Applies to Exchange 2010 Outlook 2010
Problem:
User can successfully set OOF. Also other users can see that she is OOF in mail tips in outlook. But OOF rules does not work.
Cause:
PR_OOF_STATE Property Name of the mailbox is always true even if you disable OOF.
You can see PR_OOF_STATE Property Name value of the mailbox by using MFCMAPI.

Solution:
1- Disable OOF using Outlook. PR_OOF_STATE is still true
2- Enable OOF using OWA page. Outlook still shows OOF is disabled.
3- Disable OOF using OWA page. Now PR_OOF_STATE is false
4- Enable OOF using OWA page . Outlook shows OOF is enabled
5- Send message to the user and now sender recieves the OOF message
