Prevent other accounts in OneDrive and Outlook

[Wazza22]

What about a policy to:

• prevent adding other accounts including other M365 to OneDrive - lock down to only the primary tenant (prevent data leakage)
• prevent adding other accounts to Outlook from outside the primary tenant (prevent data leakage)

Hi there!

So the existing OneDrive policies already includes the setting "Allow syncing OneDrive accounts for only specific organizations" and during import it should automatically fill the Tenant ID of your tenant.

As far as restricting adding of other email accounts, I did attempt doing this some time ago but the settings never worked as expected. If you find settings that do work, by all means let me know!

I have a policy that seems to work for Outlook - its in JSON format - how best to share with you as would be amazing if you could include in your project?
