Graph API permission issue to update Office 365 group settings via Application user(ClientId/Secret)
Hello Everyone, I'm facing an issue updating the allowExternalSenders setting for a Microsoft 365 Group. I've tried various methods, including granting permissions of App to Groups and Directorie...
Not every operation is supported for application permissions, afaik this property can only be updated via delegate permissions. If you need to use application permissions, Exchange Online PowerShell or the (unsupported) /adminAPI endpoint might be an alternative
- I have added some of the delegated permissions as well to this app. Also, Could you please give more details on the alternate ways?
- Delegate permissions work fine, check your token if you are still getting errors.
The alternative is to use the REST endpoint that the Exchange Online cmdlets use, the so-called /adminAPI. However, this method is not officially supported by Microsoft. You can find more details and examples here: https://www.michev.info/blog/post/3883/exchange-online-powershell-module-gets-rid-of-the-winrm-dependenceThank you for the explanation. I had try delegated permission, i still get the same error. Do u have any other way round for this?
