Outlook requests credentials that are not mine

Outlook 2010
Exchange 2010

I have previously added another persons email account to my outlook 2010, when Outlook started it understandably requested both my username and password and the other accoounts. I have since deleted this account but the login box that appears still has the other accounts info filled in and requests for that account credentials? How can I get rid of this? Tried uninstalling outlook and re-creating profile.

Buried in Control Panel> Manage Credentials, you should find the credentials that you are prompted with - simply delete the credentials and they won't appear again.

Perhaps I'm thinking too simple but did you try 'use another account' and then tick 'remember my credentials'?
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Go into registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Exchange

There are several profiles for your Outlook. Some of them contains REG_SZ keys like this:

/o=your_domain/ou=Exchange Administrative Group/cn=Recipients/cn=your_mailbox_name
/o=your_domain/ou=Exchange Administrative Group/cn=Recipients/cn=deleted_mailbox_name
and some profiles doesn't have any of these keys.

Delete all profiles which contain other (deleted) mailbox name keys.
PeteAuthor Commented:
No, a reg entry for the deleted mailbox does not exist.

I actually tried deleting the entire 'profiles' folder from that reg path, it prompted to recreate the profile, which I did, but the same log in box with the other user as default appears.

Did you change permissions on the other mailbox in order to give yourself full access? If so - try to remove these permissions on your Exchange.
PeteAuthor Commented:
no i didn't. I am an exchange admin.

Are you sure you zapped all the relevant credentials from the Credential Manager?  It usually works for me.
PeteAuthor Commented:
sorry alanhardisty, that was indeed the correct place, I just didn't look properly.
