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?

Answer 1

Office 365邮件，日历和联系人服务的当前授权模型当前不会公开允许您的应用查询其他用户邮箱的权限。

Answer 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.
