Meeting Invite/Update Problems

<< sorry for cross posting - also in the curve forum - I posted in wrong place on first try >>
I'm having a couple of very annoying problems about scheduling meetings.

Context: I have a Curve 8330 on Sprint and use BIS

Problem 1: Duplicate meetings in my calendar
1. Let's say I setup a meeting from on my BB and invite an attendee
2. Looking at my calendar, I see the meeting there (once).
3. Later on (after I get both my auto cc back for all sent messages, and the other person accepts the meeting), I now have the meeting in my calendar twice.

Note: I have not sync'd in the interim - this is all on the BB handheld.


Problem 2: Can't receive meeting updates or cancellations
While the BB can understand new meeting invitations, I can't get it to recognize meeting updates and meeting cancellations from others using outlook (standalone or with Exchange).

In replies, please consider that I use BIS

Thanks a lot,

Steve
(very frustrated)

Ever get a solution to this? I have the same issue. :(

I to have the EXACT same problem. Any solution would be nice!
