I'm in a fairly protected professional environnement and I'm trying to publish my work calendar to OwnCloud using "Publish to WebDAV" option of Outlook 2013. I have ensured that OwnCloud is reachable through HTTPS from my Outlook machine and I can log into account from a browser (my OwnCloud is reachable through https://xxxx.ch/cloud type of URL). But I cant seem to find a proper way to enter OC credentials in the Windows 7 security dialog to go through…
But as I wrote in original post, my professional environnement is pretty locked up and no I cannot install any plugin to Outlook. I'm stuck with some basic option such as "Publish to WebDAV..."
And outlook is unable to directly upload into an owncloud calendar. With the function you mentioned, you just can upload to a .ics file, that you can share with others.
EDIT: This doesn't really work here. Outlook creates an initial ics file on owncloud, but without any VEVENTs inside.
It used to work with a free service on icalx.com. But that doesn't seem to maintained anymore Beside I was continuously having problems with recurrent events. I also would rather prefer to have my work agenda going to my own server than somewhere else…
