I'm about to migrate our Exchange 2010 servers to 2016, but wondered about something. I read that versions of Outlook older than 2010 SP2 (with hotfix) can't connect to Exchange 2016 (see at the bottom of https://technet.microsoft.com/en-us/library/aa996719(v=exchg.160).aspx
). Is this true only if the user's mailbox is hosted in an Exchange 2016 database, or even if the mailbox is stored in the old 2010 database?
In other words, can older clients, like Outlook 2010 (no SP installed) connect to a mailbox stored in Exchange 2010 through Exchange 2016?
Thank you so much for your answers!
