Random errors when adding emails to SmartSheet


One of our employees sometimes experiences issues trying add emails to SmartSheets.

When the issue occurs, everything works fine in Outlook until the last step -saving the email content to SmartSheet. At that point, she receives a message saying something like "Something unexpected happened..."

Sometimes waiting one or two days helps and the issue is gone (same email, same SmartSheet).

She has a PC computer.

Any tips on what the issue could be?

Thank you!
