Default offline address list exchange 2016 not updating
Exchange 2013/2016 Exchange 2013/2016 will only be distributing the OAB via web-distribution. For all versions of Outlook (since 2003) you have two choices, either take Outlook out of cached mode* (so it queries the ‘live’ global address list).Or force Outlook to download the latest version of the offline address book. 24/02/13 If you create a new user, give them a mailbox, and they seemingly fail to appear then don’t panic! If you receive an error message then you can investigate further (Note: Set your Outlook client to send you a delivery report on the test email as well). 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.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*.When you find things working correctly for you now but not anymore after the oab-file were redownloaded, you know that the issue is with the oab-files on the server and not on the client or the Address Book configuration in general.
Prompt before for full download As the OAB can be quite large in some environments, it could be wise to be prompted when Outlook wants to download the full OAB.Key: All Users or any other object type such as All Contacts, All Groups or All Rooms.Full OAB download threshold To modify the threshold at which Outlook will download the full OAB rather than the incremental update, you can set the following Registry value Key: As the value, set at which relative size a full OAB download should take place rather than an incremental update.For instance, setting the value to 4 will trigger a full download when the incremental update is larger than one-fourth the size of the full OAB.When the value is set to 0, Outlook will use 16 to prevent a “divide by 0” error.
