 ## When will it be ready for production?
-Well, not yet. Though it does sort of work already.  
+It works for non-Microsoft email clients now (see Compatibility above).  
-I'm working on this ultimately for my own use for my own small business. I'm hoping once it's good enough I could deploy the set up to my businesses customers and ultimately get them away from a Microsoft Exchange based environment. There's a long way to go for that right now though.  
+Outlook's autodiscover is a troublesome little blighter, MailAutoConf does generate a valid Autodiscover.xml, but modern Outlook clients use an Autodiscover.json file now which isn't documented anywhere. I'm working on this and hope to get Outlook Compatibility as soon as possible.

+Then it's down to Autoconfiguration of Calendars and AddressBooks... but that's down to the email client developers really...
