Sounds like a bug with Outlook 2010. It may be that  some of the server settings in Outlook 2010 are getting lost or reset when it resumes from Sleep in Windows 11.

Does it work ok if you just close down Outlook and then reopen it? (That is without shutting down the laptop itself.)

Does it still happen if you Hibernate the laptop rather then put in into Sleep?

Microsoft  stopped supporting the Office 2010 2 years ago ( )  so any bugs that have cropped up since then will not be fixed.

Hi Coenoby - thanks for the reply

Outlook works ok if it is closed and re-opened but I have not used the hibernate option, will do today and report back

Hi Coenoby - looks like the hibernate option works !!


So I will continue using that option - thanks
