Hi, I had to install Outlook 2007 anew after a system crash. After the instatllation the programm has all the foregoing data assumed. But when I will receive emails from my server I get now always the message:


The target principal name is incorrect
Do you want to continue using this server?


But this really depressive.
What is to do??

I moved your post to the Outlook form from the Word forum.

Outlook 2007 is about 15 years old and out of support. You are using Windows 11?

I'm sorry, I do not have an answer for you because I primarily answer questions about Word. Someone else here may be able to help you, though.

OUTLOOK 2007 worked since 15 years without problems. I think now, that it should be a problem of the server I use?? It is GMX, but I don't see there some help.
