End of Outlook 2007 Support


Earlier this year we said goodbye to our friend, Exchange 2007.  Now that it is October the 10th, Outlook 2007 is also exiting out of extended support.

Customers who use Office 365 will have noted that there is a change to the supported client connectivity methods.  Outlook Anywhere is being replaced with MAPI/HTTP.  Outlook 2007 does not support MAPI/HTTP, and as such will be unable to connect.  There are many other reasons to upgrade so while we may look back on Outlook 2007 with fond memories, it is time to move on.

Office 2007 brought us Outlook 2007 which was a welcome change from the 2003 version of the product.  Some features are still with us, others not so much, for example Autodiscover and the ribbon interface are still firmly entrenched.  Looking back at the feedback from the introduction of the ribbon is quite interesting 10 years down the line…

Outlook 2007 will transition out of support on the 10th October 2017, as noted in its entry in the Microsoft support lifecycle.

Please ensure your users have been migrated to a supported version of Outlook.

    It is a shame that Outlook 2007 is no longer supported.

    I am curious about your comment, “Looking back at the feedback from the introduction of the ribbon is quite interesting 10 years down the line…” How is it “quite interesting”?

    1. Hi Ian,

      Regarding the “interesting” comment — take a look bat on the Internet timeline sites and look at the comments when the ribbon was first introduced. That’s what I’m referring to.

    Hello,
    I ask the same question on TechCommunity, if 1 November I can download mail from my O365 on Outlook with the protocol that Outlook 2007 uses now, and the reply is that the protocol is no more supported but I can continue, with my risk, to download and use a software that it is not supported.

    So the question is: Microsoft doesn’t support the client but doesn’t drop the functionality or I have an Outlook 2007 unusable (or better, only with impa/pop3)?

    1. Hi Marco,

      Leaving aside the question for a second, remember that Microsoft strongly recommends that a version of Office on mainstream support is used. At this time that is Office 2013 and 2016. While you may be able to connect with a client that is not in mainstream support, you will likely run into issues. This is in the Office 365 system requirements and here as well:

      You really want to be working with an Office client that is no longer receiving security or functionality updates?

      Back to your question:

      This is from message MC85988 in one of my test tenants:

      October 31st, 2017, Exchange Online mailboxes in Office 365 will require connections from Outlook for Windows use MAPI over HTTP, our new method of connectivity and transport between Outlook for Windows and Exchange.

      In May of 2014, Microsoft introduced MAPI over HTTP as a replacement for RPC over HTTP. RPC over HTTP was a legacy connection protocol that is being deprecated from Exchange Online.

      How does this affect me?
      Beginning October 31, 2017, Outlook for Windows clients using RPC over HTTP will be unable to access their Exchange Online mailbox.

      Cheers,

    I don’t understand, why so late. Goodbey and good riddance!

    1. Hi Jefferson,

      The standard support life cycle was used by Outlook 2007; 5 years mainstream and 5 years extended support.

      Cheers,

    As a simple user – I really do not know what all this means other than. of course, the fact that this will result in pain in trying to upgrade.

    1. Yes – it is time to upgrade Ian. Best to start on that right now.

      It means that the underlying protocol used by Outlook to connect to Exchange Online is being removed.
