Companies running Exchange Server on their own premises often find their contacts stuck on that server. Getting the same contacts into cloud mailboxes, phones, CRMs or partner systems usually means manual exports, CSV imports and duplicate cleanup, and the copies go out of date quickly. Hybrid setups and migrations to Microsoft 365 make this harder, because contacts end up split between on-premises and cloud mailboxes. This connector keeps Exchange contacts automatically in sync with your other tools. Changes made on either side are picked up and applied without duplicates, and you don't need to install any software on your server.

How does it work?

The Exchange On-Premises Contacts connector links the contacts stored on your own Microsoft Exchange Server with the other apps your team uses. You can sync contacts from any personal contact folder, a shared or delegated mailbox, or a public folder, either one-way or two-way. Connect Exchange with Microsoft 365, Outlook, Google Contacts, iCloud, or your CRM. Every person then has the same up-to-date names, phone numbers, emails, addresses and photos. SyncPenguin's no-code rules let you choose which contacts sync, how fields map, and what happens when contacts change or are deleted.

Things to note

• Up to 3 email addresses are synced per contact, which matches the number of email slots Exchange provides.
• Exchange stores one number per phone type (for example, one mobile and one home number), so if a source contact has several numbers of the same type, the first one is used.
• Up to three addresses are synced per contact: home, work and other, which matches Exchange's address fields.
• Contact groups (distribution lists) are not synced. Only individual contacts are synced.
• Outlook user-defined custom fields are not synced, but you can combine extra information into fields like Notes using custom rules.
• Your Exchange Web Services (EWS) endpoint must be reachable from the internet so SyncPenguin can connect to your server.
• The contact creation date can be used in filters and rules but cannot be changed by syncing.
• Contacts in the Deleted Items folder are not synced.

Frequently Asked Questions

Which Exchange Server versions are supported?

The connector works with Exchange Server versions that have Exchange Web Services (EWS) enabled, such as Exchange 2013, 2016, 2019 and Exchange Server Subscription Edition. Your EWS endpoint needs to be reachable from the internet.

Can I sync contacts from Exchange public folders or shared mailboxes?

Yes. You can choose a contact folder in a public folder, or sync contacts from another mailbox that your account has delegate access to. This makes it easy to share one company contact list with everyone.

Can I sync Exchange On-Premises contacts with Microsoft 365 or Outlook?

Yes. You can set up one-way or two-way syncing between Exchange Server and Microsoft 365 or Outlook contacts. This is useful for hybrid environments and for moving contacts to the cloud gradually.

Will syncing create duplicate contacts?

No. When you start a sync, you can choose to merge existing contacts on both sides first. After that, SyncPenguin tracks each synced contact and only applies new changes, so duplicates are avoided.

Do I need to install anything on my Exchange server?

No. SyncPenguin is a cloud service that connects to your Exchange server through its standard web services, so there's no software to install or maintain.

Does Microsoft's EWS retirement affect Exchange On-Premises syncing?

Microsoft's planned EWS retirement applies to Exchange Online in Microsoft 365, not to Exchange Server installed on your own premises. Your on-premises Exchange contacts can continue to sync through EWS.

Can I sync only some of my contacts?

Yes. You can pick a specific contact folder and add no-code filters based on categories, company, email domain or any other field. Only the contacts you want will sync, in each direction.
