This account is not supported in Outlook for Windows due to the license provided by your work or school

Switching from Microsoft to Google? I honestly don't think they will care...

"In addition to cloud computing, Google and Microsoft have also collaborated on a number of other projects, including:

• Bing: Google and Microsoft have a joint venture called Bing, which is a search engine that competes with Google Search.
• Office 365: Google and Microsoft have a partnership that allows Google Apps users to access Office 365 documents.
• Android: Google and Microsoft have worked together to develop Android, an operating system for mobile devices." ~ QUORA

Another tid-bit...

"Your Gmail address is actually just an alias for your Microsoft account and not a real Google account"

Stop spreading lies. Microsoft & Google are rivals, especially when it comes to search engine. Few months ago Microsoft CEO event testified against Google in court that there's no Internet but only Google, complaining that people aren't interested in his crappy Bing.

Lastly you should never use Quora as a source. This idiotic site should be burned to the ground once and for all!

Well i did not realise that about Quora. Thanks for the insight and my apologise for posting that misinformation. However, the 2nd comment relating to Gmail was from the Microsoft site itself so i'm not sure how to take that now. The information i found was that yes, they used to be rivals but have been working together in several instances.

Since your comment i did a bit more searching using 2024 as a key and according to the Wall Street Journal, it does seem there's a black cloud over their 'cease-fire' once again. Please don't tell me that a source like WSJ is also utter rubbish

Yes! if i switch back to the old version, both the accounts show up. It's just the new version that i can't add the new account. But the weird thing is i've been on the new version for almost 1 year with both my accounts linked. All of a sudden one gets dropped and i can't add it back on. Something doesn't make sense! Why was it perfectly fine, then all of a sudden not?

That's the frustrating part!

Here's what happened:

In Windows 10 we had app called "Mail" which actually worked fine with any licenses and accounts. They continued to give us this mail app in Windows 11 too. However later, Microsoft decided that it was time to kill this app and replace it with a new Outlook (something they're always good at). So, people updated this mail app to this new Outlook and again you could add any licenses there just like in mail app with no problems. I did too by the way. Then, later, "geniuses" at Microsoft thought: "Why not make a more money out of this, lets put ads in this new Outlook and let's restrict basic plan licenses to use it, so they will be forced to upgrade to "standard" version and we make more money". So, on a next update we got ads in Inbox disguised as an emails and if you log out and try to login with your basic plan subscribtion you get this error". So, either you're forced to pay more money to use this new Outlook, either walk away and switch to other company services. Personally, as a protest and a matter of principle, I refuse to pay more and use their new crappy Outlook and I'm sticking to Gmail instead. I also completely uninstalled their OneDrive and decided to upgrade my free Google drive to Basic version and pay for it to support Google instead of Microsoft as a boycott this vile, atrocious company. I advise everyone to do the same. The less customers Microsoft will have, more likely they will be forced to back down.

I have Tenant accounts under our 365 License, and they cannot be added. They worked until today?
