In response to an old topic we have here.

I am currently experiencing a problem, so far only isolated to two
Blackberry users, who are getting duplicate attendees appearing only
from users at our second site. Both sites are running Exchange 2003 SP2
and we have one Blackberry server at site A running BES 4.0.4.9.

For example, Geoff from site A invites Jill from site A and Bill from
site B. On response from both users Jill from site A will appear once
and Bill will appear twice, three times sometimes four.

I have spoken with Blackberry who have advised that this problem was
fixed with our current version of BES. I have made sure the cdo.dll
diles are the same on both servers to ensure consistency but this has
not rectified the problem.

Any ideas?
