My outlook is stuck on the new version. How to go back to classic version?

Hi All,

I'm experienced the same situation and the change registery is not helping because by default it's already '0'.

I would suggest if you already open the classic mode try to pin to task bar, so there will be another MS Outlook logo in the task bar and every time you klik and open it, it will run on classic mode.

Hope this help.

Thank and regards,
Ronny

Thank you Hal. I upgraded to Windows 11 from Windows 10, but my BIOS had to be updated as well. As a result I had to reinstall some of my software and rebuild some of my files, and reinstall MS Office. For some reason the only option I had was the new Outlook. Even when I toggled the switch at the top right all I could do is respond as to why I didn't like the new Outlook and then Outlook would just disappear. My only option was to reopen to the new Outlook. For whatever reason, following the link you gave me completely reinstalled Office and now I am back to where I was, with the option to use either version of Outlook. Thank you!!

Not sure if this is true for other users but one of my issues with the new Outlook is that mail seems to take quite a while to send, and if I'm not careful I've closed the program and gone on to other tasks without realizing it was never sent. That is not an issue with Classic.

Thank you again.

I'm now stuck using the new version of Outlook. I hate it!! Why does Microsoft FORCE/TRICK YOU to use the new program. Maybe because they know you won't do it willingly because it's to awful. Every day I struggle to just DO a regular daily task. I've got to find another program to use!!

i am lost and my computor is useless withthe new outlook, i need live help
