Setting up homestead's roundcube email in Outlook App

I was loving the ability to monitor my business email account on my Android Tablet, until the latest OS update removed my Outlook App. I've reinstalled it. Now I'm trying to set up my roundcube/homestead email on the App again, and its not taking it. Any suggestions for what I'm doing wrong? I wish I'd had the foresight to wrote down the settings I'd used on the tablet last time.

IMAP Incoming Mail Server

Host name:  imap.homestead.com:143

Username:  (my email address, all lowercase)

Password:  (my password)

SMTP Outgoing Mail Server

Host name:  smtp.homestead.com:587

Username:  (my email address, all lowercase)

Password:  (my password)

Seems all good to me, but the app keeps saying "This service is offline."
