Exchange 2007 : You cannot open free/busy information

Exchange 2007 : You cannot open free/busy information

I had a user who was unable to add calendar entries to a Room Mailbox calendar. The error she received was:

You cannot open free/busy information. You do not have sufficient permissions to perform this opertation on this object.

This was caused by the user not having full mailbox permissions on the resource mailbox. Use the following command to configure mailbox permissions to allow the user to create new entries in the calendar:

Add-MailboxPermission -Identity “Room Mailbox 1” -User ‘domain\user’ -AccessRights ‘FullAccess’

You can also use the following command to apply this change to a number of similar named mailboxes, this command assumes that all the room names start with ‘Room’:

get-mailbox “Room*” | Add-MailboxPermission -User ‘domain\user‘ -AccessRights ‘FullAccess’

Windows 2003 : Print Server Printer ‘Offline’

Windows 2003 : Print Server Printer ‘Offline’

I ran into an issue recently where a printer kept going into an ‘offline’ state. This would occur randomly and would require the print spooler service to be restarted on the print server.

The solution was simple:

  • Under the properties of the printer select the Ports Tab 
  • Select the Port and click Configure Port
  • Uncheck “SNMP Status Enable”

The printer will now return to an online state and will work again.
