Get MS Exchange mail for all group members

问题

Is it possible to get all email from all mailboxes in MS Exchange? I have full rights in Azure console for Office365 exchange online.

But when I'm trying make an request to

https://outlook.office365.com/EWS/OData/Users('user@company.onmicrosoft.com')/Inbox/Messages

getting an error "The specified object was not found in the store."

But for logged in admin

https://outlook.office365.com/EWS/OData/Me/Inbox/Messages

https://outlook.office365.com/EWS/OData/Users('admin@company.onmicrosoft.com')/Inbox/Messages

works well.

What should I do, to get access for read mail for all my users in office 365?

回答1:

The current authorization model for Office 365 Mail, Calendar and Contacts services does not currently expose a permission that would allow your app to query other users' mailboxes.

回答2:

The REST API consent flow allows you to register a web app that requires Admin consent. Once your web app has been given the global admin consent, it should be able to access information for all users under that tenant.
