Issue:
Whenever I try to open Outlook, I get this error:
“Outlook is using an old copy of your Outlook data file (.ost). Exit Outlook, delete the file, and restart Outlook. A new file will be automatically created the next time you initiate a send/receive.”
Cause for the error:
You will encounter the above message when Outlook is unable to open latest OST file due to an issue with Outlook Email client or Windows OS.
Resolution:
One of the easiest ways to resolve this error is to delete old Offline Storage Tables or OST file. OST or Offline storage Tables are located in C-Drive of your computer: C:\Users\<your login
name>\AppData\Local\Microsoft\Outlook.
Do not forget to backup your OST file in the form of PST file, before its deletion for the simple reason that in case there is data loss, you can retrieve data in MS Outlook through the backed up PST file. OST to PST file conversion is easily possible with Remo OST to PST Converter software.
To delete the OST file, follow these steps
- Go to the Computer or File Explorer window,
- Navigate to C:\Users\<your login name>\AppData\Local\Microsoft\Outlook
- Delete files with .ost extension
- Take care to not delete any file with .pst extension
Restart Outlook; the OST file will be recreated.
If you still stuck with the same problem even after deleting the old OST file, below mentioned steps will help resolve the error Outlook is using an old copy of your Outlook Data File (.ost). Exit Outlook Delete the file:
