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.
It's been about 15 minutes now, and it still does not show up.
How can I PUSH the updates to the laptops from the server?
You’ll find the following 6 oab-files in this location which make up the full Offline Address Book: If you are still using Outlook 2002/XP or previous, the file names won’t have a “u” in front of their name.
You’ll have to rename them all to or, in the case of Outlook 2010 or Outlook 2013, rename the folder containing the oab-files to to reset the local Offline Address Book.
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.
There are various Registry settings available to control or modify the update and download behavior of the Offline Address Book in Outlook.Use Cached Exchange Mode but without OABTo always work with the Online Address Book, even when you have Cached Exchange Mode enabled, you can set the following Registry key and value.Key: All Users or any other object type such as All Contacts, All Groups or All Rooms.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).not the best solution perhaps but the only one i know of.
