I need to recover outlook ost file and  make it a pst
Watch Question


I have received an: Internal error (code=0000000E)
Message and nothing happened to my OST file, except, that I had a backup of it with PST extenstion, which is still an unacceptable format to Outlook 2007. The OST file comes from an Outlook 2003 program

1. Open Outlook and choose to work offline, this will create and .ost for you existing account.
2. Close Outlook
3. Rename the outlook.ost created in C:\Documents and Settings\"your Profile"\Local Settings\Application Data\Microsoft\Outlook to outlook.ost.old
4. Copy the ost. you are trying to convert into the folder containing outlook.ost.old
5. Open Outlook, this will open the .ost
6. Export to .pst


what do you mean export the .pst? i followed your directions up to #5. i opened outlook and it worked. i then unchecked "work offline" and it kept all the data. do i need to do anything else?? or is it now in the pst?
