AquaMail is an email app for Internet and Exchange mail, for Android 2.1 and higher.
Easy automatic setup for popular email services: Gmail, Yahoo, Hotmail, FastMail, Apple mail services (@me.com / @mac.com), GMX, AOL, and more. Recognizes mail accounts at domains hosted by Google Apps, Yahoo BizMail, and others.
Works with many other email services via standard Internet email protocols (IMAP, POP3, SMTP) as well as Microsoft’s EWS (Exchange Web Services) protocol.
Microsoft Exchange is supported via IMAP or EWS. EWS includes access to server side contacts (personal and global, with lookup), and accepting meetings that can later be viewed in Outlook and other apps.
Easy automatic setup for Office 365 and Exchange Online.
Push mail for IMAP (instant incoming email delivery) for those servers that support the IDLE extension (Gmail, GMX, AOL… not supported by Yahoo).
Plays well with other email apps that you may be using to access your IMAP or EWS mailbox. Uses existing folder structure, can synchronize drafts, sent, and deleted messages.
