I currently have iCal syncing to one Google account with 1 main calendar and 3 sub-calendars (selected on Delegation tab). Let's say that this account is [email protected].

This is the only one account set up in iCal.

Additionally I have 4 email accounts defined in Mail.app in this order:

  1. [email protected]
  2. [email protected]
  3. [email protected]
  4. [email protected]

Problem 1 - iCal will not send out invites to attendees

I cannot make iCal send invites when creating an event within a calendar that's synced with Google.

I have to create a local calendar on Mac, create an event there - invites are sent out "correctly" (see Problem 2), then I simply move the event from one calendar to another and this seems to do the trick.

This seems to be a bit troublesome though (obviously, really). Is there anything I can do to make it work properly - so the invites are sent out from Google's CalDAV calendar?

Problem 2 - iCal invites email addresses

iCal seems to be totally inconsistent with using email addresses when sending invitations.

Consider the setup:

  • 1 CalDAV account in iCal ([email protected]),
  • 1 local calendar (as mentioned in Problem 1),
  • 4 email accounts in Mail (as described above).

Now iCal seems to be sending invites using the topmost email account set up in Mail.app - in this case [email protected]. Is there a way to use different email account to do this?

Also, it seems that iCal creates invites using the email account defined in iCal accounts - in this case [email protected], even though I use local Calendar and not the CalDAV one!

This means that invite is sent from [email protected], but people replying to invites send them back to [email protected]. This really is plain wrong. Any way to sort it out?

NOTE: Ideally I'd like iCal to send invites from the second Mail account - [email protected].

iCal doesn't send invitations - Google Calendar do.

You need to set up Notifications for each Google Calendar - main and sub-calendars.

"Google Cal->Calendar settings->Calendars->[select calendar]->Notifications->[set check mark at Email and/or SMS for each type of invitations]"

Someone needs to read the help files on google's page... Just because you've sync'd your google cal w/ ical doesn't mean you can go & send invites to anyone willy nilly. Have you told google that your going to "share" your cal w/ this other person who may or may not have a google account? Did they accept your ical share? As far as "sending out" invites, that'll happen off your "default" email account. Generally iCal will send out a "link" to your event & lots of people just click on that to go to a page where they "accept" or "deny" or "reply" to your invite, so auto received from your gmail account. You could set up a rule to forward them to your other email account if you prefer?
