Send Outlook Email COMException


Send Outlook email activity is throwing following error. Can you advise how to fix this?
Outlook Error

Thanks in advance.

Could you resolve the issues. I am also facing the same problem.

For me the issue was multiple outlook accounts were configured on the same user account. Office 365 re-install helped resolve this issue.
This error showed up on a different system as well. To resolve there, I noticed, if this error shows up only when I have Outlook open. If I close the Outlook app, then this error didn’t show up.
Hope this helps.
