How do I delete old e-mail logins from the Outlook credentials login when hooking up to my exchange?

Hi there,

A friend of mine has recently switched over hosted exchange services. He uses 2 exchanges and they are set on different profiles. When he hooks into Exchange A, the correct username shows up and offers him to sign in with either of the two emails he uses with exchanges.

When he hooks into Exchange B, he gets the following in the dropdown list, email for Exchange A or an old email credential he used to use once upon a time for the email associated with Exchange B. He has changed hosted exchange service and this is on a new profile.

Any ideas?

Below is an illustration as such:

Exchange A Profile:
                                 E-Mails in login box: Exchange A and Exchange B as a choice

Exchange B Profile:
                                E-Mails in login box: Exchange A and old login for Exchange B but not new credential for B

Any ideas would be greatly appreciated.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is there a reason there are 2 different instances of exchange? or there is just one but Outlook(i assume your using outlook??) thinks that there is 2(the old and new)

There are 2 different exchange accounts, 1 on each profile of Outlook.
Control Panel/User Accounts, click the Advanced tab, and then click the Manage Passwords button.  If there are any passwords stored here, delete them.


rundll32.exe keymgr.dll, KRShowKeyMgr

NOTE: back them up first before you delete them

SOrry the client was away MegaNuk3 you are a genius! Thanks that worked a treat. I had to re-add the credential afterwards!

Thanks for the update and the points.

BTW - here is a slightly quicker way of opening the "Stored Passwords" window:
Start->Run->type "Control keymgr.dll" (without the quotes) and press Enter

It is easier to remember the other line I gave you.
