I updated my live.com email account to outlook.com email today and am in the process of updating my email and calendars from Gmail. I tried to share my main calendar with my wife, still on Gmail, but am getting the following error:

There's a problem sending your invitation because you've hit the limit for the number of messages you can send in a day. You can increase this limit by verifying your account in Hotmail. Just go to your inbox and send a message from there. Then come back to Calendar to send this invitation. Sorry for the inconvenience. (redacted)@gmail.com

I've gone back into outlook.com and sent her an email saying that I am trying to share my calendar with her but I keep getting this same message. I've deleted my cache and temp internet files. I am on Win7 Home Premium using IE9 and Windows Live Mail. I am attempting to share through IE, not Live Mail.

Why am I limited in the number of messages I can send in a day? I had previously tested the calendar by inviting her to a test event. She hasn't responded to that yet so I don't know if she got the invite.

Thanks,

Brian
