I just spent the past 2 days attempting to find an inexpensive, simple solution for handling the Outlook calendar publish feature.  I'm running Office 2013 on a home computer (and not MS's Exchange Server)  According to MS, it simply requires a WebDAV server and that is what DriveHQ offers.  So I created a free account, and attempted to use a variety of addresses supplied by DriveHQ for one of my folders... none of the addresses are acceptable to Outlook.  Here's what I tried:

1) I published the folder's address using my browser and DriveHQ's online data management interface.  Outlook doesn't accept this as a valid address

2) I used DriveHQ's Drive Mapping Tool and used these addresses: E:\,     E:\DriveHQ_Dox,  and  \\(various numbers and letters).webdav.drivehq.com@SSL .  Outlook doesn't accept this as a valid address.

3) I read some forum topics on the issue from 2007, but they all addressed the issue via FTP, but Outlook demands a WebDEV server, not an FTP server.  One forum post by DriveHQ Webmaster suggested a workaround using DriveHQ FileManager, and publishing to a local server, but I have no separate computer to use as a server.

Can someone help me get this properly configured with some guidance on how to generate an acceptable WebDAV address?    Any help would be appreciated.

Well, I guess this could be called progress... I used a published address generated by DriveHQ FileManager and Outlook didn't tell me it was an invalid address.  It told me the "upload... failed.  The folder you are publishing to does not exist. Check the path to the folder, then try again."  Here is my published folder from DriveHQ FileManager (sans user name): http://www.drivehq.com/file/df.aspx/publish/(user-name)/MyDox .  Why would Outlook think the folder doesn't exist?

This is a very interesting feature. Outlook supports both FTP and WebDAV paths. However, the plain FTP path is considered to be less secure, and I don't think Outlook supports FTP over SSL. So let's focus on the WebDAV path.

To get the WebDAV path, it is recommended that you install our WebDAV Drive Mapping Tool first. You can then map a drive using our Drive Mapping Tool. After that, you can create a folder in your account, e.g. \FreeBusyInfo   (in your account's root folder).

After that, you can log on to www.drivehq.com website, then visit this page:

   https://www.drivehq.com/mapdrive/GetWebDAVURL.aspx

Your WebDAV URL should be like:   https://dhqid***.webdav.drivehq.com

Your publish location should be like:  https://dhqid***.webdav.drivehq.com/FreeBusyInfo/NAME.vfb. Please see the screenshot below:

Click OK to save it. Outlook will then publish your calendar information to the cloud folder every 15 minutes.

For users who are not familiar with the Outlook calendar's Publishing Free/Busy Info feature, Microsoft has a support page at:

Due to some compatibility issues with different versions of Outlook, we recommend users map WebDAV Drive as "Local" drive. Mapping a WebDAV cloud drive as a "local" drive is a new feature that we added around end of 2017. You just need to install the latest version DriveHQ WebDAV Cloud Drive Mapping Tool.  If you already installed an older version, you will need to remap your webdav drives to "local" drives. 

With a mapped "local" drive, you can use a very simple publish/search location. Instead of using the WebDAV URL, you can enter a regular file path like:

   Z:\FreeBusyInfo\JohnDoe.vfb   

(Assuming Z: is your mapped "local" drive, and the file exists at the specified path)
