Question

How can I stop users from adding personal account to the new Outlook in windows using Intune.

For now we can only block Personal Microsoft accounts ( hotmail.com, outlook.com etc ) with intune. but Gmail still works. is there anyway to block this? We only want our corporate accounts to be added and nothing else

@Martin Buist, Thanks for posting in Q&A.

From your description, I know you want to stop users from adding personal account to the new Outlook in windows using Intune.

Based on my research, here are methods for Outlook 2016 and maybe possible for new Outlook you can try.

Method1:

We can create a configuration policy - settings catalog - with 1 or 2 settings:

prevent adding non-default Exchange accounts

And

Prevent personal Microsoft accounts from using MAPI

Method2:

We can create a setting catalog profile. Search for "Block signing into Office (User)", click on "Microsoft Office 2016\Miscellaneous" and add configuration:

 

 

Enable the configuration setting to enable and select ORG ID only

 

 

Moreover, we can consider achieving it via GPO.

Here is a link you can refer.
