Free live horny chatroom - Outlook global address not updating

When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.

This is called the Offline Address Book and is being generated on the Exchange server.

Due to various synching schedules, it can take up to 48 hours before you could actually see a change in Outlook after a modification has been made on the Exchange server or in Active Directory.

This means that in the worst possible scenario, an update to the Address Book won’t become available to the user until 48 hours after the change.

This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.

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.

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.

In a later section, it is explained how to modify this.

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.

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.
