Trouble emailing an Excel spreadsheet using File > Share > Send Workbook.

Don Meiner 0 Reputation points

I am using a Microsoft 365 Subscription, on a Mac, Version 16.85 (24051214).

I always share a spreadsheet using File > Share > Send Workbook.

Recently I have started receiving this message:

Microsoft Excel cannot access the file '/Users/Username/Library/Containers/ Office Send Mail/FileName.xlsx'. There are several possible reasons:

• The file name or path does not exist.

• The file is being used by another program.

• The workbook you are trying to save has the same name as a currently open workbook.

I cannot for the life of me figure out what has changed or where to look for a solution to fix this error. Can someone help me?

    Thanks for posting your question in the Microsoft Q&A forum.

    It seems that the issue is related to a temporary file path or directory that Excel is trying to access or create during the "Send Workbook" process.

    Sometimes, closing and reopening Excel can resolve temporary file or directory issues.

    Ensure that you have the necessary permissions to create and write files in the temporary directory mentioned in the error message

    Try clearing the temporary files and caches for Microsoft Office applications.

    Hi @Don Meiner

    Please try to remove cache files like below:

    • Close Excel, open Finder.
    • Press Command + Shift + G, input “~/Library/Containers”, move *** ***to desktop.
    • Press Command + Shift + G, input “~/Library/Preferences”, move to desktop.
    • Open Excel, and check if it works correctly.
