Hi sssbbb,
Sorry for the inconvenience it may have caused.
I did a test from my side, but I cannot reproduce the same problem. My workbooks stored in OneDrive for Business and SharePoint Online will be listed in the Recent files, and I could also search for them.
To troubleshoot the issue you encountered, there’re some suggestions you may try:
- In Excel, click File > Account, remove the OneDrive for Business service you connected with, and re-connect it.
- Restore the Office account status.
- Sign out and close all Office apps.
- Access to the Credential Manager and select “Windows Credentials”.
- Remove all credentials beginning with “MicrosoftOffice16”.
- Restart and log into Excel.
If the issue persists, we would like to collect some information to further check it:
- Which version of Office do you have? After starting Excel, click on File > Account, please take a screenshot of the Product Information part and share it with us.
- Regarding the problem you mentioned, it would be great if you can provide some more details like screenshots of the interface.
Best regards,
Madoc
