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.

In order for some GAL entries to show up properly you may need to turn off Cached Exchange Mode.

outlook offline address book not updating-29

Hoping there is something in outlook 2013 that I can use to fix this or something in exchange.

When changes occur within the main Global Address Book (GAL) on the Office 365, computers running Outlook 20/2016 may not automatically receive the updates.

Seems like it takes a full day before the 2013 outlook users are up to date.

I have tried to manually download the offline global address list and this does not work either.

Check out Microsoft's FAQs for Office 365 (https://support.office.com/).

Microsoft also has some great training videos you can watch to become familiar with using Office 365 applications. : Martina Please remember to click “Mark as Answer” on the post that helps you, and to click “Unmark as Answer” if a marked post does not actually answer your question.This can be beneficial to other community members reading the thread.Step 3: The new version of the GAL will now be downloaded.A status window will open to indicate that the download is in progress and will close automatically when the download is complete.Do send/receive settings affect automatic 24-hour offline address book downloads?
