My work btconnect (Allamoco) account is not working.

David_Dorset1 — Wed, 01 Apr 2026 22:29:11 GMT

I last received an email on my work Allamoco btconnect account, I think, Saturday it was from another Linked in account. Coming to logon into my emails today I found a prompt asking me to sign into the Allamoco account.

I went onto Microsoft 365 and when trying to log on to the account it said the email account wasn't recognised. So I asked to reset the account using dual authentication. I received the Microsoft emails with the codes and duly entered these to restart the account and set a new password, which seems to work.

However, when I try to sign on my Allamoco btconnect account with the new password, it again says this account is not recognised. How do I fix this? Do I need to contact anyone?

Additional FY!: This is the specific 365 error message "This username may be incorrect. Make sure you typed it correctly. Otherwise, contact your admin."

Hi 👋 thanks for explaining this so clearly — that error message is a useful clue.

What’s happening here is that your btconnect email address and Microsoft 365 sign‑in aren’t the same thing, even though they appear linked.

Why this is happening

Your @btconnect.com mailbox is part of a BT‑managed Microsoft 365 tenant
When Microsoft says “This username may be incorrect… contact your admin”, it usually means:
- The mailbox has been removed, disabled, or unlicensed, or
- The account no longer exists in the tenant you’re trying to sign into
Resetting the password works at a Microsoft level, but won’t restore access if the mailbox itself is no longer active or recognised by BT’s system

What you should do next

This isn’t something you can fix yourself, unfortunately — it needs to be checked by BT:

📞 Call BT Business Support: 0800 800 154
(They can check the status of your btconnect mailbox and Microsoft 365 licence)
🌐 Online support & contact options:
👉 https://business.bt.com/help/contact-us/

Ask them to:

Confirm whether the btconnect mailbox still exists
Check the Microsoft 365 licence and account status
Restore or re‑provision the account if needed

Helpful tip

When you speak to support, quote this exact error message:

“This username may be incorrect. Make sure you typed it correctly. Otherwise, contact your admin.”

It will help them get you to the right support team more quickly.

Since you were able to reset the password but still get the “username may be incorrect” error, the issue is likely with the account setup itself rather than your credentials. The best next step is to contact your company’s Microsoft 365 administrator or BT support, as they can confirm whether the account is still active, ensure it’s properly associated with your domain, and help restore access.

I've waited until I've had a free day because I figured this was going to be a long job. I've just been in connect with BT Support through the help desk no. Whilst they could identify my email account, we couldn't get past their first verification step as the business name they have registered for my email address on their system does not match my company name. The person I was talking to, tried to be helpful but we came to an impasse. I'm going to try the on-line support, see if they can help guide me.

I have had the same issue. It's rubbish that you can answer all the security questions but because you can't remember a post code from over 20 years ago, they won't help you. My wife is having the same email issues so something has been changed by BT over the last few days
