Solved Unactivated Outlook app has taken over or updated the Outlook.live.com web UI and I cannot get out of it.

Try3 (Denis) recommended I create a new post here from:


Upon opening Outlook classic app on Win 11 Pro laptop:

PRODUCT NOTICE Outlook hasn't been activated. To keep using Outlook without interruption, activate before Tuesday, October 14, 2025 -- Activate button --

Summary: I only started accessing the Outlook apps to backup my mail to pst files since the webmail doesn't seem to permit this. But using the apps does, so I got what I needed, but the webmail UI changed to match that of the apps and It appears I will be forced to subscribe by tuesday in order to keep using my outlook mail! I just want my old basic Outlook.live.com UI back until I finish migrating elsewhere.


Outlook.live.com (what I'll refer to as webmail for now on) NOT MSOffice Outlook or the Outlook apps doesn't have an option to download pst files in settings, so I accidentally installed the new Outlook app and then reverted to classic app which was already on my system and I even installed officeSetup.exe at one point which I removed.


In the process of setting these apps up & logging in on my win 11 pro laptop -- including annoying Microsoft verify dialogs or whatever where they required my account PIN or to create one etc -- my outlook webmail UI has changed in appearance to match the apps UI no matter what pc or web browser i use. (except for access to import/export settings for pst files, of course!) And in order to use the app for messing with pst files, I was forced to select a 5 day trial (by the 14th) ie I couldn't just click off the dialog pop-up window and use the app for free to continue working with pst files.

So "in order to avoid service interupptions" it appears they're forcing me to pay now even to use the webmail unless this is just a spurious dialog I can ignore that only relates to using the app or if I can somehow undo all this mess and get back to the regular web version!

I need to continue to forward mails to my new email provider AND have access to my mail! and it would be nice if I could do this free as I have been using outlook.live.com for free all along.

And now I can't recall if the activation message ever appeared at Outlook.live.com on any PC/browser combination I have or just in the app!



USING:
Windows 11 Pro Version 23H2 OS build 22631.5909 Experience Windows Feature Experience Pack 1000.22700.1106.0

I use Both.

I just wanted to follow up:

I'm still receiving mail after the 5 day free trial I was forced to select in order to continue using outlook classic app! It claims until you login you can only use the app with limitations as read-only or print-only etc I forget ie with limited functionality which I haven't tested because my main goal was to get my account pst files.

The classic app allows you to download your account pst files for free whereas the New outlook app seems to force you to subscribe to office365, although I didn't mess around with it enough to see if it actually forces this.

My outlook.live.com (webmail) UI is still altered in appearance to that of the app, but no pst file access there nor was there previously in the webmail.

Hope this helps somebody who's trying to migrate their email to a new service while trying to understand how to navigate Outlook mail apps.

I'm going to mark this as solved.
