This is a less than an ideal way to handle this, IMO. That is a LOT of stuff getting pulled down and it would not be friendly to those on slow connections (like I am) and on lower performance hardware. I am not sure that I have a good suggestion on how to solve this issue, as I don't know a heck of a lot about how all that stuff works. I would think that one could use a tag of some sort to designate an event "outside" the encrypted data so that you only pull down the messages that are tagged with the calendar data tag.
