Changes are coming in how Outlook connects to Office 365

This October the 31st not only marks the well known holiday that is Halloween but it also marks the date when Microsoft removes the support for RPC over HTTP aka Outlook Anywhere from Office 365 (Exchange Online), this will have a profound affect for some users who are not on the latest version of Outlook.

What does this mean?

So what exactly does this change mean and how will it affect end users? Let’s break it down to into the different versions of Outlook.

Outlook 2007

After the 31st October 2017 anyone still using Outlook 2007 will not be able to connect to Office 365 and will ultimately need to upgrade to a newer version.

Outlook 2010

Anyone using Outlook 2010 will still be able to connect to Office 365 but only if the build version is 14.0.7164.5001 which was released in December 2015.  It’s also worth noting that Office 2010 is now out of mainstream support and extended support only runs until 2020.

Outlook 2013

Outlook 2013 users will still be able to connect to Office 365 as long as they are running build version  15.0.4779.1002, which again was released in December 2015.

Outlook 2016

This version is unaffected by the changes on the 31st October 2017.

How do I find out what version of Outlook I am using?

If you are unsure about the version of Outlook that you are running you can refer to this Microsoft support article.

Are mobile devices affected?

No, this change does not affect Outlook on Android, iOS, Windows 10 Mobile or the Web App.  This change only applies to how Outlook on Windows connects.

Does this change affect IT departments running Exchange on premises?

If you are still running Exchange 2007-2016 on premises then this change does not affect your system or end users. But running older versions of Outlook may impact you in the future if you decide to migrate to Office 365.

54 days

October 31st 2017 is only 54 days away, so don’t delay check your environment and ensure you can still connect to Office 365 when the changes are implemented.
