Cannot Connect To Outlook365 On My Desktop

[tomohawk]

I use POP3 with Outlook.



I have Microsoft365 on my PC and Android phone.

I have been on vacation and have been accessing mail on my phone Outlook app without problem.

When I came back and opened Outlook app on my PC, I get a prompt to verify my email address and password (2 addresses) and then I get a fail message (attached).

I can still access on my phone and on Outlook Online.

I'm connecting to outlook.office365.com

Nothing has changed regarding address or password since before I went on vacation.

I have rebuilt my Outlook Profile, so that is not the issue.

For what it's worth, this sounds like what happened to me ( see separate thread ). It may be the case ( I do say 'maybe' ) that the timing of the problem, i.e. the fact of it happening when you returned from your holiday, might just be sheer coincidence. Given the fact that this will have paralysed what I would have thought would be a multitude of people, I'm surprised at how little mention of it there seems to be ( although, as in my own thread, I fully accept that it may just be me missing something ). You may want to keep an eye on my thread to see if any solutions do materialise, and likewise I'll keep an eye on yours.
