EMclient just updated itself to version 9.2.168, and now when I try to send an email it says “no account has been set up”. This is the case with both New emails and Replies. I have two accounts, both of which are receiving emails. (And were working fine before the update)
Please go to Menu > Accounts and click on the General tab for the account.
Scroll down to services and tick the AirSync option. Click on Save & Close.
