By default, when you mail-enable a user, that user will be given an e-mail address that matches the user’s online services id. You can always add other e-mail addresses, using Exchange Control Panel:
As you can see, it is not possible to change the primary e-mail address using this Exchange Control Panel, when you change the user its online services id, the primary e-mail address will match the new online services id… so:
Is it possible to change the primary e-mail address of a user without changing it’s online services id?
Yes, by looking here:
You can see that by using the Exchange Shell, it’s fairly easy to change the primary e-mail address without changing the Microsoft online services id.
And, yes there is…using the Exchange Management Console
You can install the Exchange Management tools on a Windows 7, as described here: Install the Exchange 2010 Management Tools
After installing the required windows components, I am ready to Retry:
When launching the Exchange Management Console, I get an error that he is unable to connect to an On Premises Exchange environment, but I can right-click and select Add Exchange Forest:
And chose to select to Exchange Online:
And there I can see the mailboxes in my Online environment:
When going to the properties of my mailbox, I can select the tab E-Mail Addresses,
click on firstname.lastname@example.org, and click Set as Reply:
Time to test:
Primary E-Mail address has changed, and the Online Services id hasn’t
Excellent article, will be very useful to the community, congratulations
I'd be interested in using the Exchange Management Console, but as an Office365 subscriber only, I don't have an installation CD from which to pull the Management Console. Is it available elsewhere? I can't seem to find a straight answer.
I second Thomas's comment as I'm in the same situation. On Office 365 without a CD to install the Management Console with, can it be downloaded somewhere?
You can download the complete Exchange DVD here: www.microsoft.com/.../details.aspx. You have to go through the entire install process, selecting only "Management Tools" during the custom install.
