I have no experience with AD nor with Exchange server but have been tasked with setting up a SP online intranet for a company using Azure AD and office pro plus and have their own on prem exchange server.
Although i am able to get some user and group details within the SP online, i cannot do some things and would like advice;
using Power Automate fails with The request failed. Error code: 'InvalidApprovalCreateRequestAssignedToNoValidUsers'. Error Message: 'Required field 'assignedTo' contained no valid users in the organization'.
