Cause:

This issue may occur for the following reasons:

• The meeting host may have accidentally forwarded the (host's) meeting confirmation email instead of the attendee invitation. The attendee invitation email contains different information and a separate link to the meeting.
• The link in the email may have been cut short or truncated due to word wrapping making the link invalid.

2. Locate the appropriate meeting on the Browse Meetings page.
