One user can not see free busy in Outlook 2010

I have recently installed an exchange 2010 server and I have one user who cannot see anything from anyones free/busy as shown in the photo below.  He is using Outlook 2010 as well.

Try following:
1. If one user is unable to see free busy information of other users from Outlook, check if he can see from OWA. If he can see from OWA and not from Outlook, then the issue is with his Outlook client. This is not server related issue. Create a new Outlook profile for the user or configure his Outlook profile on a different machine. Also try sending a new meeting request by configuring the user's profile in online mode. Make sure Outlook is not set to work offline.

2.  Run Outlook with "/cleanfreebusy" Switch. This switch resets the Resource Scheduling and Delegate Settings. Once Outlook has started with this switch, it will clear and regenerate free/busy information, removing scheduled resources from mailboxes that no longer exist. In short, it will update the free/busy information.

1. From your computer's Desktop screen, navigate to Start and select Run

2. At the Run dialog box type in: Outlook.exe /cleanfreebusy

PLEASE NOTE: you must include the space between Outlook.exe and the /cleanfreebusy switch

3. Press OK

Even the affected user can check the above three steps.


You can ask the user to follow the below steps and ask the below questions:

1. Configure a new profile in Outlook online mode and check the free busy information.

2. Start Outlook with Outlook.exe /cleanfreebusy from run command.

3. Check in Tools--->Options and Delegates tab. See if there is any other user as delegate and check what all can the Delegate does on behalf of the owner.


A. How often does the client experience this problem? Is client able to view/publish free/busy sometimes?

B. If one user is unable to view another user's free/busy, can anyone else that person's free/busy information?

I have the same issue in Office 2010. I cannot see free/busy in my calendar.  I also lose organizer rights so when I delete the invite, the reminder does not remove for the attendee's calendars.  I checked OWA and I cannot see the scheduling assistant tab for any calendar entries I have where others have been invited to attend.  I tried the solution above Outlook.exe /cleanfreebusy.  This did not fix the issue.  I checked and there are no other delegates in my Outlook.  There is another user that also just have Office 2010 installed that is having the same issue.
Thank you vinaykrai for your guided resolution path. I have been troubleshooting this very issue with a lone user. I have tried everything, just short of a new profile, which was the next step. Your post confirms my hunch.

User does, in fact have calendar ease via OWA. That is when it cemented it for me, that the Outlook client was the culprit.

Thank you again. So often "fix it" steps are not as clear and simple as yours. Very nice.
