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

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.

You can back up or copy that file elsewhere if you want to keep the list or use it on a different computer.

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.
