Hello,

Thunderbird won't accept an e-mail of mine no matter what. I get the message "Configuration Could not be verified - Is the username or password wrong?"

Things I tried: 1- Disabled Two Factors 2- Disabled all securities on e-mail 3- Allowed POP/IMAP from outlook 4- Made the password super easy and 8 digits. 5- Restart PC, Restart Browsers, Logout, change passwords etc.

All my other emails work on thunderbird, why is it that this email is like that? it got the same settings as other emails and nothing is different.

My E-Mail is @outlook.com. Today I've added around 15 accounts to thunderbird doing the same process. All of them worked, except this one! Please help!

Actually, I found out that there's a problem with the email itself. That e-mail can't even receive any emails from anyone, as it shows "mailbox unavailable" even though I can log into it, see the intial email microsoft sends you when you just made an account, and even activate 2FA and such.

Also that email can't send emails to any recipents even from outlook website. I guess since the issue is the email itself, and i just created it minutes ago, I decided to delete it and I'll just create a different one instead.

Pretty weird don't know what caused it, but it's kinda registered bugged.

What is the time between checking mail?

Outlook has a 15 minute limit and I wonder if it is refusing further connections because your 15 other accounts are all logging in from the same IP address within that period
