Cannot log into my Hotmail address in windows Outlook but can on Outlook.com

In earlier versions of Office/outlook there was a limitation of 3x Hotmail accounts

Can you add this Hotmail account the win10 mail app?

i have always had 4 hotmail accounts active in windows outlook for a number of ytears through 2010 and 2013 versions.

i also have outlook on my other machine with the same hotmail address and it is fine.

what is win10 mail app?

i have been able to add this account via win10 mail app - so no problem there! 

However when i try and add it via desktop outlook, i still see the same issues. 

I reinstalled Outlook and this time when i tried to add this account i saw the traditional email config page. However when i tried the automatic configuration, whilst it was searching for this account, the small window asking for the password popped up. I input the password and clicked submit but i saw another error message i.e.

when i closed this 'cant reach page' window, the email config window continued and added the account as an exchange active sync account i.e.

I then decided to see what would happen if i removed this account on my other machine and re-add it. Perhaps not surprisingly, i saw the same issue i..e. it cant find my account !!

I decided to create a completely new Hotmail account to get some idea if it was my machine of Outlook.com.

After  successfully creating the new Hotmail account online, i went back to desktop outlook and tried to add this new account but saw the following !

in my mind there must be an issue with MS servers(??????)

please someone help with this utterly frustrating issue

Further to my previous message, I noticed when i created a new Hotmail account, i saw that I had the option to also create an outlook.com account via Outlook.com. 

I decided to create an outlook.com account and see what happened. 

I successfully created an outlook account and verified when i sent an email to myself. 

I then successfully added it to my Desktop Outlook app - however i was asked for the password a MILLION times which was extremely frustrating before it finally added the account. I then had to restart Outlook and when i reopened I was AGAIN!! asked for the password ! Anyway, the outlook.com account was successfully added. 

From what I can determine, whilst Outlook.com offers the option to either create a new Hotmail.com OR Outlook.com account, whilst I can add ALL these accounts to the WIN10 Mail app, the desktop Outlook will NOT accept/recognise any further Hotmail accounts. There is a real issue here!!!

I have exactly the same issue today!!!
That is insane. My mail functions anywhere else but outlook win 10 app.

At first I thought there might be any time of malware. I am trying to fix it 4 hours now with a ton of ways but no fix.

These random issues with any valid cause and no solution are super disturbing. I would relly appreciate a solution on that MS..
it seems that the problem is with some @hotmail.com accounts.....

Today, without warning, i saw a small popup window appear from the bottom right hand side advising there is a problem with a Microsoft account and told me to click here. When i did so i saw

after clicking 'fix now' i saw the following

this account is ALREADY in the list of added hotmail accounts in Win10 mail app and Outlook.com in Settings but i was able to add it to Desktop Outlook cos of the error i kept seeing as above.

after adding password i saw 

after putting in alternate email, i saw the following

after inputting the code i saw

the account is automatically added to desktop Outlook 

it would appear that this is a Microsoft issue but i dont understand how/why the system suddenly realises that there is a 'problem with a Microsoft account' ?!

As i still CANNOT manually add the other Hotmail accounts, i guess i will have to wait until the 'system' discovers a 'problem' with the outstanding Microsoft accounts and put it right as above.

NOT a satisfactory situation !!

i CANNOT EFFING BELIEVE IT !!!  After i submitting the most recent post above, i decided to see if i could add the 3 outstanding accounts to my desktop Outlook and I COULD !! 

And this was without providing a password !!

So after wasting all that time last week trying to sort this out, in the end the 'system' sorted itself out !!  I am furious with Microsoft !
