As a response to What is Outlook synchronizing now?, the following was asked;
In which order does Outlook synchronize the folder when it is configured in Cached Exchange Mode? Can I configure this order?
There is indeed a specific order in which Outlook synchronizes the folders when you are connecting to an Exchange server with Cached Exchange Mode enabled.
While you can’t directly change the sync order, you can still influence it by selecting the folder that you want to have synched.
Once Outlook is started and the cache has been updated, the synchronization is taking place based on timers and not on folders. This provides a near instant update mechanism.
Folders are first synched in a specific order and then kept up to date by timers.
Folder Synching order
|15||Public Folder Favorites|
|*||By default, the selected folder is the Inbox.|
|**||Remaining folders are ordered by Outlook by using an intelligent learning algorithm that identifies which of these folders are used more frequently.|
Note: When Outlook is placed in “Work Offline” mode and you initiate a manual send/receive (keyboard shortcut F9), the currently selected folder does not have an affect on the synching order. So if this is a non-default folder, it will be treated as a “User-created folder”.
