Hello, I'm Jen, I'm happy to help you today. Have you checked to make sure that your computer's date and time settings are correct? Sometimes, the computer times may interfere with the Teams calendar. Have you checked to confirm that your Outlook calendar is set as the default calendar in your Outlook settings? Could you please check to ensure that you have granted Teams permission to access your calendar? To do this, go to your Teams settings, click on "Permissions," and make sure that the "Calendar" option is turned on. If the issue persists, try signing out of Teams and signing back in again Let us know how it goes, we're here to help you further if needed. Jen A.

Hello Jen,

We are migrating from Google Workspace to Microsoft 365. Currently we are migrating the Microsoft Teams app. I have installed the Google Workspace add-on for Microsoft Teams on Google Admin center from Marketplace - the add on gets synced on the user calanders. We have identified 2 issues entire org wide:

The Microsoft Teams add-on on Google Calendar doesn't pick any meeting which doesn't have Teams meeting in it. It only recognises a calendar invite which has a meeting info on it.
The Desktop version of Microsoft Teams doesn't not reflect any events from Google Calendar to Microsoft Teams calendar. Even the ones which were synced on the Microsoft Teams Google Calendar Add-on.

We are on both Windows & Mac platforms. Any help would be greatly appreciated.

Best Regards,

Ravi

Hello Jen,

Our company has just synced AD user to MS 365, then all the MS Teams can not access calendar.

I have check Outlook Calendar default calendar, and check computer date time.

However, I don't know what Teams settings you are talking about. Is that the Setting menu in MS Teams app? In menu Setting, there is only App Permission, there is no Permission in which I can find Calendar option.

The error from MS Teams app is: Error Code = TokenGenerationFailed Error Message = Could not generate tokens to connect to the user exchange endpoint returned by AutoDV2.

Please kindly help, this affect 120 users in our company. Thank you
