Error Code: ResourceNotFound Error message: Resource could not be discovered.

Question

I am using this MS-Graph tutorial and while calling "List my inbox" I am facing this pesky error, Error code: ResourceNotFound
Error message: Resource could not be discovered. I researched a lot, and checked previously answered similar questions but no luck, could you please help? FYI "display access token" is working totally fine.

p.s. I am using a self created outlook account for testing purposes (looks like a personal account), its not a work/school account.

Hi @parth ,

Generally this error - "Resource could not be discovered" - occurs when users are not assigned with license or the mailbox is not configured for them.

Please check and confirm if there is a mailbox present/active in the Outlook account you are logging in with.

As mentioned in the referred document you need to have a personal Microsoft account with a mailbox on Outlook. com

Hope this helps.
