Potentially dumb question regarding Exchange 2007 and Outlook 2016 RRS feed

  • Question

  • Hear me out...!

    We recently had Exchange 2010 installed alongside our existing 2007 environment (coexistence I guess). User data has not yet been migrated, so it's still sitting on Exchange 2007 mailbox databases.

    Here's the dumb question part...

    Although I know that Outlook 2016 doesn't work with Exchange 2007, I can't find any information - none whatsoever - on if it works at all in a coexistence environment. So my question is: If a user mailbox is still on 2007, but mail flow is being controlled by 2010, will Outlook 2016 work or will I still get the "unsupported version of Microsoft Exchange" error?

    The reason I ask this unorthodox question is because my boss seems to think that it will work due to Exchange 2010 being able to do some kind of pass-through. I've never heard of this and I doubt it's supported, but I'm no Exchange expert so I wanted some second opinions.

    Thanks in advance!

  • Nope, you would still be accessing the 2007 mailbox.  What are your CAS servers running on 2010 or 2007?
