When attempting to save existing files I regularly (at least once a day) I get the following error message.
"Errors were detected while saving (file name). Microsoft Excel may be able to save the file by removing or repairing some features. To make the repairs in a new file, click Continue. To cancel saving the file, click Cancel."
When you click continue it takes you to the save as screen, but all attempts to save it on an alternate network drive, locally, renamed in the same folder result in a "Document not saved." pop up. I then have to close the workbook losing everything
done since the last save and reopen to correct the problem.
The problem occurs in various workbooks (some running a power pivot, some not) and various scenarios (after multiple previous session saves, first session save attempt, multiple workbooks open, single workbook open) so I can't replicate the issue.
Running:
Windows 7 Service Pack 1
64 bit OS
Office 2013 Pro Plus
