I have seen comments and notes about losing the ability to send/receive emails to and from your helpdesk from Microsoft 365 due to changes in security at Microsoft. Here is a quote from an message from Sean at SpiceWorks: “In addition, as we communicated last year, both Microsoft and Google are making improvements to the security of email mailbox authentication. These changes will make GSuite and Office 365 mail services unusable by users of the Desktop 7.5 application. Following deadline extensions from Microsoft and Google because of the COVID-19 crisis, there are currently no published firm dates for the final “cut-off.” But Microsoft and Google have already begun the transition for new email accounts, and they appear to be targeting a complete transition later in 2021” Here is a link to that message:
