Publish MS Outlook 2013 calendar online via WebDav server?
In order to synch my MS Outlook 2013 calendar with outside parties/tools, this is an available option - publish calendar online to a WebDAV server. It asks for the location of the 'custom server' to do as such. Is this something feasible with a Group plan? If so, how? What might be that address? I tried to load an address I figured might be it, and got Outlook to ask for the user name/pw, but then states it can't confirm the link, etc. (or something like that) and it gets no further.
Any help or a point in the right direction helpful!
