Subscribing to ClickBook with Outlook 2003

Mark Demicoli  15 October 2010 12:35:46 PM

Microsoft Outlook 2003 does not directly support subscription to internet calendars such as ClickBook, however some very nice people have written a free tool for Windows which acts as an Outlook 2003 subscription service.

What this means is that Outlook 2003 users do not have to upgrade to Outlook 2007 or above if they are satisfied with what they have.

Just a small aside, Mozilla (the makers of the Firefox browser) now have a free competitor to Outlook called Sunbird.  It is not as feature packed as Outlook, but should be considered as an alternative for the money conscious.  You can try it out at the Mozilla website.

Important: These instructions are for Microsoft Outlook 2003 on Microsoft Windows only.

Step 1: Download and run the ICS40L installer from

Step 2: Copy your ClickBook subscription address

This is located in your Account tab if you are a Main Contact, or on the Preferences tab if you are a staff member.

Select the Non-password protected address, right-click and select Copy:

Step 3:  Load ICS40L from the Start menu

Step 4:  Paste your ClickBook subscription address into the first box, by right-clicking and selecting Paste.

At this point, you can click "Run Now" and see the new calendar appear in Outlook 2003, in the My Calendars panel:

It's probably a good idea to change the calendar name to something sensible, like "My ClickBook Appointments".

Step 5 (optional);  Set ICS40L to start automatically when you Windows starts up

a) Open the Control Panel and select Scheduled Tasks
b) Select Add New Task and click Next
c) Select ICS4OL from the Application list and click Next:

d) Select "When I log on" and click Next.

e) Finally, you may be asked for a user name and password.  This is the user name and password you use to log into Windows.
