Bear in mind, the process you need to follow is; 1. The easiest way to do this is simply connect to Outlook Web Access, and query the GAL directly (OWA uses the GAL no the OAB like Outlook running in cached mode does). The User/Mailbox IS listed on the Server But NOT in Outlook. Make sure the OAB you are looking at, has been updated from the GAL. If using Outlook, query the GAL directly, or download the latest OAB. Before you do anything send the user you created a ‘Test Email’ from your own account.In Outlook 2010 and previous, it is recommended to leave the option “Full Details” enabled.In Outlook 2013 and Outlook 2016, you’ll find that this option is no longer available as full details are also used to build the Contact Card.They do for my colleague sitting next to me, so I don’t think it is a server misconfiguration or something like that.Is there any way I can force a manual update of the Offline Address Book (OAB) in Outlook or reset it completely otherwise?
The command for the manual update procedure can be found here: Outlook will automatically download updates only unless the size of the changes is larger than 12.5% (one-eighth) of the total OAB size.In that case, it is recommended to recreate your mail profile.When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.This is called the Offline Address Book and is being generated on the Exchange server.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.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.
