Admin simplified - say hello to
Easy admin control with 3CX and Microsoft 365
3CX makes managing your phone system with Microsoft 365 simple. User accounts sync automatically, creating extensions without extra effort. Logging in with SSO is secure and easy with Microsoft credentials, reducing password issues and cutting down on helpdesk requests.
Call recordings and backups can be stored directly in SharePoint, keeping everything organized in one place and utilizing storage you've already paid for. With Teams Direct Routing, 3CX bridges the gap between Teams and your phone system, allowing users to call between platforms. This setup reduces daily admin tasks and ensures smooth low maintenance operation.
Use the email integration to send out email notifications using MS 365 and eliminate notifications potentially ending up in spam folders.
Let users work seamlessly
Allows users to stay connected within M365. Avoid missing important calls or messages by launching calls directly from M365 with the 3CX Windows Desktop App and Click2Call. Your users can work with synced contacts, calendar updates via 3CX apps.
Leverage storage already paid for!
Make use of storage you already have. Automatically store call recordings and backups in SharePoint, for a centralized, accessible and secure solution for essential data. See our SharePoint for Backups and Recordings guide for setup help.
Direct routing with Teams
Connect 3CX and Teams to streamline calls between platforms. Bridge Teams and 3CX users, cutting costs by limiting Teams licenses to key users while keeping most on 3CX. Note: 3CX-Teams Integration is not a Teams PBX replacement.
Your Microsoft 365 integration questions answered...
For easy calling you can have personal 365 contacts synced to the 3CX personal phonebook. You should note it’s a one-way synchronization so all contacts need to be managed and updated from Microsoft 365. You can also do the same for Microsoft 365 shared mailbox contacts and sync these to the 3CX Company phonebook - giving easy access to all. All contacts in the default folders: “Well Known Folders” are also synced. In practical terms you’re now able to call your 365 contacts directly from the 3CX Web or mobile apps.
Yes no problem! 3CX is user-friendly enough for your IT team to handle on their own. Host your 3CX on Amazon, Amazon Lightsail, Google and Digital Ocean. Deploy direct via their marketplaces. Or opt for 3CX Hosting and have us manage your system for you.
Yes. 3CX supports Microsoft 365 Single Sign-On (SSO), allowing users to log in with their Microsoft credentials instead of a separate 3CX username and password. This simplifies user management and improves security by centralizing authentication through Microsoft Azure AD.
