I'm a windows 11 user. Few days ago, I saw another outlook app which shows in the start as Outlook(new). I uninstalled it because I have the outlook in my office package, but few days later, it was again installed. I scanned that folder but there is no malware detected. What is this? And why is it installing again after I uninstall it? Is it a malware? Or a legitimate software? Pls advise ASAP.

Hi Mark,

Thank you for posting on the forum today. I’m Bambi, a user like you and I’ll be happy to assist you.

I believe you are referring to the new Outlook. Please see link for reference https://support.microsoft.com/office/656bb8d9-5a60-49b2-a98b-ba7822bc7627

This is set to replace the mail app, it may explain why it downloads itself. You could try using it and see if you like it first before you decide against using it.

I hope this answers your question. Let me know if there’s anything else I can help you with.

Best Regards, Bambi

    Thanks Hal & Sean. Keith - similar for me. After I had to go and reinstall mail & calendars, the work around I'm using is to just uninstall New outlook (again) and keep mail open. Have to keep it open and new outlook seems to not overtake it, but if you close or restart, the big bad brother returns to take over your computer and the world.

    Tried this. Removed all the registry entries listed there, it didn't do anything. Restarted the computer, as soon as I started Mail, it changed it into Outlook.

    Is there some other way to stop it doing this? Can I make the folder it installs to read-only?

    For the time being, you can temporarily bring Mail back by going to Settings > General > About Outlook and clicking the Open Mail now button.
