Office 2013 and later support

  • If you have Microsoft Office 2013 or later installed, the following features are not supported when sharing PowerPoint files:

    • Animations and transitions

    • Embedded video or audio files

    • UCF Toolkit

  • If you have customized your Info Tab, some custom elements may not be supported. We recommend that you validate it to make sure it continues to display properly in a Webex meeting.

  • In a few cases, the following problems may occur:

    • Text and fill colors may be slightly different from the actual colors in a slide.

    • Some graphic elements may be missing from a slide.

    • Fonts may appear blurry on a slide or may be different from the original.

    • The size of shapes may be different from the original.

  • If an object in a PowerPoint presentation does not display correctly in edit mode, it is automatically removed in Slide Show view; however, the object may continue to display when the file is shared in a Webex meeting.

  • You cannot share password-protected PowerPoint 2013 files using the file sharing feature. Use the application sharing or desktop sharing features instead.

  • You cannot share Excel 2013 files on Windows 8 using the file sharing feature. Use the application sharing or screen sharing (formerly called "desktop sharing") features instead.

  • You cannot share Word 2013 (64-bit) documents on Windows 8 (64-bit) using the file sharing feature. Use the application sharing or screen sharing features instead.

Tagging internal participants

Tags for internal participants do not appear in the following cases:

  • When the participant joins from mobile device

  • When a participant using One-Touch TelePresence Plus is not using SAML single sign-on

  • In Personal Conference meetings

File sharing

If you are a host using Windows and do not have a universal printer driver that is installed on your system, you will not be able to share any file types except Microsoft PowerPoint files during file sharing. In this case, the system will provide an option to move to application sharing instead of file sharing or to install a universal printer driver before you proceed. (Windows 7 systems come pre-installed with a universal printer driver.)

Streaming media sharing

Attendee video resolution is optimized to 480p. Video files with higher resolution are resized to fit (640 X 480) resolution. The following media file formats are currently supported: WMV, WMA, WAV, MP3, ASF, AVI, MPG, MPEG, FLV, F4V, and MP4.

Recommended System requirements for video file sharing on Presenter side:

  • Core2-Duo E6750 @ 2.66GHz for VGA file is required

  • AMD 9650 2.3GHz (4 core) 8GB is preferred

  • Intel® Core™ 2 Duo -E7400 2.8GHz 2.79GHz is preferred

Audio switching to internal speakers when file sharing

If you are using an external audio device such as headphone or external speakers, sharing a file with sound, such as a WRF file, forces the Webex Meetings application to switch to the internal speakers, even if you select an external source in the Webex Meetings sound settings. The application returns to the external device once you stop sharing the file.

Unable to join meeting

Linux/Unix users might not able to join the meeting if NTLM authentication is enabled with ISA proxy. We recommend that Linux users use the Webex Meetings web app as a workaround.

Viewing Office 2007 and later documents

Attendees who join a meeting from the Webex Meetings desktop app for Linux/Unix may have display issues when the presenter shares a Microsoft Office 2007 and later document. For example, some animations and pictures may not be displayed or become distorted. As a workaround, we recommend that attendees use the Webex Meetings web app.

Microsoft Office PowerPoint

In Microsoft PowerPoint 2007 and later, text that is copied from a web page and pasted into the notes panel may not render properly. A workaround is to copy the text into Microsoft Word or Microsoft Notepad, then copy the text again from that editor in the notes panel.

Importing contacts into Microsoft Outlook 2010

Importing your company address book into your Webex Meetings contacts is not supported with Microsoft Outlook 2010 64-bit.

Closing a meeting

In Internet Explorer 7, if there are multiple tabs open in the browser, and the Webex Meetings "Meeting in Progress" page is not the tab in the foreground, the meeting manager cannot be closed. The reason is that the "Close meeting" confirmation dialog box becomes hidden if another tab is on top of the Webex Meetings page.

Full-screen video view

When the presenter switches to full-screen video view while sharing his or her screen (formerly called "desktop sharing"), an application, or a document, sharing is paused on the attendee side (the last-shared screen freezes) if they have only one monitor. When the presenter exits full-screen video view, sharing automatically resumes.

Attendees stay in full-screen video view when the presenter stops sharing and automatically exits full-screen video view when the presenter starts sharing again.

If the presenter has two or more monitors, they can easily share content on one monitor and switch to full-screen video view on another monitor.

Automatically restarting a meeting on a backup site

There is no automatic shared state recovery when a site becomes unavailable and automatically redirects to your backup site that was backed up with the Webex Global Site Backup (GSB) system. After the Meeting window reconnects to the meeting on a backup site, the shared state is lost and the presenter must start sharing content.

End-to-end encryption using PKI

End-to-end encryption of in-meeting data using a public and private key pair that is provided by the site administrator is no longer supported. End-to-end encryption in a live meeting continues to be available using an automatically generated session key only.

Denied access on iOS device after upgrade

You may be prevented from joining a meeting from your iOS device with the error message "The version of your Webex Meetings application is not compatible with the current Webex service. Upgrade the application now." This is because of a security option to enforce secure access after all mobile app upgrades.

Overlapping meetings prematurely ending

Overlapping meetings may end at the first meeting's end time sometimes.

For example, if a host schedules a daily repeat meeting with 24 hours duration with a starting time of 8:00 a.m. and the meeting supports joining before host 15 minutes before the meeting start, and if the host is not present, the meeting ends at 8:00 a.m. and host and participants must join the meeting again.

Limitations during screen sharing

You cannot interact with system applications on a remotely controlled computer, even if the presenter on that computer is sharing their screen.

Unable to join before host when meeting has already been started

When hosts schedule a meeting in Microsoft Outlook and check Attendees can join meeting X minutes before starting time, if the meeting has already been started before on the same day, participants can connect to the meeting audio using their computer only after the hosts starts the meeting. This is a security feature.

High frame rate content sharing

In Webex Meetings, there may be intermittent issues with some participants being able to see shared content when Optimized for motion and video is selected. A fix is planned for a future update. Until then, you may need to uncheck this option if the issue persists.

Unable to pair with Proximity

Webex Meetings desktop app can't pair with a public IP address device using Proximity for security reasons.

Remote Desktop Protocol

The Remote Desktop Protocol is not supported for Webex Meetings.

Certain meetings don't appear in your calendar without Hybrid Calendar

If you don't have Hybrid Calendar, the following meetings don’t appear in your calendar on your Webex site or the Webex Meetings app:

  • Personal Room meetings
  • Meetings that you didn't receive a direct invite to (forwarded invites or invites sent to a distribution list)
  • Meetings hosted on a different Webex site
