Navigate to Notifications

Click on 'Edit settings' from the dropdown menu, and then select the 'Notifications' tab.

All Company Announcements: Notifications originating from an 'All Company' distribution list or mandatory Microsoft 365 group cannot be individually unsubscribed from within these settings.

Solution 2

Frequently Asked Questions

Why can't I turn off 'All Company' notifications for my shared mailbox?

Microsoft mandates that certain organization-wide announcements sent to the 'All Company' Microsoft 365 group reach all members. Individual accounts, including shared mailboxes within that group, cannot opt out of these specific administrative broadcasts.

Do I need a Viva Engage license for the shared mailbox to change settings?

If the shared mailbox is receiving emails, it is part of an M365 group and has an associated profile. You generally need to be able to log in or use delegated access to the Viva Engage profile associated with that account to access the settings menu.

Can Exchange transport rules block Viva Engage emails to shared mailboxes?

Yes, an Exchange administrator can create a mail flow rule (transport rule) in the Exchange Admin Center to silently drop or redirect emails originating from Viva Engage addresses that are sent specifically to the shared mailbox.
