I am trying to move everyone over to a centralised roaming location for OST files.
I am moving the OST file to the network location, deleting the existing mail profile, recreating the mail profile and pointing the data file to the network location.
That works perfectly. I check back hours later and it is still working perfectly.
Then the next day, I check back with a user and the mail profile I created has been removed completely and replaced with a default "Outlook" profile. The OSTs are pointed back to c:\users\..... again. I have been through every group policy object and there is nothing that points OST or PST files to the local hard drive.
What am I doing wrong? How are they coming back? Why does Outlook 2013 do this?
