Outlook global address list not updating
Users have correct login UPN in AD, but I have tried both @contosoint and @contosoext UPNs. "autodiscover.contosoext.com" resolves to Exchange server IP. SRV records and forward lookup zones created for OWA and autodiscover.Outlook Anywhere is enabled and I've tried both NTLM and basic authentication, as well as forcing basic authentication by manually configuring server settings in Outlook.I'm not sure what to do as having to fix machines manually including mail profiles for multiple users will be to many as there's heaps of staff affected.My problem was the virtualdirectories of the OAB, when I searched in powershell for "Get-Offline Address Book -identity Your OAB | fl *virtual* i received the following: Virtual Directories : And that "Exchange Back End" was my problem, changed it to "Default Web Site" restarted the IIS Service, gave it some minutes and then it finally worked!
However, I'm very stuck, and even my co-workers aren't sure what's going on here.
They can access OWA, and they appear in the OWA address book.
For existing users running Outlook 2013, the new users do not appear in the Global Address List nor in the "All Users" address list.
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.
