Configuring itrezzo Contact Management with Azure AD
We recently worked with a customer that had 3000 mailboxes in their Office 365 GAL. The Unified Contact Manager, our unified contact management tool, was using Exchange Web Services and GAL sync was failing miserably.
We wanted to fall back to LDAP since they were running DirSync. Unfortunately, there were three different domains from different locations syncing into Office 365. Each of them had a unique copy of their local GAL. Office 365 had the only complete master copy of all GAL entries.
That is the point where we switched their GAL access type to Azure AD. Things worked perfectly after that.
If you want to Sync the Office 365 GAL to a smartphone, this post explains how and why you might need to use Azure AD.
Office 365 Global Address List Types
- If you have DirSync to on-premise AD, you can configure LDAP.
- The default method to sync the Office 365 GAL is Exchange Web Services (EWS).
- For an Office 365 GAL with more than a few hundred users, an ideal solution is to use Azure Active Directory. Microsoft provides access to Azure AD through the Graph API.
Setting up the Office 365 Tenant to use Azure AD
You may need to click the gear icon in the top right corner of the grid to get Active Directory to refresh.
You can also create a collection. When you try to search the GAL to add members to the collection, it will now use Azure AD. If this fails, Azure AD is not properly configured.
To diagnose failures, open the logs for the current day of the week. Scroll to the bottom of the ECO log. It will have some errors messages. Look for the Azure error result. If you can’t resolve this on your own, feel free to contact itrezzo Support.
