Pop up “your Microsoft account brings everything together keeps appearing on my outlook page and on Microsoft Word. I can’t close it and it prevents me from using those functions.

Resolution too high was my problem also, thank you so much.

I just resolved this problem utilizing the Microsoft Help service. In my case, the problem was that my Resolution setting was too high, so the bottom of the Notification or Pop-Up did not appear and I was unable to scroll or move the the Pop-Up to bring the critical "Learn More" (or words to that effect) Button into view on my 14" laptop. By reducing my type size way down, the full Pop-Up appeared on the screen, revealing the critical button which allowed me to jump thru the requisite Microsoft hoops and resolve the Pop-Up.

To address the Resolution issue, in Windows 11 just click on your START button, then select Settings, Display, Scale (in the section entitled "Scale & Layout"). My size setting had been 175%. I reduced to 100%, which did the trick. But you may want to go lower until the full Pop-Up is in view on your screen.

None of this should have been necessary, of course. Oh well...

I can't get rid of your Microsoft account brings everything together on Excel or Word. Can't use programs

Hope someone has an answer.

It's not really a notification. Looks more like an ad that keeps coming back. See Attachment. Has anyone have the answer? You can close it if you go to far left of the top bar, right click.
