Teamspace members can save the credentials (user name and password) for the third-party meeting vendor used for meetings. Once the credentials are saved (by selecting the Save my credentials and don't show this again checkbox, the application will not prompt for them again. Because of this, when a user saves their credentials, the TCM application no longer displays the prompts for the user name and password, so users cannot change them, either.
Once a set of valid credentials have been saved, they cannot be changed through the TCM application user interface. An administrator with access to the Collaboration Store in the content engine can reset a user's meeting vendor credentials as follows:
Root Folder\Teamspaces\<teamspace name>\_internal\_members folder
Root Folder\Collaboration Store \Meeting Connection Templates\ WebEx Online Meetings
Users whose credentials have been reset (as well as users whose stored credentials become invalid for other reasons) are prompted to enter new credentials the next time they use a meeting feature that connects to the meeting server. They can enter and optionally save new credentials at that time.
