SBS2011 to ws2016 & Exch2016 migration
I would greatly value some advice on re-establishing remote (mobile & Outlook) access to Exch2016 again. Remote & internal access via OWA *is* working and Outlook 2010 appears to connect internally.
Unfortunately, I'm a bit late to this party, for many reasons - budget, users preferred SBS-features, etc., and had wanted to perform a trial migration of the SBS2011 VM, on my home test server, but it couldn't cope (memory, etc.). Therefore I've migrated the real server whilst the users are vegetating whilst watching Christmas TV programmes.
