Many of our clients use a combination of communication tools to keep in touch — whether Outlook/Exchange, Apple Mail.app, Entourage, or Google Apps. Combining these tools can create some technical challenges, as technologies from different manufacturers don’t always play nicely together. Today I wanted to share a workaround that I use in my personal calendaring setup: using Google Calendars with Apple’s iCal. This necessitates figuring out how to get Google Calendar ‘delegate calendars’ to sync with iPhone/iPod Touch via iTunes.
Google Calendar is a great tool for managing appointments, accessible from anywhere (check out Colin’s thoughts on Google Apps). It is also very versatile as it offers the ability to import iCal .ics files and MS Outlook CSV calendar snapshots. A delegate calendar is an additional calendar you can add to your existing Google Calendar account. At the present time, it is not possible to sync/view delegate calendars when syncing an iPhone/iPod Touch from iTunes. They will not show up there as it looks like this feature is not supported/implemented at the present time. There is a simple workaround which will allow users to sync delegate calendars from within iTunes. The following steps will guide you through the process:
STEP 1: disable your delegate calendars from iCal
- Open iCal, then select ‘Preferences’ from the iCal dropdown menu
- Select your Google CalDAV account and open the ‘Delegation’ tab at the top of the window
- Uncheck each checkbox corresponding to each delegate calendar; they will disappear from the main calendar view where they were currently shown as delegates
STEP 2: create the necessary account(s) for each delegate calendar
A typical Google Account URL has the following form: https://www.google.com/calendar/dav/USERNAME@gmail.com/user
This should be already present on your existing CalDAV account (the one you expunged the delegates from). Replace ‘USERNAME’ with your Google Account username, then copy and paste the line above into a temporary text document for now.
- Open your browser and log in into your Google Account, then follow the Calendar link
- Select ‘Settings’ on the ‘My calendars’ box on the left column of the page
- Select the delegate calendar you want to keep in sync from the main page’s frame
- At the bottom of the next page (the with the selected calendar’s details), copy the Calendar ID value (shown as clear text) which can be found in the ‘Calendar Address’ section; the Calendar ID has the following sample structure: email@example.com
- Go back to the previous temporary text document where you saved your Google Account URL, paste the Calendar ID value you copied in the previous step and replace the ‘USERNAME@gmail.com’ part as follows (replace the Calendar ID with your correct value):https://firstname.lastname@example.org/user
- Then copy the whole resulting string
- Go to iCal, select Preferences once again and add a new CalDAV account: please make sure you expand the ‘Server Option’ dropdown and paste the aforementioned string into the ‘Account URL’ field.
You will need to create a brand new iCal account for each delegate you have set up on Google Calendar. When done, your iCal software will display each delegate(s) as separate calendars, and each one of them will be shown into iTunes and will be available for synchronization in the Device’s Info tab.
