How can I integrate my existing outlook accounts with my office 365 subscription?

[tahir khan]

Hi,

I am a little confused on this. When I try to create a new office 365 tenant, the users get created in the following fomat, ex:

tahir@companyname.onmicrosoft.com

And when I open the Mail tab from the App launcher, a new outlook account gets created for the user. I don't wish to do this rather I am in a need to utilise already existing outlook accounts for my organisation for all users.

Any help on this would be highly appreciated.

Every customer gets one of those companyname.onmicrosoft.com addresses to match their tenant name but you can bring in your custom domain, so you can use whatever email address you require, to match your brand, company name etc.  These are the steps involved -  Add a domain and users to Office 365.

And to add to Ciam's comment, if you have an existing e-mail service where your users have all the e-mails, you have to plan for migrating e-mails, contacts and calendars to Office 365
