Updating gal exchange 2016
If the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.
In that case, you can completely reset it by deleting the files making up the OAB or by recreating your mail profile.
I might have a problem with my Offline Address Book in Outlook.
For me, new colleagues are not showing up and the contact pictures aren’t displaying either.
*** NOTE: The GAL is essentially a real-time / online representation of AD Objects that are Mail Enabled for Microsoft Exchange *** The GAL contains information for all email enabled users, Distribution Groups, and Shared Mailboxes and Exchange Resource Mailboxes.
Users not receiving latest contacts in cached mode UPDATE GLOBAL ADDRESS LIST USING EXCHANGE MANAGEMENT SHELL (EMS) NEXT OPEN EXCHANGE MANAGEMENT CONSOLE (EMC) BY DOING THE FOLLOWING: 1. Locate your Default Offline Address book and Right Click on it then select Update.
Another way to make sure that you get a fresh copy of the OAB is by renaming the oab-files to when Outlook is closed.
