Change The Mail Delivery Location
Another solution is to add a new data file and set Outlook to use it to store your emails. This will create a fresh data file for Outlook and will usually fix the “Outlook data file cannot be opened” error.
Open the Start Menu and launch Outlook.
Click the File tab at the top of your screen.
Select Info from the options in the left sidebar. Then click Account Settings on the right-hand side pane and select Account Settings again.
By default, you’ll be in the Email tab. Switch to the Data Files tab and click the Add button to add a new data file.
Outlook will ask where you’d like to save the file. Choose a location, enter a name for the file, and click OK to save the file.
Outlook will still use your old data file to save your messages. Change that by setting your new data file as the default data file. Select your newly created file in the list and click Set as Default at the top.
Hope this helps,
