That said, I recommend moving off Entourage to OS X Mail or Outlook 2011 for Mac. The platform also works with recent versions of OS X's integrated Mail, Calendar, and Contacts applications.Įven older shops still running Entourage 2008 Web Services Edition should find the platform compatible, although such offices should expect to have to make Entourage configuration changes, including changing the Exchange account settings, as described on Microsoft's Office Online site. Microsoft's Office 365 Business Essentials plan, which scales to support up to 300 users, is compatible with Microsoft Office 2011 for Mac. For $5.00 (USD) per user, per month (paid annually), you'll be challenged licensing, installing, administering, maintaining, and securing your own email server - regardless of platform - for less. It's hard to beat Microsoft's Office 365-hosted Exchange email services.
