Hi,
The problem we're experiencing is that:
1) User is created in AD
2) Log on to Exchange Admin Center and attempt to create a mailbox for the user, the user cannot be found for approx. 15 minutes.
The above problem is intermittent. Yesterday I had to wait 15mins but today I can find the new user straight away.
When I had the problem yesterday I was still able to create a mailbox for the users in Exchange Management Shell so the problem is specific to EAC. This leads me to think that it is a problem with EAC. I cannot see any issues with AD replication, I'm creating the users on a domain controller in the same site as the Exchange servers.
Any ideas on what may be causing the delay?
Thanks
