Stop Users Adding Exchange Email Addresses

Copper Contributor

Hi All,

 

Is there a way to stop users in Outlook 365 from adding Exchange email addresses that are not their sign in address??

or is there a way to just block the accounts wizard?

 

I know we can block a range of other email address types, but I don't want people adding any other mailboxes to their work PC's.

 

Hopefully someone has an answer.

 

Thanks!

There was another topic about that: thttps://techcommunity.microsoft.com/t5/microsoft-intune/how-to-block-user-self-adding-personal-email-accont-to-outlook/m-p/3281464 . Does that help?
Any update?

@Harm_Veenstra ,

 

Thanks for that suggestion.

 

It partially works, it doesn't work on the new Outlook though, and we've got a few users using the new UI.

 

Do you know if there is a new key to stop it for Outlook(New)?

 

Let me know.

 

Thanks ! 

@Well_Connected_IT You could try this. It will lock the Outlook profile completely
