Outlook 2007: How to Get Rid of a Default E-Mail Address


A client of ours uses Outlook 2007 on a Terminal Server.  When he opens Outlook, the "Connect to outlook.office365.com" window that appears defaults to an e-mail address.

This produces an error to where the client cannot get into Outlook.  The only way around this error is to hit the drop-down list in that window and for the client to choose his own e-mail address.

So, what steps need to be taken to remove the default e-mail address that prevents getting into Outlook?

Is he still using outlook.office365.com?  If not then you can remove it from the email account settings.

Go to Account Settings... from the File > Info. menu
Highlight the desired default account
Click Set as Default
Remove the outlook.office365.com

Note you cannot remove outlook.office365.com if it's a default email account. You need to set another as default first.

Hi Wayne88:  There is no "Info" menu in File.  In any case, when I do find the desired default account, the "Set as Default" button is greyed out.

Hi David Johnson:  I cannot find the key that you suggest to delete.

Thanks, for the quick responses, nevertheless!

Hi Wayne88:

I tried this, and "Set as Default" is greyed out.

Hi TBSupport,

Set default will be greyed out if:

You didn't select (highlight) another email account then set as default
You don't have another email account

Can you provide a screenshot of what you see?

Hi Wayne88:

Attached is the screenshot.

Thank you!

Hi TBSupport,

Is that account your Office 365 account?  If yes then it's the default account since you only have one account on the list.  It won't be possible to not use it as the default sending account without adding a new one then making it default email account.

Also, in the future please blank out your company name in the screenshot or any sensitive information.  I've asked moderator to edit or your attachment.

TBSupportAuthor Commented:
Thank you, and I'll be more mindful, in the future.

Still, the problem remains.  When the end user first opens Outlook, he sees a different e-mail address by default and has to change it to his own e-mail address.

Please help me eliminate this problem.

Thank you.

Assumptions remote desktop  session based
you installed office using the
change user /install
During installation, select Customize, and then clear the user name and initial values or use  a config.xml file that has the user name and initials set to empty values.

After installation, remove the values from the registry key HKLM\Software\Microsoft\WindowsNT\CurrentVersion\TerminalServer\Install\Software\Microsoft\Office\Common\UserInfo.
change user /execute
each user has a separate login account.

if you didn't use the change user /install  and change user /execute you have to reinstall the software.

Hi David:

I think that your registry setting is wrong.  I cannot find it.  Can you repeat, please?

Hi TBSupport,

I think it's easiest to do it this way because we aren't sure why your Outlook is giving different email address when there is only one account:

Let's make a fresh start:

- Backup all the user's email.  If the all the user's emails are in Exchange then you have nothing to worry about but it's best to back them up just to be safe.
- Go to the user's computer, make sure Outlook is not running then delete the user's email profile.  Follow this instruction on how to delete it.
- If there is more than one profile then delete the other profiles except for the current user's then open Outlook again and the different email address(es) should be gone.  If not then proceed to deleting all the profiles then go to the next step.

Recreating the mail profile and Outlook account

- Recreate the user's profile by following the instruction in the previous link and click the "ADD" button instead of remove (there should be nothing to remove).
- In the Profile Name box, type the name (e.g. "New Profile") that you want to use for the new email profile, and then click OK.  Make sure the dropdown selection is set to always use the profile you just created (in this case it's "New Profile")
- Proceed with recreating the Exchange email account in Outlook then once done you will see that Outlook will start syncing the emails with Exchange.
- Close then reopen Outlook, you shouldn't have any other default email address except for the one you just created for the user.
