Does this mean that Outlook 2007 will not function with O365?

    I have one client that in the upgrade path but that is not scheduled until January 1 of 2018. Is anyone absolutely certain that Outlook 2007 will no longer work with O365 even if all the proper updates are applied such as SP3 and some other KBs?

     

    I just need to make sure it absolutely will be cut-off on October 31st.

     

    Thank you!
