Outlook email

[Joe]

I sometime leave message as unread after I have read them as a reminder that
I have a task to perform. However, today I mistakenly marked all of my
messages as read. Is there a way to undo this error? Thanks, Joe

No, Outlook doesn't track messages that were unread moments ago.

Select all messages, right click and select Mark as Unread.
