Subscribing to Team Calendars from Microsoft Outlook Does Not Work

[Buki Main Long]

Hi there,

I've been trying to connect our Confluence Team Calendar from Confluence to my Microsoft Outlook 2016 app. I've followed the step-by-step instructions listed here:

https://confluence.atlassian.com/teamcal/subscribe-to-team-calendars-from-microsoft-outlook-251005307.html

It has you download and install a plugin for Outlook called the CalDAV Synchronizer. I’ve installed this and followed the instructions, but keep getting met with errors.

The included screenshot shows the settings I choose when using the subscribe button in confluence:

 

The https://uisapp2.iu.edu/ is the url that you are directed to input into the CalDAV Synchronizer settings.

Here is a screenshot of my settings in CalDAV. When I press “Test or discover settings” I should be met with a list of available calendars with this connection info, but instead I get “No resources found”.

If I go ahead and hit “Ok” and save the profile, an error report is generated. Here’s a screenshot of that and I’ve included a raw text version of that report as well in case you would like it. It is below this screenshot.

I noticed there are several questions similar to this, but I have tried everything I can think of, including the step-by-step walkthrough. Just a few specific questions...

Is it possible the base url that we are being provided by confluence is incorrect?

Is it possible that our CAS authentication is causing a problem? If so, what would the work around be?

The two-way sync would be great to utilize if possible would simplify things greatly for us.

Thank you for your help!
