Hi,

maybe you already heard, POP(S) and IMAP(S) access to O365 account will be rejected from 2021 September from by Microsoft side. The ServiceDeskPlus only support POP IMAP and EWS connection to reach mailboxes. EWS is already outdated by Microsoft so there is no option to download client letters to make tickets from them. Have somebody setup a mailbox connection to O365 service in any other way then IMAP POP or EWS?
