We recently had the IT Director leave for a different job. In doing so we had to change the administrator pass for the servers. Old: CompanyName\Administrator New: CompanyName\Services The new admin account was switched for all services that showed the old admin user was controlling. Changed the username to services, and restarted each service Then Restarted the Exchange Server all together. Since then we have started having users who have a windows authentication box pop up asking for you to login to Exchange.CompanyName.local .... I'm not an exchange guru, and thought we had covered our bases. Is there another area that we may have missed where the old profile admin needs to be changed to the new Services admin name? Thank you in advance for any suggestions.

nothing?

Hi,What is the version of your exchange server?If it is Exchange Server 2007,then I think you can try to delegate the Organization Adminstrator role to user.
