Meeting "Not Current"

What is the OL Client of the meeting owner / updater / receiver ?

Owner and receiver both are on Outlook 2007.

Here is the scenario:
we have 2 execs with 2 diff. admin assistants.
Admin 1 manages and sends meeting invites to everyone and same is for Admin 2.
Admin 1 sends out an update for a recurring meeting for which Admin 2 and Exec 2 are invited and both gets such messages (attached screenshot).
Admin 1& 2 are on outlook 2007 SP2 , same time zone.
Exec 2 is on outlook 2010 and has a Blackberry. However he is not configured to receive any meeting invites or updates as all are being forwarded to Admin2.

Hope this explains the situation better.

I do not have an OL2k10 but if I were you I would try to reproduce this scenario keeping Exec2 having Ol2k10.

All i can state is - are all these users having same time frame / zone? Apart from that a simple repro should rule out a problem with Ol2k10 being involved.
