Solution 1Recommended

Verify Shared Mailbox Permissions and Account Synchronization

Ensure you have the correct permissions for the shared mailbox and that Outlook and Teams are using the exact same user account.

This error most commonly occurs due to a mismatch between the account logged into Microsoft Teams and the account used in Outlook, or insufficient permissions for the shared mailbox.

Verify Mailbox Permissions

Contact your IT administrator to confirm that your Microsoft 365 account has both 'Full Access' and 'Send As' permissions for the shared mailbox in question.

Check Account Synchronization

Open both Microsoft Outlook and Microsoft Teams. Click on your profile picture in both apps to confirm they are signed in using the exact same email address.

Open Meeting Options from Outlook

Instead of opening the meeting in Teams, go to your Outlook calendar, double-click the meeting event, and click the 'Meeting Options' link from the ribbon or the event description.

Verify Shared Mailbox Permissions and Account Synchronization

Account Consistency: Keeping your accounts perfectly synchronized across the Microsoft 365 ecosystem prevents most shared mailbox authentication errors.

Solution 2

Use a Private Browser Window

Bypass potential client cache issues or conflicting logged-in accounts by modifying the meeting options through a private web browser session.

Solution 3

Assign a Co-organizer or Check Licensing

Use the Teams co-organizer feature to grant modification permissions, or verify if the shared mailbox requires an active license.

Frequently Asked Questions

Why do I get the 'Only meeting organizers can make changes' error?

This error typically occurs when there is a mismatch between the account signed into Microsoft Teams and the one used in Outlook, or if you lack sufficient 'Full Access' and 'Send As' permissions for the shared mailbox that scheduled the meeting.

Can a co-organizer change meeting options in Teams?

Yes, if you are designated as a co-organizer for the meeting, you can modify most meeting options. However, you must first be assigned this role by the original meeting organizer.

Do shared mailboxes need a Microsoft 365 license for Teams meetings?

Generally, standard shared mailboxes do not require a separate license. However, specific advanced routing or complex meeting scenarios in Microsoft Teams might require the shared mailbox to be assigned an active Microsoft 365 license depending on your organization's configuration.
