Microsoft Excel includes a handy Send as Attachment option that enables users to attach Excel spreadsheet files to Outlook emails.
However, some users have posted on software support forums about a General mail failure Excel error.
That error message can pop up when users try to attach spreadsheets to Outlook emails from within Excel.
Consequently, they can’t attach Excel files to emails with the application’s Send as Attachment feature. Below are some potential resolutions for fixing the General mail failure issue.
What can I do if my Excel file is not attaching to an email?
1. Send it as a different format
If Outlook rejects attaching the Excel file, you can also disguise it cleverly in another format. The best way to do that is to compress the file by using WinZip.
To do that, find the Excel file on your computer, right-click on it and select the Add to archive option. The newly obtained Zip file will be most likely accepted as an Outlook attachment.
Also, this software includes a file conversion option so you can transform your Excel file into another type and see if it gets accepted by Outlook.
WinZip is the most popular file archiving tool but it’s not only that because it evolved a lot during the last years.
Now, this excellent tool features many other tools like data encryption, data backup, file management, and even file merging.
