How to Connect to Office 365
When integrating a calendar with the One Touch Dial application, the application requires permission to access calendar entries for participating devices, and allow the application to pass this information along to the devices. This allows the device users to join scheduled meetings easily with one click from the device's interface.
Note: There are two ways to connect to Microsoft Office 365; as an application or with a service account.
Application
When you connect as an application the One Touch Dial service is integrated into your Office 365 subscription as an authorized application.
This provides the One Touch Dial service with access to user and room resource account calendars in the organization. The One Touch Dial service will appear as an 'integrated application' in the Office 365 administrator portal where it can be removed at any time; thus removing access.
Note: You must be an Office 365 global admin of your organization to grant application access to One Touch Dial.
Service Account
A service account is an account which has been granted permissions to view a set of mailbox accounts. By using a service account instead of granting application access, you can maintain a higher level of control over calendar permissions granted to the One Touch Dial application.
Confirm the service account has the proper permissions to access each account you intend to use.
Note: The service account used is different than the user account used to log into the One Touch Dial application.
Compare
| Application | Service Account |
|---|---|
| Requires global admin consent. | Requires consent of only the service account. |
| Grants access to all calendars. | Can only access the calendars it has permissions to. |
| Managed from Office 365 admin portal. | Access tied to life of service account. |
| Easier and modern method of integration. | More fine tuned control of access rights. |
Note: Both methods use OAuth2 authentication to connect, which means you do not share credentials directly with the One Touch Dial application.
