Issue
Is it possible to restrict non-admins access to the Crossware portal? At the moment non-admins have Read-Only access.
Can we remove access to the Crossware portal completely for non-admins?
Solution
It is possible to restrict access to the Application via the Admin Center.
Below are the steps:
1. From the "Admin centers" go to "Azure Active Directory"
2. Go to "Enterprise applications"
3. Open the "Crossware Mail Signature for M365" Application
4. Enable the "User assignment required?" field.
Changes may take 40 minutes to take effect, please try logging on to the Portal as a Standard User, then as a Global Admin.
