Office 365 – How to update the Global Address Book in Outlook

When changes occur within the main Global Address Book (GAL) on the Office 365, computers running Outlook 2010 and 2013/2016 may not automatically receive the updates. If this is happening, then you may notice missing, non-existent and/or incorrect entries. Synchronizing your Outlook (cached) address book with the Global Address book may fix these discrepancies. Instances of mail that is bounced back to the sender may also be fixed.

Please use the steps below to update your Global Address Book.

In order for some GAL entries to show up properly you may need to turn off Cached Exchange Mode. Please visit the document on How to turn on or off Cached Exchange Mode for (Outlook 2010, and Outlook 2013 and 2016).
