You have a set of Office365 credentials which permit you access to the services.
IMPORTANT : You need to know these and be able to use them on the portal
They consist of a username and a password.
Your tenancy name is appended to “onmicrosoft.com” as the full reference and we try and combine this with your first and last names to make your username.
So, for Fred Bloggs at Acme Corp the username would be FredBloggs@acme.onmicrosoft.com . Yes, this looks like an email address and you will receive any emails directed at it.
It’s also possible to allocate your own domain name as your email address. So if Fred has an email address of firstname.lastname@example.org then we could set that as the Office 365 username.
We prefer not to do so for the following reasons:
- Your company might have several domains, acme.com and acmeexplosives.co.uk for example so remembering which one is your Office365 username could be a problem.
- We automate some of our admin tasks using scripts and programs and having a standard username format makes this feasible
- Using your own domain name means logging on won’t work if there are any DNS problems. Just another thing to go wrong!
- People might not easily guess your Office365 username if they know your email address and are attempting to hack your account.
