Hi,

 

There are issues with the OAuth V2 protocol with personal accounts (outlook.com / hotmail.com) when using the EWS API.

It seems like the access_token is not a valid JWT token as it should be, https://monosnap.com/file/yd7uHNFJRMFxHFy8J6jqYckGiy8uEr

 

There is an active issue on GitHub since last year: https://github.com/OfficeDev/ews-managed-api/issues/229

 

I don't understand how this migration will work if the protocol does not yet support for personal accounts.

BTW - The official Microsoft Outlook email client is still using Basic Authentication with personal accounts.

 

To be clear, it does works with an Office365 account but not with outlook.com/hotmail.com accounts.

 

I hope to get an official answer to this issue.

 

Thanks.
