Are there missing features or known issues with the Office 365 Outlook Add-In?
The GoToMeeting team is working on resolving these missing features and known issues of the Office 365 Outlook Add-In.
Why aren't my meeting updates syncing between my calendar and GoToMeeting account?
It is highly recommended that you only schedule, update and/or remove meetings in Outlook and click Update meeting to push changes to GoToMeeting. This is because while all changes made with the add-in can manually be updated to reflect in your GoToMeeting web account, changes made in the web account are not synced and duplicated in Outlook.
