How can I resend invitations to a shared Google calendar?
I've setup a new calendar for a non-profit organization using Google Apps for Domains. I said "no" to the initial question to send out invites because I wasn't finished tweaking it and didn't want the notice to go out until it was ready.
Now that I've finished setting up the calendar (I added a year's worth of funding deadlines, meeting dates and other important dates) I want to send out the invitations, but I haven't been able to figure out how.
The calendar is not public.
Note: This is about invites to the calendar itself, not to shared events within a calendar.
Best Answer
To share an event
You should be able to change this when you click to edit the event.
(I'm looking @ this now as I'm telling you)
Click the event you want to get to the edit page. To the right middle of the screen you can add guests and give those guest privileges. After you've enter the email(s) of the guest(s) you want to add, click add. Down at the bottom of the page is privacy settings. If you need to make the event public naturally you should know what to do.
If you click the link "Publish this event" it'll create a link you can share with others.
To share the entire calendar
If you are trying to share the entire calendar, on the main calendar page click the arrow next to the calendar and select "Share this Calendar". Follow the instructions and you should be good to go.
This link leads you to a search (through google calendar help) of sharing topics. If it doesn't help you can always search again in the search box.

Another thought
Have you tried sharing the calendar ID? It's in the specific calendar's settings. It's another way to share the calendar.
(This is in comments but I'll add it here to make it easier for everyone else.)
I've found this. Not sure if you've been through it and I'm not quite entirely sure how to answer the questions so I'll pass it off to you. http://support.google.com/calendar/bin/answer.py?hl=en&answer=144119 . And I found this http://support.google.com/calendar/bin/answer.py?hl=en&answer=143754. If you read the section about sharing with specific people outside your domain, it gives what you can't give them permission to do. Like see private events.
You're going to need those "outside" people signed up for account inside your domain for this to work. It's the only way.
