Outlook 2013 Standard keep asking password when shared mailbox auto mapping
license@microsoft.com <- licensing mailbox shared@microsoft.com <- shared mailbox If granted permission to the licensing mailbox access the shared mailbox, on the Outlook 2013 Standard will show...
Is this for O365/Exchange online? Where are the mailboxes located? Do you have Modern authentication enabled?
Yes, we are using O355 include exchange online. (Licenses - Office 365 Business Essentials)
The MFA is disabled.
I found out this issue is caused by a shared mailbox info@xxxx.com only.
If granted the permission to access other shared mailbox, no any issue will happen.
But no any difference between these shared mailboxes setting......
