Protecting a Microsoft 365 shared mailbox
Coro can protect Microsoft 365 shared mailboxes using the following two part process:
Verify your shared mailbox is appropriately licensed by Microsoft 365
In order for Coro to effectively protect shared mailboxes, it is crucial that your account is appropriately licensed by Microsoft 365. This ensures that Coro can apply security measures to the mailbox and provide the necessary protection.
To ensure your shared mailbox is appropriately licensed by Microsoft 365:
Sign in to your M365 admin portal:

Select Identity (previously Azure):

Select Users > All Users:

Use Search to Locate the shared mailbox:

Select the username displayed next to Identities:

Select the Properties tab:

Locate the Usage Location field:

If Usage Location is blank, select Settings:

Coro displays the Settings page:

Select a location from the Usage location dropdown:

Select Save:

Select Licenses:

Select the Microsoft 365 license to assign to the shared mailbox:

Select the Microsoft 365 license options to assign to the shared mailbox:

Select Save:

Refresh the page to confirm that the license is successfully attached to your shared mailbox.
Synchronize the shared mailbox with the Coro environment
After verifying your shared mailbox is appropriately licensed by Microsoft 365, synchronize the shared mailbox from the Coro Environment.
To synchronize the shared mailbox:
From the sidebar, select Control Panel.
Select Users:

If you have already added protection to all users or if the shared mailbox is a member of a protected group, select Sync from the Protected users or Protected groups tab:

Coro syncs and protects the shared mailbox.
If the shared mailbox is not part of any protected groups, it must be added to protection individually.
For further information, see Adding users and user groups for protection.
