title: Max length of iCalUId
body: <p>when creating events in outlook calendar you get a few ids to help "track" the event, I have a database and want to store <code>iCalUId</code> like so: <code>KalenderEventId nvarchar(max) null</code> but I can't find the max length of that object. What is the length of <code>iCalUId</code>? </p>
