OAuth2 Microsoft MailboxNotEnabledForRESTAPI Error

Nievelungen

After some debugging i found out that if i use the Graph API not the Outlook Api and give Access to the application with our admin account, i get an access token for our admin account and not the account that i wanted to embbed.

This seems to cause issues, since now i have the wrong User.

When you authorize try signing into the email itself to authorize the scopes.

This only work if the user has consent rights if there is another Admin User to consent the request it returns the wrong user.
This promt in the URL thing breaks the whole thing, since it would only needed to be added once for MS stuff.

Ok so i found out that the Plugin adds '&promt=constent' to the URL which basically breaks the whole flow.
If removed it works perfectly fine.
Also quick word from my sysadmin purposefully adding the 'promt=constent' to the URL can cause consent loops in the Auth Server which is pretty bad.

Nievelungen Yeah that works for me too.
But i see, in the Token tab, the token expires in +/- 1 hour. Or is that a normal thing?

Trust me, we know. This is why we are going to make it configurable in the future.

Cheers.

Yeah JWT Tokens expire normally in 1 Hour, but the Plugin gets a new one when the old one expires (With the refresh Token).
This is default OAuth2 flow.
At least for me it works fine and the Plugin gets a new one automatically.

Nievelungen Ok, thx for the reply. I'll check this in 1 hour.

Hi, I've tried many great suggestions and still facing the same issues. Just cannot proceed from here. I can confirm that I am using a microsoft 365 account and not an exchange account.

Hi ramrajone , thanks for your reply. I saw the link and follow all the steps. I keep getting

array('code' => 'MailboxNotEnabledForRESTAPI',''message'=>'The mailbox is either inactive,soft-deleted, or is hosted on-premise.',)

Not sure what i need to test or what logs to look for ? Any help will be appreicative.

That's an error most likely due to consent, double check and make sure you have given correct permission and also clear cache of your browser

Hi ramrajone , thanks for all your help. I went back to check on my App Registration in Azure and discover i was creating it in a wrong Directory or Domain. After switching to the right directory .. it is working. Thanks for your help. 😃
