Can't add an email account to my PC

I run Office 365 on my tenancy - I'm the global administrator. I recently added myself another email account. No issues there.

I added it OK to Outlook on my desktop PC. It's running the latest Office 365. No issues there.

Come to add the account to my laptop PC and it just keeps looping asking for the password. If I put the wrong password in, it tells me it's wrong. If I put the correct password in, it just either hangs up spinning saying 'adding account' or will ask me to re-enter my password.

I'm running the latest Windows 10 and the latest Office 365 (subscription from my Office 365 tenancy license) on both machines. All updates applied.

I've tried creating a new profile on my laptop and adding it there - no difference. Both PCs are in my house on the same network.

Anyone got any thoughts on this?

Cheers

Alan, I'm just taking a guess here, but I suspect that if you are using 2 factor authentication, it's possible that you may need to generate an "app password" for Outlook to use.

Goto https://account.microsoft.com/ > Security > Additional security options > Scroll down to the "App passwords" section.

When you navigate to that location there is a link to more information about app passwords as well if you want to understand why these are needed.

I'm not using 2FA at all. Never have done.

I just set it up on my phone and it worked fine.

And I don't have too many accounts.

Apologies for a wrong guess. Hopefully someone else has some thoughts on the matter.

As I said, It's an Office 365 account.

At 3am this morning, I added another account and that one was fine on my laptop. I just need to see if it works on my desktop now.

It's very weird. The autodiscover XML does get created, but it still keeps asking for the password.

No it didn't work.

I've since discovered that O365 hadn't actually created an Exchange account associated with the name. So god knows how it ever worked at all.

I'm leaving it all for a week or so. I think there's server issues somewhere.
