Free/Busy sometimes not showing more than 2 months ahead


I'm hoping someone can help me with a problem we're experiencing with Free/Busy.
We have our Outlook clients set (through a group policy) to publish 24 months of free/busy data.
However, sometimes the free/busy data is reset to the default 3 months.
When this happens, it often requires "outlook /cleanfreebusy" to get it to 24 months again, though sometimes it's enough if the user logs on to their mailbox with Outlook.

Since this happens mostly with Blackberry and/or PDA users, we expect CDO may be the problem.
I found articles stating that CDO defaults to 3 months, but can be programmatically set to publish more. I do not see any options for this in our Blackberry Enterprise Server.

Any idea how I can assure that all my applications (and especially the BES) publish the same amount of free/busy?

Is it also possible that OWA messes things up? I know that OWA uses a different method to publish the data, but I'm not sure if it could cause this problem.

Any thoughts are appreciated.

What is the version of store.exe on your box? is your blackberry updated with all updates available?
what is the version of cdo.dll on Exchange and Blackberry?

OWA should not be doing anything in this case. Its most probably the Blackberry, which is resetting it back.

Do you have this registry key in place?

This is the number of months of FB data you'd like to publish.

if not, add this key on the Exchange server. stop and restart IIS Admin and System Attendant.
re-publish Free/Busy using outlook. (outlook.exe /cleanfreebusy) and then republish it ( send a test meeting request and make someone to accept that).
login through OWA and check the blackberry also.

see, if it works.

Unfortunately, not all problems are fixed, but I think the change fixed most of them, so Thanks!

The problem that's left differs from the rest. One user's free/busy disappears completely. After /cleanfreebusy the information is visible, but after a while, no free/busy (not even 3 months) is visible... Any ideas? Or should I post a new question?
