is it possible to share my Office 365 calendar with an external user WITH write permissions ?

We have our own domain and it is hosted on a Office 365 subscription. I know you can switch on calendar sharing for external users. They will receive a link with which they can consult you calendar and see busy/free times. But they cannot write in it.  I'm looking for a solution so that a non domain-member can read & write into my Office 365 Online calendar. Is this possible ?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

To put it simply, no. No built-in methods for that, but you can do some web-based tool that writes to the Calendar via EWS or similar, put some access controls on it and so on.
