In Exchange 2013, Outlook finds a new connection point made up of the user’s mailbox GUID + @ + the domain portion of the user’s primary SMTP address. This change makes
it much less likely that users will see the dreaded message “Your administrator has made a change to your mailbox.”

Although the error message in the topic has been already improved a lot in Exchange 2013, the users may still encounter them in some specific scenarios. We have collected them and let’s discuss them in this thread.
Symptom
=======================================
Consider the following scenario:
- Exchange 2013 was installed for a migration from Exchange 2007/2010.
- The legacy Exchange server is removed after successful migration.
- Exchange 2013 may be updated to Exchange 2013 SP1.
Some users were being randomly prompted with a popup in their outlook client with the following message when connecting with Exchange 2013 server:
“The Microsoft Exchange Administrator has made a change that requires you quit and restart Outlook”
Cause
=======================================
The issue may be caused due to Public Folders.
The msExchHomePublicMDB attribute on Exchange 2013 databases was set to deleted legacy public folder object.
Solution
=======================================
Removed the Public Folder from all the Exchange
2013 Databases. To do it, we can use ADSIedit.msc and remove the arrtibute - msExchHomePublicMDB from all the Databases:
1. Open ADSIEdit.
2. Connect to the Configuration container.3.
Expand Configuration, expand CN=Configuration,DC=Domain,DC=com.4. Expand CN=Services -> CN=Microsoft Exchange -> CN=Domain -> CN=Administrative Groups -> CN=Exchange
Administrative Group -> CN=Databases.5. In the right hand pane you will see a list of databases.6.
Right-click the listed database object -> Properties.7. Check whether the msExchHomePublicMDB value is set to an unavailable value. If you see reference to the old database,
please clear the value.8. Click OK.9. Check the rest of the databases to make sure
that they are not populated in the same way.
