Export to PDFTo connect to the destination, you can choose to only use a service account, Fly app profile, or custom app profile as the authentication method. You can also use the combination of a service account and a Fly app profile, or the combination of a service account and a custom app profile.
Refer to the following sections to view the permissions required by the authentication methods.
With the Tenant Owner or Service Administrator role, you can create a Fly app profile in AvePoint Online Services > Management > App management to connect to the Microsoft 365 tenant using the Fly app.
Refer to Fly App Profile Permissions about how to create a Fly app profile and required permissions of the Fly app profile.

*Note: You need to assign the Exchange Administrator role to the AvePoint Fly app in the following situations. Refer to How to Assign the Exchange Administrator Role to an App? or instructions.
If you do not want to assign the Exchange administrator role to the app authorization user, you can add custom roles to the app to ensure the availability of above functions. Refer to How to Add Custom Roles to an App? for details.
With the Tenant Owner and Service Administrator role, you can create a custom app profile in AvePoint Online Services > Management > App management to connect to the Microsoft 365 tenant using a custom Azure app.
Refer to the following procedures to create a custom app profile:
Prepare a certificate in Microsoft Entra ID. Refer to for more information.
You can ignore this step if you have a certificate.
Create a custom Azure app in Microsoft Entra ID. Refer to for more information.
