Bug: "Specified method is not supported"

Emclient keeps giving me this error when I sync. (i’ve replaced my actual email with my@email.com)

Log:

This is my university email account which uses office 365.

Hi Tom,
if your email account is office 365 it should be set up as Exchange account, not Airsync.
Could you try setting up your account manually as Exchange in Tools > Accounts and click New account > Mail > Exchange.
