How do I invite to a calender event

How do I send or invite someone a calender event if they are not a contact. I use Salesforce.com manager my contacts and I just need to send the calender event to a client.

Hello,

when you are creating new event - right click - scheduling tab - add.

then in field “user:” put email of person/s you want to invite and click on okay. Does this work for you?
