Outlook gal is not updating
If the key name doesn’t exist, Outlook uses a value of 8.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.And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).The command for the manual update procedure can be found here: Outlook will automatically download updates only unless the size of the changes is larger than 12.5% (one-eighth) of the total OAB size.In that case the whole OAB is being downloaded again.
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.

Some of those contacts have been added to my personal contacts list in outlook.
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.
