The Global Address List is the most complete and accurate source of colleague contact details in a Microsoft 365 organization. However, it is often unavailable where people need it most: on mobile phones, in personal contact lists, in other apps or in partner organizations. Keeping these copies current by hand is slow and error-prone. Partners, subsidiaries and merged companies on separate tenants also struggle to see each other in their address books. This connector keeps directory data flowing automatically, so contact details stay consistent everywhere without manual exports or scripts.

How does it work?

The Microsoft 365 GAL Contacts connector brings your organization's Global Address List into SyncPenguin. It includes employees, guest users, organizational contacts and groups. You can automatically sync your company directory to Outlook, Microsoft 365, Google or iCloud contacts so everyone has up-to-date colleague details on their phones and devices. You can also sync contacts from CRMs, other tools or another Microsoft 365 tenant into your GAL as mail contacts. SyncPenguin's no-code filters, field mapping and custom rules let you control exactly which people are synced and how their details appear.

Things to note

• Users and groups are managed in Microsoft 365 and synced from the GAL only. Contacts synced into the GAL are created and updated as mail contacts, which keeps your user accounts safe from accidental changes.
• Each GAL contact holds one primary email address and one work address, which matches how Microsoft 365 stores directory contacts.
• Groups are synced as single entries with their name, email and description. Their members are not expanded into individual contacts.
• Group memberships, office location, user type, account status and profile photos are available for syncing from the GAL only.
• Custom fields are not supported. All standard directory fields are available for mapping.
• Country names written to the GAL must match the country names recognized by Microsoft 365. Unrecognized values are skipped, and all other address details are still saved.
• Newly created mail contacts can take a few seconds to receive all their details, because Microsoft 365 needs time to register the new contact.
• Connecting requires a Microsoft 365 administrator, and creating or editing GAL contacts requires appropriate Exchange admin permissions.
• Loading profile photos is optional and can make syncing slower in large directories.

Frequently Asked Questions

Can I sync the Microsoft 365 Global Address List to my iPhone or Android phone?

Yes. You can sync the GAL to Outlook, Microsoft 365, Google or iCloud contacts. Your company directory then appears in your phone's native address book and stays updated automatically.

Can I sync GALs between two different Microsoft 365 tenants?

Yes. Connect both tenants in SyncPenguin, and users from one tenant are created as mail contacts in the other, one-way or both ways. This is ideal for partner companies, subsidiaries and mergers.

Can I choose which people from the GAL are synced?

Absolutely. You can include or exclude members, guests, organizational contacts and groups. SyncPenguin's no-code filters let you narrow it down further by department, office location, group membership, account status or any other available field.

Will SyncPenguin modify my Microsoft 365 user accounts?

No. User accounts and groups are synced from the GAL only. When syncing data into the GAL, SyncPenguin creates and updates mail contacts and leaves your users and groups untouched.

Are profile photos and group memberships included?

Yes. You can optionally include user profile photos, and each user's group memberships are available for syncing or for filtering.

What do I need to connect my Microsoft 365 GAL?

A Microsoft 365 administrator needs to authorize SyncPenguin, either by signing in or with an app registration. To create or edit GAL contacts, the account also needs Exchange admin permissions.

Does the sync keep running automatically?

Yes. Once your sync is started, SyncPenguin regularly checks your directory for new, updated and removed entries and applies the changes according to your rules.
