Today Amazon WorkMail launched support for the MAPI over HTTP protocol for Microsoft Outlook for Windows. This protocol improves connection stability between Microsoft Outlook and Amazon WorkMail. This provides users a faster overall connection to Amazon WorkMail, and a more responsive experience.
Microsoft Outlook 2016, Outlook 2013, and Outlook 2010 with the latest service packs will automatically switch to the MAPI over HTTP protocol the next time they are opened. Users with Microsoft Outlook 2007 will continue to connect to Amazon WorkMail using the RPC over HTTP protocol.
