Dear all,
I have the issue with number of the users who can't connect to the mailbox after migration from 2010 to 2013 Exchange server.
If I go to Exchange Proxy settings in Outlook it still points to old URL records, when I change URL to the Exchange 2013 it works ok, but after closing the Outlook the problem appears again.
Mailboxes are copied to Exchange 2013 without any problems
Please, help
Thank you in advance
