[ms office - o365] New Office365 Tenant already has users????

[fiza]

I am trying to set up an Office365 Tenant at Trust level (central services). We do not currently have one in any of our Schools or at the Trust Level. We all use Google everywhere and I am only really familiar with Google. For the Trust I have several domain names registered in .com, org.uk formats. Only one of these has Gmail MX records configured and all the rest are just domain names with no settings. When I created a new Office365 Tenant using one of the unused domain names and allowed the MS setup to configure the MX records, it completed successfully but listed 6 users. These users are people who work at the Trust but it makes no sense to me where it has got the names!!!

Can anyone shed any light on this please?

We've had similar and found some of the users had signed up for Teams by themselves but using the school domain name.

That sounds like it could be it as some of them do use Teams. The only thing that doesnt make sense is that they use the domain name ****.org.uk which is an acronym of the full name and I have a domain registered with the full name but they do not use that and it is not associated with any email addresses they use. Did the Domain Registrar or MS link the 2 somehow? The users only exist in the acronym version of the domain name.

 

Also as MS say they need to verify that we are an education domain, the users are all listed with @onmicrosoft.com addresses.
