Exchange -> Office 365 -> username issue

[mdrabble]

Couple of years ago, we had a user called careers1 which was later renamed to a proper username eg. JBloggs

 

They logged on to the network using JBloggs and their on premise exchange mailbox was set to [email protected]

 

Just migrated the user to Office 365 and it have set the Office365 account name to [email protected] and I can see no way of changing this!!!

 

Anyone any clues how I can change the office 365 name back to jbloggs?

 

Cheers

Add the other email address as an alias

Also change the attributes so careers@ proxy starts with a SMTP and the name@ starts with SMTP and don't forget to change email address in advance as well Richard

In the attributes of AD, make sure the primary email is SMTP and aliases have smtp. The capitals make all the difference

If you mean the 365 logon ID rather than email address, it will match the on premise UPN of the user, so double check this (on the same tab as the pre-win2000 logon name in AD User Properties).

 

If they don't match you need to run the following in powershell:

 

Connect-Msolservice (then put in admin creds for 365)

Set-MSolUserPrincipalName -NewUserPrincipalName [email protected] -UserPrincipalName [email protected]

All AD and Mailbox settings were set to the correct username JBloggs with Careers1 set as an mailbox alias

 

I've been through the AD Attribute editor and can see no mention of Careers1

yep tried all that and I get access denied due to being sync'd to premise

Odd, works for me and ours were originally migrated from exchange on premise to 365. New accounts were created on 365 but via whatever AD sync is called these days.
