Plaintext access is no problem if the connection is secured via other means - for example internal network or VPN.
If the IMAP server cannot be accessed from the outside, and the traffic don't travel over wifi or public networks, no danger.

Curious, what's the rationale behind that move? Is it because that old beast of Outlook does not have the capabilities modern TLS/STARTTLS implementations require regarding TLS minimal version and ciphers?

But plaintext auth for mail access, seriously?
