I have a user who has Outlook 2010 in cache mode. We have several users setup this way with our Exchange 2010 server. I have confirmed that he has a local .ost file that is current in the C:\Users\username\AppData\Local\Microsoft\Outlook folder.
However, when I look under the account settings > Data File tab, it shows 'online' as the location for this users .ost. This seems odd as mine shows the path as shown above.
Why would it say online and can that be causing problems? Is there a way to change it to the users folder, or does the mailbox need to be rebuilt?
