Slow Join Times After a Major Upgrade

After a major WebEx 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.

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, even if the host has already joined the meeting. If this occurs, we recommend the alternate host assigns the host role back to the meeting host.

Windows 8.1, and 10

  • For file sharing, you must have Adobe Acrobat Reader to share PDFs.

  • When sharing Microsoft PowerPoint files in Print Driver mode, some content may not appear. We recommend that you use our standard Universal Communications Format (UCF) mode or use application sharing screen sharing instead.

  • When connecting to a remote computer with Windows 10, the local screen will not be able to be blacked out.

  • Meeting Center attendees are able to save Universal Communications Format Files (UCF) to their computers, even when the host has canceled the save privilege for them.

  • Windows apps do not appear in the Access Anywhere or Remote Access Add Application dialog box.

  • When a Mac participant of a Meeting Center meeting is sharing and annotating the whiteboard, the annotation color is incorrect when the square or oval shape is selected.

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.

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.

Microsoft Office PowerPoint

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

Shared documents display quality

WebEx 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 particularly pronounced when these documents contain images of text.

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, MOV, FLV, F4V, QT, and MP4.
  • MP4 and MOV video files cannot be shared in a WebEx Meeting if they cannot be played by the installed QuickTime player
  • 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

High-definition video

High-definition video is available for the main session only. There is no support for breakout sessions at this time.

High-quality video

High-quality video is available for the main session only. There is no support for breakout sessions at this time.

Operating system limitations

If you use Solaris or Linux you cannot:

  • Display UCF PowerPoint animations and transitions

  • Share UCF files

  • Cache course material before the session starts

  • See the attendee-ready indicator

  • Use WebEx integrated video

  • Record sessions with the WebEx Recorder or edit them with the WebEx Recording Editor

  • Play a training session recording file (WRF format) on Solaris or Linux

  • Use PCNow

  • Install the Integration to Microsoft Outlook

  • Conduct Hands-on Labs

The Linux platform does not support the new interface, Training Control panel, streaming video sharing, computer audio enhancements, new participant panel, and high-quality video behavior, including full-screen video behavior.

If you use the Mac platform you cannot:

  • Install integration to Microsoft Outlook

  • View PowerPoint Notes in a panel

  • Playback non-Quicktime movie format files during a session (only .MOV and .QT are supported)

  • Use Quick Start

  • Invite or Remind attendees from Session Option tray during full screen document sharing, application and desktop sharing

  • Set Hands-On Lab options

  • Record sessions to a local computer with the local WebEx Recorder or edit them with the WebEx Recording Editor (.WRF format only).

Other Mac limitations

  • Mac users can join only one session at a time.

  • If a host on a Mac assigns the Presenter role to an attendee on a Mac, and at the same time has polling list, invite options, or Q&A tab options open, these options do not automatically close for the new presenter if she does full-screen or Application/Desktop sharing

  • A host cannot start a session on a Mac simultaneously while viewing a WebEx Network Based Recording.

  • Chat and Q&A text box does not have a scroll bar when entering large amounts of text in the message

  • If an attendee switched to a presenter role while taking a test, they still can take the test.

  • Attendees can see the Presenter's Sharing menu during desktop share, if the latter is on an Intel Mac.

  • When doing desktop share, if Presenter tries to simultaneously assign attendees to breakout sessions from the Session Options tray, the panel overlaps the Assignment dialog and this dialog disappears if the presenter clicks anywhere on the desktop.

  • Scroll bar space for polls always appears, even if there is no scroll bar

Session options always appears on top of other windows if opened during desktop share and using other functions from the session options tray.

On-Demand Module availability

The On-Demand module (Training Center-Presentation Studio Integration) is not available in languages other than in English.

On-Demand Module authoring does not support non-Windows platforms. Player support is available for Windows and Mac. The following are known issues and limitations for Mac support of the On-Demand Module:

  • Mac support is based on Flip4Mac WMV version and higher. Feature support for the Mac is dependent on the corresponding support provided by Flip4Mac.

  • Certain codecs are not supported on Mac leading to audio playback issues. Note: Refer to for details on supported codecs in Flip4Mac.

  • If a file is inserted into a presentation, it will open up in a separate pop-up window during playback.

  • You have to turn on the Create streaming movies option to support streaming when an older version of Flip4Mac is installed (version to version If the Create streaming movies option is turned off, the viewer cannot play the presentation in streaming mode. By default, the option is turned off on the Mac and has to be turned on manually in the Flip4Mac System Preferences page.

  • If Real Player is used but is not installed on your computer, the Viewer setting page will remove the Real Player option. As a result, you will not have an option to view the presentation using Real Player.

Global Site backup availability

Global Site Backup (GSB) for the On-demand module (Training Center-Presentation Studio Integration) is only available for attendees who view recordings.

Sessions deleted automatically after ending

If a session is automatically deleted after it ends, as specified by the host, and then the attendees of that session are also invited to an On-Demand lab, those attendees do not receive any cancellations from the On-Demand session and there is no way for the host to manually cancel their invitations. However, when they try to join the lab, they will not be allowed to do so.

Attention tracking

If an attendee is on Solaris or Unix and they take a test within the session, they are assumed to be always paying attention in the session for as long as they are in the session during and after completing the test.

Registering for recurring sessions

In the case of single recurring sessions, if a registered attendee from a later session is manually invited by the presenter into the current ongoing session, they will lose their registration from the session they originally registered for and show up as an attendee of the current session in the usage reports.

Meta data name

The meta data name when entering data for SCORM 2004 cannot include certain special characters, even if the original session included these characters in the title.

Registering through email link

If an attendee is invited to register for a session and clicks on the email link to do so, their name is not pre-filled in the registration form.

Host account files

If your host user account is deleted, your files are still included in the site storage space allocation.

Network-based recording

  • The network-based Recorder does not record:

    • Private chat sessions with hosts

    • Polling results (unless the results are shared with attendees)

    • Test and breakout sessions

  • WebEx Advanced Recording Format (.ARF) files are supported in the UCF Viewer.

Disabling Quick Start

If your site administrator disables the Quick Start page in the session type and you save a scheduling template for this session type, Quick Start still appears in the template's options. However, the Quick Start page does not appear in the session.

Closing dialog windows in the Firefox browser

When using Firefox, some dialog windows may not close when clicking the Close or OK button due to a technical limitation with Firefox.
