If you are not seeing correct contact information in the GAL for someone that has a valid email address (i.e.

So there are three factors stopping you seeing that new user on the GAL (, however if that’s not an option, read on). Force your Outlook Client to Download the Offline Address book. Check that the OAB is getting distributed from the Exchange/CAS server. Note: Make sure the Generation Server is set to a server that exists, and it’s online.

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.

For instance, setting the value to 4 will trigger a full download when the incremental update is larger than one-fourth the size of the full OAB.

When you update an Offline Address Book on the Exchange server via the Exchange Management Console or the Exchange Management Shell, one would suspect that updating the Outlook client after that would directly get you this fully up-to-date copy. After the OAB gets updated on Exchange, it still needs to distributed to the web services first, even in a single server environment.

The process of updating and distributing the OAB is achieved by the following two schedules.

The Global Address Book (GAL) is a directory of available contact information for CUMC, NYPH and Columbia University faculty, staff and students.

It can be accessed when using a CUMC email account with Outlook and Web Outlook.Renaming just a single or some of the files will result in an OAB corruption. A benefit of manually deleting the oab-file is that before they are being re-downloaded, you are working with the Online Address Book.When you find things working correctly for you now but not anymore after the oab-file were redownloaded, you know that the issue is with the oab-files on the server and not on the client or the Address Book configuration in general.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).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.
