Attempting to subscribe to a public calendar, I get the following text in an alert message box:  "There was an unexpected error with the request on subscribed calendars (error -1)."

 

I can subscribe to the same calendar successfully from a Windows 7 PC with Outlook 2007. Does anyone have ideas on what I may be running into? Even a slightly more informative error message would be helpful.

    I was having this same issue when trying to subscribe to an ICS file on a web server. After lots of messing around with things, I discovered that the server was not sending the correct content type in it's response headers.

     

    I added the custom mime type "text/calendar" for files ending in ".ICS" to the server's configuration (luckily this is a server I have control off) and it works fine for me now.

     

    It looks like Calendar requires the mime type / content type to be:

    Content-Type: text/calendar

     

    You can check the content-type your server is providing in it's headers at the following site: http://urivalet.com/.  Just paste the URL of the ICS file you are trying to subscribe to and scroll through the headers to see the value for "Content-Type".  Let the server administrator know if it needs to be changed to text/calendar for *.ics files.

     

    Good luck.
