Outlook 2010 doesn't save password (Exchange)

Hello,

An issue with Outlook 2007 in combination with my Microsoft Exchange e-mail account was that it couldn't remember the password and I had to enter it every time I started Outlook. This was solved by adding a credential through 'control user passwords2', a workaround which can be found on several sites.

However, this doesn't seem to work anymore using Outlook 2010 with Windows 7. Or at least it seems to work different, but I can't get it to work. Outlook itself creates a generic credential in the form of MS.Outlook:<USERNAME>@<EXCHANGESERVER>UT, but on another website I found the form MS.Outlook:<E-MAILADDRESS>@<EXCHANGESERVER>UT
It also creates two Windows credentials, one with the username also as server and one with the correct exchange server, username and password.
What should I add to make Outlook remember my password?

I also tried some other workarounds for previous versions of Outlook, but they all didn't work. I tried these:
Stop Outlook/Outlook Express Asking For Your Password Every Time | Windows Vista | Windows Tools, Help & Guides
Outlook 2007 won't save passwords in Vista...save password..

Does anyone know how to solve this?

I have make the problem!

I try itself, it's ferry simpel. Open Outlook 2010.
Than comming the dialoog box whit your nickname and password.
Delete your nickname and password. So that is blank. Than click the "Remember password". And click on the "Save"button. And close Outlook 2010.
Than open Outlook 2010 again. Than is not show more the dialoog box.

Thats all.
