Owa global address list not updating
Maintained by your IT department and stored on the Exchange server, the GAL usually contains names, addresses and email information for everyone in your organization with a company email address.
If your company is moving from Exchange to another email system, or if you want a quicker response time when addressing emails, you can also add items from the GAL to your locally-stored contacts folder in Outlook. Highlight all the entries that you’d like to export to your local contacts folder.
Using cmdlets like those below will save you time, more so when you realize that every Exchange 2007 configuration task has a faster command-line equivalent.
Furthermore, certain commands are ONLY available in the Shell, for example, new-Global Address List.
How It Works: On a scheduled basis, Epicenter Server synchronizes a copy of the GAL to a contacts folder in each user's mailbox. During installation, you configure Epicenter Server by telling it which address book to distribute, who should receive the address book, and how often to send updates.
Then Active Sync synchronizes those changes to each user's device. The address book could be your Exchange GAL, an Exchange address list, or an Exchange Public Folder.
If your company hosts its email system using Microsoft Exchange, you have the benefit of a centrally-managed address book called the Global Address List, or GAL.
Additions, deletions and changes are automatically applied to keep contacts up to date.
No additional software is required on the phones or tablets.
Either leave the configuration alone, and just let Outlook users see the Default Global Address List; or else, take the time to study, plan, and test before you implement custom Address Lists.
Default Address Lists (See Screenshot right) Once you realize that there are a handful of built-in Address Lists, you soon realize that you could create your own Custom Address Lists.
