I am unable to connect to Office 365 Outlook to send custom mails to users. I get the error "Please check your account info and/or permissions and try again. Details: You are not authorized to perform this operation. This error can occur for sandbox (test) accounts or if OData operations are disabled by your Exchange server administrator. clientRequestId: a8eef7f7-5217-497a-b1ce-a213109fd9a2-self".
I am able to use othher connectors including Office 365 Users etc.
My IT team has no clue what may be wrong.
