Office/Outlook 2016 Compatibility Issues with some Exchange Server setups
Does not affect basic POP or IMAP email account setup.
Microsoft removed the option to manually configure exchange accounts in Outlook 2016. Setup requires that a domain has auto-discover records.
This means that in some situations setup of existing exchange email accounts may be difficult or impossible. Primarily these issues are related to non-private domains - ie. If you use an ISP or shared email setup eg. @vodafone, @clear.net.nz, @xtra)
Please check with your Exchange email provider if you are upgrading to Office/Outlook 2016
