What causes the Mailbox not found, please contact your system admin message when in Canvas you sync Microsoft Teams meetings, then in Teams activate the class and then go back to Canvas MS Teams meetings and try to schedule a channel meeting?

Bunnell, Jennifer L 0

We are starting to use Microsoft Teams meetings in our Canvas courses. But get the error message "Mailbox not found, please contact your system admin" when trying to schedule a channel meeting. This happens when we use the following steps.

In a Canvas course, we turn on the Microsoft Sync state and click on the Sync now button.
Then in Teams, activate the Class
Then, back in the Canvas course, you access the Microsoft Teams meetings link (sign in if necessary) and try to schedule a channel meeting.

Note: If the user disregards that meeting, they can create a regular meeting where you instead use the option Add entire class.

Also, after a long period of time, you can eventually create a Channel meeting. Any help would be greatly appreciated as to what causes this.

Thanks

Hi @Bunnell, Jennifer LIt sounds like you're encountering an issue where the necessary mailbox permissions or synchronization between Canvas and Microsoft Teams are not aligning properly. Here are a few steps you can take to potentially resolve this issue:

Check Mailbox Setup: Ensure that all users have their mailboxes properly set up in Microsoft Office 365. The error message suggests that Teams is unable to find the associated mailbox for the user trying to schedule the meeting.

Verify Azure AD Sync: Make sure that the Azure Active Directory (AD) Sync between your institution's directory and Office 365 is working properly. Sometimes delays or issues in synchronization can cause such errors.

Ensure Permissions: Verify that the user trying to schedule the meeting has the appropriate permissions in both Canvas and Microsoft Teams. They should have the necessary roles and permissions to create and schedule meetings in the specified channel.

Hi @JimmyYang-MSFT As we continue testing, it seems like a sync lag issue specifically with Channel meetings, since we can make a regular meeting without delay. We will continue to test this but I hope this is something that can be improved with Microsoft in the future.
