We are running Exchange 2010. All of my thin clients (Office 2007 - WinServer 2008) and my few PC laptops (Office 2007 - Win7) aren't able to find any recent users that have been added into the directory. One is just a mailbox I've created for a new conference room, and the others are new employees. They do not show up in the global address book and also don't appear when typing in the name and clicking the "Check Names" button.
However, all of my mac users are able to find these users no problem and book time in the new conference room. When I login to webmail and check names, it is able to find the new mailboxes just fine. Any suggestions of what the problem may be would be great! Thanks!
