Disable Automapping for Mailboxes from Admin Center
Proposal: Have the option through GUI to disable automapping for inboxes, and/or certain individuals that have permission to that inbox.
Explanation: When you assign permissions for someone to a particular inbox (including shared) it automatically adds the mailbox to their Outlook profile - this has caused us issues. While it can be disabled through PowerShell, it's very tedious to go through and remove each user and then add each user to every inbox with automapping disabled.

We can disable it using PowerShell, but it is very time-consuming as we have to remove the access rights for each user and re-grant them.
Therefore, we would like the ability to disable auto-mapping in the GUI.

please enable a feature to disable automapping over the entire organization and I agree with Gabriel that the process to remove and readd user's permissions is tedious. I am sure we can find a way to simplify this process.
It would be fantastic to have option on Admin panel to enable or disable Automapping for Outlook without using PowerShell commands.
This is proposed as part of another request for automapping management features
