Our company is moving to Office 365 and does not allow POP or IMAM on the Exchange server. Is there any way to make Thunderbird access the emails on the Exchange server using the MS proprietary protocols? I've been using Thunderbird for 20 years and migrating all my email archives to Outlook seems like a major pain.
