Error Message when attempting to open perfectly valid EXCEL workbooks
Can anyone help me with a simple issue? I have numerous EXCEL spreadsheets with .xlsx. I recently upgraded to OFFICE 21 and now whenever I try to open any of these from either the PINNED files or recently used file list, I almost always get the message "Excel annot open the file "filename" because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file" - I then have to BROWSE to the actual file and open it with no problems at all - what/why is this

- Patrick2788Silver ContributorYou may need to give the sync some time to update and then try the workbook again.
