Microsoft Graph me/messages API return message "Access to OData is disabled."

Question

Why am I getting an error when all permissions have been agreed?

Answer 1

Hello @佐藤 浩二 This issue may be due to ApplicationAccessPolicy. Administrators can limit third-party app access to only that set of mailboxes by creating
an application access policy for access to that group. Here is the documentation:
https://learn.microsoft.com/en-us/graph/auth-limit-mailbox-access
https://learn.microsoft.com/en-us/powershell/module/exchange/get-applicationaccesspolicy?view=exchange-ps

Hope this helps.

I'm setting Set-OrganizationConfig -EwsApplicationAccessPolicy: EnforceAllowList for another reason.
What should I set for Microsoft Graph if I have to use EwsAllowList?
