IMAP on O365 now requires “Modern Auth”, which requires OAuth to authenticate access to mailboxes. Anything that connects via IMAP will need to be approved by the admins at this point (Including Thunderbird). Without the cooperation of your organization’s IT team, you are not going to get far.
I see this said every time this comes up.
Are there any efforts starting or even attempting this? Or even taking an existing printer and replacing it’s main board?
