Options for connecting to Office 365 Calendar

There are two ways to connect to your Office 365 Calendar:

  1. You can connect using an encrypted Exchange Web Services (EWS) connection.
  2. You can connect using an encrypted OAuth 2.0 connection.

Connect using an encrypted Exchange Web Services connection

OnceHub communicates with your Office 365 Calendar using the Exchange Web Services (EWS) API, a well-established official Microsoft protocol. All credentials and data traffic are fully encrypted. Learn more about how your sign-in credentials are stored and protected by OnceHub

You can connect to your Office 365 Calendar via EWS with your Outlook email address and either a password OR an app password

When you connect to your Office 365 Calendar via EWS, you connect by using your Outlook email address and password, as you would normally log into your mailbox via Outlook or any other method.

When you connect to your Office 365 Calendar with an app password, you are permanently authenticating the OnceHub platform with your Office 365 Calendar. App passwords never expire, which ensures that OnceHub will connect to Office 365 continuously and without interruption.

Connect using an encrypted OAuth 2.0 connection

When you connect to your Office 365 Calendar with an encrypted OAuth 2.0 connection, OnceHub does not store your password. Instead, a token generated by Microsoft is used to communicate with the Office 365 API.
