Outlook cached exchange mode not updating
In Cached Exchange Mode, Outlook 2007 & 2010 downloads a local copy of the Global Address List (GAL), but only updates it every 24 hours.In order to reflect any changes or updates made to the Global Address List, you can force Outlook to download a new copy of the GAL.
And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).The order in which it does this depends on your version of Outlook (see the table below).While you can’t directly change the sync order, you can still influence it by selecting the folder that you want to have synched.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).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.
Key: Note: As Outlook 2010 an Outlook 2013 can connect to multiple Exchange servers in a single mail profile, there is an additional “Offline Address Books” subdirectory which contains folders with GUID references which contain the actual oab-files.
Finding out which GUID represents which mail account isn’t very straightforward but looking at the “Date modified” value of the folder should give you a good indication if you don’t want to simply delete all folders or rename them to
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.
When the value is set to 0, Outlook will use 16 to prevent a “divide by 0” error.
