Hi, I am trying to get my Outlook 2013 synced to a Synology CalDAV service. Testing the connection works fine with the following URL: http://192.168.x.x:x/home/calendarname/
But when syncing, your tool seems to expect a specific folder structure or files on the server, which doesn't exist:

So what is your tool looking for? Do I have to create any specific file or folder?

Any help is much appreciated. Thank you, Thomas

Hi,

The timeout seems to happen in some cases.
Currently it is not clear, which communication partner blocks the communication and I am working on a solution.

Please see Ticket #50 https://sourceforge.net/p/outlookcaldavsynchronizer/tickets/50/ for more information.

We fixed some timeout issues by properly disposing WebRequests. Please try 0.99.8
