Ok, this is going to be a tough one to explain. Here is the environment:
User has 3 email addresses
Windows 7 64 bit machine
IE8 - 32 Bit and IE864 bit
Exchange 2003 and outlook 2007
The computer is part of a domain.
User used to be able to go to the OWA and it asked for his credentials. Which worked flawlessly. He would use his Outlook 2007 for his main email address and then log into OWA to work in his other email boxes. Then last week, when he would go into OWA, it quit asking him for his credentials and automatically brought up his main email box (one he has configured in Outlook 2007).
What we have tried:
-We have cleared out all the the cache and cookies and history. And rebooted his computer...did not change anything. Same problem.
-We have gone into IIS and removed the check box for the Integrated Windows Autheentication on our exchange server IIS properties. That worked, but then all of our smartphones quit updating their email (about 330 smart phones).
-Added the email box at the end of the owa URL. this allowed him to get into that email box (still did not ask for credentials...just put him into that email box). So, he was able to see his email and receive it. But, he is not able to send any email from that account...which is very important.
-It is only on his computer, as when I go into thsoe email boxes through OWA on my computer, all functions properly.
- One thing special about this account is that his email address and login to the secondary email addresses have diferent login names then his email address.
-We also added those email address profiles to his outlook, but he is an executive...so...he can't quite get the execution down to change his email address when sending emails from the 3 different companies that the email addresses represent. And that is TOTALLY important to keep all those separate, as we are a dealer for 1 brand of truck. But, we are the main distributor for another brand of niche micro truck where we want to get dealers to sign up to sell these niche micro trucks. Since they would be a competitor in our larger truck market, if they knew we also were a dealer for the competative larger truck market, they may decide not to be a dealer for the smaller niche market trucks.
Any help would be appreciated quickly, as execcutive is traveling the next 12 days.
