Exchange 2016 not updating database
OAB Update schedule To change the OAB Update Schedule via the Exchange Management Console: Organization Configuration-Rather than changing the default schedule, you can also force an update and redistribution of the Offline Address Book.This is great for testing or when it is important that changes are published immediately (note that users must still update the OAB manually or wait a OAB sync interval to see the changes).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 the whole OAB is being downloaded again.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.Even though Outlook is the last in the chain, it is often the first level where the troubleshooting takes place as usually this is where the request is coming from.And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).
Firstly and fore mostly: If you do anything in Exchange: Apply the “cup of coffee rule”, never make a change then go and prove that change works straight away! However most of us work in the real world and you have a user who needs to use this mailbox yesterday! Then check the mailbox Exists (See Check for existence of mailbox sections below). Remember, if you are looking at the Global Address List in Outlook then you are NOT looking at the Servers Global Address List*.In addition to this there a a few methods by which your Outlook clients get the offline address book. Outlook 2003 (and older)* clients get their OAB from a public folder, Outlook 2007 (and newer) clients can get their OAB from ‘Web-based distribution’ (basically form the website on the Exchange (or Exchange CAS) server.So there are three factors stopping you seeing that new user on the GAL (, however if that’s not an option, read on). Force your Outlook Client to Download the Offline Address book. Check that the OAB is getting distributed from the Exchange/CAS server. Note: Make sure the Generation Server is set to a server that exists, and it’s online.Bear in mind, the process you need to follow is; 1. If you are using Outlook you may be in “Cached Mode”, and you are looking at a copy called the “Offline address book” This only gets updated Every 24 hours, and the copy on the server only gets updated every 24 hours at (by default). 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. The Mailbox SHOULD be in the right hand window (Providing you are in the correct administrative group, on the correct server, and in the correct mailbox store! Remember with Exchange 2007 / 2010 you create the mailbox with the Exchange system Manager anyway! On the Exchange Server, Start Ensure “Hide From Exchange Address Lists” is NOT ticked.
Also in the properties of the mailbox database, your users are using, make sure it points to the correct public folder database.
