Assuming you created the Calendar through the OWA at:
h tee tee p://<your server name FQDN>/Sharepoint Portal Server/Applications/
then...
Log onto the server, click Start-Run type CMD and press enter.
Next temporarily map to the M: drive by typing:
subst m: \\.\backofficestorage
This will map you to the Web Storage System. (Be sure it gets unmapped when you log off... I heard from someone smarter than me that it's bad to keep it mapped) Go to
Windows explorer then look at the M: drive. Here you will
see the applications folder. Drill to the Calendar (or message board, for that matter) you created. Right click to see the security settings... you will notice that the settings for everyone is read only. Change this to write. This will enable users to now post messages...and they can only delete out their own messages not others. If you give
them modify access they can delete out any and all messages. Then you can give the coordinator user id modify
access and he or she or it
![[rednose] [rednose] [rednose]](/data/assets/smilies/rednose.gif)
can delete out any message.
This works... no guarantee that it's kosher or politically correct.
