Outlook 2010 beta - 4 problems - NEED HELP

Hi ,
New software - old problems

1. Clear the messages from the server (not leave them on the server)
2. On a new account creation , take messages from a specific date and further(not all the messages that were prevously opened and now are lying on the server)
3. Unopened items directory is missing
4. Integration with AV software (i.e NIS or KIS) - they don't recognize the mailbox and their addons are not visible in it (wild guess maybe because oultook is x64 and they are x32 ?)

THNX A BUNCH GUYS

1. To change the behavior of the messages to server,
Select File
Account Settings
Double click on your account from the list
Select More settings on the right
Select Advanced
At the bottom, change how you want messages to be handled.

2. Don't know if this can be done.
3. Never saw this directory. If you are speaking about the "evelope icon" in the system tray, it is not included in the beta but is in the final Outlook 2010.

4. If it is x64 Office, then connections to x86 (32bit) functions do not work as you suspect.

THNX MAN , someone else knows ?

I remember that on office 2003 there was such directory (unopened items).
Another thing, how do I set the messages's HTML text to be viewed as context-dependent ? (e.g english text left-to-right , hebrew text right-to-left)

REALLY APPRECIATED
