Checking ther reason of [Status Code: NotFound; Reason: REST API is not yet supported for this mailbox.] while subscribing to resource mails

I tried to subscribe to resource Users/xxx/mailFolders('Inbox')/messages and got error Status Code: NotFound; Reason: REST API is not yet supported for this mailbox. I have found that user has licences attached to file.76244-lic.txt



One of them is EXCHANGE_S_ENTERPRISE. What name of licence should be for success subscribing?

I read that error also can occur if the mailbox is on a dedicated Microsoft Exchange Server and is not a valid Office 365 mailbox. How can I check from graph api if user has valid Office 365 mailbox?

The easiest way is to check with your administrator (who usually keeps track of the license) that you're using or you can try using the Get-Recipient Exchange PowerShell to get the same.

Thank you! But the question is what exact licence should be (name or names)? Or how exact we can detect valid o365 user for subscribing mails (exact param that we should find for user)?
