Have been in touch with the support team, waited several times for changes to take effect after 48 hours, but still no joy.
It's been a month now!!!

Having ongoing problems with email for a domain, let's call it COMPANYB.co.uk, that I transferred in to BT a month ago.
There was already an existing domain, COMPANYA.co.uk
I don't think the mailboxes have been activated/set up correctly...
... The backend of BT Business Email Lite package is managed by them through an Exchange setup?
Emails to any of 3 specified addresses bounce back to sender as underliverable with error
550 5.1.10 RESOLVER.ADR.RecipientNotFound; Recipient [name@COMPANYB.co.uk] not found by SMTP address lookup
and when trying to log in to emails through the office 365 portal at
"Your account or password is incorrect." or "Unknown user"
Manage Services, Manage Email Accounts
Business Email Lite
The mailbox for COMPANYA (primary user) is Active (no problems with emails for this domain)
The 3 mailboxes for COMPANYB are (now) listed as Active
Here are the zone configurations in btdomainmanager.com
CNAME mail mail.btconnect.com
A * 188.8.131.52
A * 184.108.40.206
CNAME autodiscover autodiscover.outlook.com
TXT @ MS=ms00000000 (EDITED)
MX @ COMPANYB-co.uk.mail.protection.outlook.com 1 <------
TXT @ v=spf1 include:spf.protection.outlook.com -all
The MX record for working COMPANYA looks different?
<------ MX @ COMPANYA.co.uk.mail.eo.outlook.com 10
You're best speaking with the support team again to let them know that you've waited 48 hours with no solution. Do the mailboxes appear to be registered on the BT Business portal and are you able to log in with those mailboxes using this website? If so, it sounds like an issue with the mail server and the second line team can check if the mailboxes have been configured correctly via their Office 365 tenant access.
If management tasks are affected by the move requests, follow these steps:
Connect to Exchange Online by using remote Windows PowerShell. For more information, see Connect to Exchange Online using remote PowerShell.
Verify that the mailbox is being moved. To do this, run the following command:
If the "Display Name" placeholder matches the mailbox for which you want to enable or disable archiving, a mailbox move is in progress. The move is preventing the change from being made.
Examine the output, and then do one of the following, as appropriate:
If the Status is Queued or InProgre, wait for the move to finish. This should occur in one or two days. If you can't
