Hello i have a weird problem
I add a 2013 exchange server to my 2010 exchange server
When i migrate a user mailbox from 2010 to 2013 exchange server when a user log in for the first time on a new computer and launch outlook he get the error
Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance.
My mail profil is created and every options seem ok (username + server name)
If i delete the file C:\Program Files (x86)\Microsoft Office\custom15.prf then outlook is londing fine
I joined my file to the question. Is there something wrong in it ?
