Global address book not updating
I've been doing enterprise IT for about 8 years and have never had to ask a question in a forum, because you lovely folks had already answered all my questions for other people.However, I'm very stuck, and even my co-workers aren't sure what's going on here.
This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.I feel like the most likely culprit was a Windows update gone bad, so I've removed recent updates, and that didn't do anything, so now it is fully patched. How about restart Microsoft Exchange information store service, Microsoft Exchange System Attendant service and Recipient Update Service? Moreover, check the event log in Exchange server and monitor the connection between GC and Exchange.I'm hoping someone has seen these symptoms but had a resolution outside of these troubleshooting steps. Due to various synching schedules, it can take up to 48 hours before you could actually see a change in Outlook after a modification has been made on the Exchange server or in Active Directory.In this guide, the relevant timings are explained and instructions are given in how you can directly force an update and resync, which can be very handy when troubleshooting or when you work in an Exchange environment which sees a lot of user mailbox mutations.
On the Exchange server, the new users appear in the "All Users" address book when running "Preview" in Edit Address List wizard (EMC All Users) I can run "Update-Global Address List -Identity "Default Global Address List." Command runs successfully with no errors generated.
