Connect Microsoft 365 account with Yeastar Workplace

By integrating with Microsoft 365, your current and future events will sync with Yeastar Workplace on both web portal and Room Displays.

You can easily integrate room bookings from Yeastar Workplace web portal, room displays, and Microsoft 365 calendar. And manage all the room bookings efficiently through Yeastar Workplace web portal.

This topic describes how to connect your Microsoft 365 account with Yeastar Workplace as the first step of integration.


  • Yeastar Workplace can access the Internet.

  • Yeastar Workplace plan: Standard Plan or Pro Plan.

  • The Microsoft 365 account to be connected must meet the following requirements:

    • Admin role: Global Administrator

    • Microsoft 365 license: Business or Enterprise


      • To check and assign admin roles on Microsoft 365, see this topic.
      • To assign Microsoft 365 licenses to users, see this topic.
      Why is a global administrator account required?

      A domain-level "Enterprise App" will be installed to manage your room resources. This app will be installed for your entire organization, so you will need a global administrator to complete this step. If you'd like to understand more about why a Global Admin is needed, Microsoft has an explanation for this requirement.


  1. Log in to Yeastar Workplace web portal, click the account button in the top-right corner, and select Management Portal.
  2. Go to Integration, click Connect beside the Microsoft icon.
    In the pop-up window, log in with a global administrator account.
  3. Yeastar Workplace will ask for permissions to access calendar information in order to sync events. Click Accept to complete the connection.

Trouble shooting

If the followinmg page is displayed after clicking Accept, it indicates that your Microsoft 365 account doesn't meet the requirements for integration.

Now your Microsoft 365 account is connected with Yeastar Workplace.
On this page, you can view the permissions that Yeastar Workplace obtained from Microsoft 365.

Why does it ask for full access to all mailboxes?

Yeastar Workplace uses an authentication method called OAuth to securely install the app onto your Microsoft 365 account. OAuth is a way for apps to request very specific rights for your account. For Microsoft 365/EWS, Microsoft requires that all OAuth apps request mailbox permission for EWS API's. Once installed, Yeastar Workplace only interacts with your calendars.

What to do next

Once your Microsoft 365 account is connected with Yeastar Workplace, you can add rooms from Microsoft 365 and allocate devices.
