Solved: The file <filename>.ost cannot be accessed

[kevinpier440]

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 2007 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.

You need to be an Administrator and to "take ownership" of the file.

So you can access the OST on another machine?
If so then create a pst and then copy the calander from the ost to the pst.

And don't forget for the method above you need to run scanpst from outlook.
