To all,
We will be beginning to migrate mailboxes to the new Exchange 2013 servers in the next week or two and I wanted to make you aware of some issues that we are seeing during our migrating in North and South America.
While we are migrating mailboxes to the new Exchange servers, some users keep getting the message "The Microsoft Exchange Administrator has made a change that requires you quit and restart Outlook".
Please see the article below for the potential fixes.
Any of the reasons here can cause it, as we are migrating mailboxes every evening.
