He can see ours free/busy even from outlook 2007. we are in co-exsistence with 2003 and 2010. we tried to move his mailbox to different server but no luck. we tried Get-LogonStatistics but its not showing any result. but we can configure his outlook profile in my machine but issue still persist. I sent a test meeting and its showing in free/busy but old meetings are not showing. Any one pls help ? Regards Mager

Hello, Check the Autodiscover and Availability service by following the stops below on the Outlook 2007 client: a. While Outlook is running, click the CTRL key and then right-click the Outlook icon in the system tray and then select Test Email Autoconfiguration. b. Confirm that your email address is in the address field, uncheck Use Guessmart and secure Guessmart authentication boxes. Then click the Test button. c. Once it runs, please check the Log tab and Results tab. Thanks, Simon
