Microsoft have recently announced changes to Office 365 which will impact on email connectivity for those using Outlook 2007. The RPC over HTTP protocol which Outlook 2007 leverages to make the connection to Office 365 is being deprecated on October 31, 2017.
To continue to access your email through Outlook, you must upgrade to a client that uses the more modern MAPI over HTTP protocol. Versions that will continue to function after October 31 are Outlook 2010, 2013 and 2016.
If you are using one of these versions of Outlook, you should ensure your email client is running with the latest updates installed (pictured above). For Forsythes Managed Service clients, these updates will already be deployed as a part of our regular maintenance and patching. For those who have not upgraded to a later version of Outlook, you may continue to access your email through web access and mobile devices. This change will only affect Outlook for Windows connecting to Office 365.
Outlook 2007 – RPCing ya later!
