How can I block outlook 2007 from Exchange 365
For compliance and security, I would like to block users from using Outlook 2007 on Exchange 365.
Is there a way to block it?
- Hi, first of all. You really need to leave 2007. It has reached it’s ”end of life” since several years, see this https://techcommunity.microsoft.com/t5/office-apps/outlook-2007-connectivity-to-office-365-ending-in-oct-2017/m-p/34908
As for blocking legacy authentication https://docs.microsoft.com/en-us/azure/active-directory/conditional-access/howto-conditional-access-policy-block-legacy
