I have used Outlook for Mobile until now. But I have set up a new domain and I can’t add my account to Outlook - there is a years’ old bug that won’t let you add an IMAP account unless it has a weak password (i.e. no special characters). I’m not going to weaken the security on my IMAP account just for Microsoft’s poor programming.
What is a good alternative email app (no, I won’t use GMail!)?
