Hello, Sometimes when I create a user account on a server, which is mail enabled, it takes very long until that users mailbox is replicated within Exchange. Which proces is it that makes this happen? Is that the recipient Update Service? And how does that work? Is there a pre-specified time setup before a users mailbox is created after creating a user? When i look in the user account I see that the emailadresses are there, but I can not logon to OWA. Or do I first need to open the mailbox with an Outlookclient before OWA can be used? When I try it again now I see the following: I created 2 users. Both the same options. User1 and User2. First I created User1, I cannot open OWA. It keeps getting back with the passwordscreen, But User2 can open OWA!! Strange?!?! Mark
