The Global Address List in Exchange On-Premises is only fully available inside Outlook while connected to your company's server. Employees often can't see coworkers' details on their phones, in Google or iCloud contacts, or in business tools like CRMs. Keeping those contact lists updated by hand is slow and full of mistakes, and it gets worse as people join, change roles or switch departments. SyncPenguin solves this by automatically copying your Exchange address list to the apps your team uses and keeping it current.

How does it work?

The Exchange On-Premises GAL Contacts connector lets SyncPenguin read your company's Global Address List, or any other address list, directly from your Exchange Server and share it wherever your team works. Automatically copy coworkers' names, job titles, departments, companies and email addresses into Outlook, Microsoft 365, Google, iCloud or your CRM. Your company directory stays available and up to date on every device and app. Filters and no-code rules let you choose exactly who gets synced and how each field appears.

Things to note

• This connector is read-only by design. It reads contacts from your Exchange address list and syncs them to other apps, which protects your company directory from unwanted changes. To edit directory entries, update them in Exchange as usual and SyncPenguin will pick up the changes.
• The connector syncs each person's primary email address. Additional email addresses, phone numbers and postal addresses are not included at this time.
• Custom fields are not supported. The connector focuses on the core directory details: names, job title, department, company and email.
• You need to provide the ID of the address list you want to sync. Your Exchange administrator can find it in a few seconds using the Exchange Management Shell.
• Your Exchange Server must be Exchange 2013 or newer, and its Exchange Web Services (EWS) endpoint must be reachable from the internet so SyncPenguin can connect securely.
• Each sync reviews the full address list to find changes. Very large directories may take a little longer to process than smaller ones.

Frequently Asked Questions

Can I sync the Exchange On-Premises Global Address List to my iPhone or Android phone?

Yes. SyncPenguin can copy your GAL into Outlook, Microsoft 365, Google or iCloud contacts. These sync to your phone automatically, so coworkers' details are always in your phone's address book.

Is the sync one-way or two-way?

The Exchange On-Premises GAL Contacts connector is a one-way source. Contacts flow from your Exchange address list to other apps, which keeps your official company directory safe from accidental edits.

How do I find my address list ID?

An Exchange administrator can run 'Get-GlobalAddressList | Format-List Name,Guid' or 'Get-AddressList | Format-List Name,Guid' in the Exchange Management Shell. Copy the Guid value of the list you want to sync and paste it into SyncPenguin.

Can I sync only certain employees, like one department?

Yes. SyncPenguin's no-code filters let you include or exclude people based on department, job title, company, email or any combination of fields.

Which Exchange Server versions are supported?

The connector works with Exchange Server 2013 and newer, as long as Exchange Web Services (EWS) is reachable from the internet.

Will syncing create duplicate contacts?

No. SyncPenguin's sync engine tracks every synced contact and can merge with existing entries during the initial sync, so your address books stay clean.

What happens when someone's job title or department changes in Exchange?

SyncPenguin detects the change on the next sync and automatically updates the contact in every connected app.

About Exchange On-Premises GAL

Microsoft Exchange Server is Microsoft's self-hosted email, calendar and contacts server, used by organizations that run their messaging infrastructure on their own premises. Its Global Address List (GAL) and custom address lists act as the official company directory. They contain names, job titles, departments and email addresses for everyone in the organization, and are available to users in Outlook.
