Exchange takes 24 hrs to Generate new users emails & appear in GAB

Hi

I have 6 exchange servers around the world that I manage without too many problems. But for some reason my Califonian Exchange server takes up to 24 hours before a new user appears in the GAB and to generate an email address for that user. Looking at the post from other people in this forum, I would put it down to oab only being generated once every 24 hrs, but in my case, I generate the address book every 3 hours and my other exchange servers all generate and publish new users in the GAB in the space of a few minutes and they also create the email address in the same time frame so it seems that this problem is specific to this one server I need to get this one sorted within the next 8 hours which is when my US users come online

Sounds like RUS may be taking a while to stamp the account. When you create the new account assume on the DC in CA then that needs to replicate via standard AD replication to UK site where RUS is running. RUS can then stamp the mailbox and replication will finally send this info back to the local DC in CA. After all this time the user will be able to logon and added to the GAL. If the DC in CA is a global catalog then I would suggest adding another instance of RUs in the CA or North America site depending on your replication and site setup.

Is this a single domain and single Exchange organisation? Are the new accounts created on this server stamped with an address etc in a normal time frame? Are the new users able to logon to their mailboxes on this server straight away?Where is your RUS running?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Version information would be nice.

Exchange version, service pack and patch level
Windows version, service pack and patch level.

Is there a domain controller with the machine in CA?
