Hey all, just touched base with AirMail support team and there is a very easy fix for this!
Just delete the account from AirMail and then re-add it as an IMAP account.
Use the settings specific to your email, but for me (outlook/live accounts) the server info was as follows:
IMAP server address: imap-mail.outlook.com
IMAP port: leave empty to auto detect
SMTP server address: smtp-mail.outlook.com
SMTP port: leave empty to auto detect
I hope this proves useful to some of you. :)CFitz commented
Also having this issue with multiple @outlook/@live accounts.. Was working just fine until about a week ago. Pretty frustrating to have to open the web clients for those emails just to send emails from them!
