I am trying to import an ost file. However, I'm getting this error. How can I fix this. I do not have the same username any longer. I found something on here but it really didn't help me. I am not too familiar with how exchange servers work. It is in Outlook 2003 format. My main goal is actually just to backup all of the events that are listed on the Calendar.
The file <filename>.ost cannot be accessed because it has been configured for use with a different mailbox
