A user of OWA (outlook web access) cannot create an event on a public shared calendar and invite attendees, the invite \button is grayed out. This is by Microsoft design (google it). In order to allow an OWA user to create a calendar event with his calendar, other users calendar, and a public calendar, \the public calendar must be assigned an email address and the OWA user must create the event from his own personal \calendar, then click invite, then search for the public calendar as an attendee. When he saves the event, it will \be saved on his personal calendar, the public calendar, and any other user attendees he has selected.For dynatron, I setup a 'Conference Calender' and a 'Impl & Trng Calendar' public calendars. Note, to get email \working as a resource for these calendars you do NOT have to create an Active Directory user and an exchange mailbox. \These public calendar emails will not even use an exchange mailbox, just the address. So no AD editing needed. \Just open the exchange System Manager on your exchange server. Expand 'Administrative Groups'->'first administrative group'-> \'Folders'->'Public Folders'. Properties on your public calendar folder name. E-mail Address tab. Add theemail@domain.com \SMTP. Goto Exchange Advanced tab, uncheck the 'Hide from Exchange address lists' box (this way it shows up in your \outlooks Global Address List). And thats it.If you wanted a calendar as a true resource, to deny duplicate bookings etc... you cannot do it with a public \calendar. In order to do this, the calendar has to be owned by a regular AD user with a regular exchange mailbox. \See http://www.slipstick.com/calendar/skedresource.asp So you would setup an AD user, then login to outlook as that \user, goto Tools->Options->Preferences Tab->Calendar Options->Resource Scheduling and check the first 2 or whatever \checkboxes. Then delegate users to manage this calendar and allow others to view/edit etc...Doing this user calendar instead of a public calendar will also allow others booking an event to see the calendars \free/busy information (cannot see free/busy info of a public calendar http://support.microsoft.com/kb/260724)

calendar/mail/contact...Just open outlook as admin, or one who has admin access, and right click public folder, create, then select the correct \'Folder Contains'. Then if you want it as a resource like above, goto exchange System Manager and goto properties on \the new public folder item...
