If your Outlook data file name has changed or appears rearranged, it may be due to the creation of a new .ost file or changes in your Outlook profile. By default, Outlook creates an Outlook.ost file for local caching, and if there is already an existing .ost file, Outlook may append a number to the file name (e.g., Outlook0.ost, Outlook1.ost).
To check the current data file being used:
If you need to ensure that your Outlook is using the correct data file, you can set your Exchange account as the default delivery location, which typically uses an .ost file. If you are experiencing issues, you may also consider creating a new Outlook profile or repairing the existing one.
