Remove EOL Automapping

Automapping is an Exchange & Exchange Online feature which automatically opens mailboxes with Full Access permissions in a delegate’s Outlook client.

Remove the access permissions. This also removes automapping.

Logon to Azure EOL (with MFA)

Business@contoso.ie is the mailbox being shared.
anna.grimm@contoso.ie is the account that has the access rights.

In EOL PowerShell

Remove-MailboxPermission -Identity “Business@contoso.ie” -User “anna.grimm@contoso.ie” -AccessRights FullAccess                                                   

Confirm

Are you sure you want to perform this action?

Removing mailbox permission Identity:”Business@contoso.ie” for user “anna.grimm@contoso.ie” with access rights “‘FullAccess'”.

[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [?] Help (default is “Y”): select A

You might get this error
WARNING

Can’t remove the access control entry on the object “User” for the user account because the ACE doesn’t exist on the object.

So use

Remove-MailboxPermission -Identity “Business@contoso.ie” -User “anna.grimm@contoso.ie” -AccessRights FullAccess –Confirm:$false –BypassMasterAccountSid

Re-add the permissions but without Automapping

Add-MailboxPermission -Identity “Business@comtoso.ie” -User “anna.grimm@contoso.ie” -AccessRights FullAccess -AutoMapping:$false
