Outlook 2007 connectivity to Office 365 ending in Oct 2017

Highlighted

Hey all. I wanted to give you a heads up on an upcoming deprecation in Office 365. On Oct 31, 2017, RPC/HTTP will be deprecated in Exchange Online in favor of MAPI/HTTP, a modern protocol launched in May 2014. Outlook 2007 does not work with MAPI/HTTP. This means that in order to continue email connectivity, Outlook 2007 customers will need to update to a newer version of Outlook or use Outlook on the web.

 

Additionally, Outlook 2010-2016 customers will need to ensure their version of Outlook for Windows is setup to support MAPI/HTTP. Minimum required versions are:

  • Office 2016 plus PU.2015.12
  • Office 2013 SP1 plus PU.2015.12
  • Office 2010 SP2 plus PU.2015.12
  • These updates can be accessed via the KB article located here

Customers may need to ensure their Outlook clients are not using a registry key to block MAPI/HTTP. Details about this registry key can be found in this KB article on our support site

 

The links here should have all the answers you need, but let me know if you have any other questions.
