Hello All,

After a long migration at my last client there is a few issues around Outlook 2003 clients and the free/busy.

* This issue occurs only on Outlook 2003, Outlook 2007-13 everything works fine.

To fix this issue :

First Option – Upgrade the Outlook 2003 to 2013

Second – Do a workaround

Fist try to run this command on the Outlook 2003 client : outlook /cleanfreebusy

If u receive an error “Unable to clean your freebusy information”

You can update the Outlook 2003 user profile with RPC encryption for a test.

1. In Control Panel, open the Mail item.

2. Click Show Profiles.

3. Select your profile, and then click Properties.

4. Click E-mail Accounts.

5. Select View or change existing e-mail accounts, and then click Next.

6. Select the Microsoft Exchange Server account, and then click Change.

7. In the dialog box that contains your mailbox server and user name, click More Settings.

8. In the Microsoft Exchange Server dialog box, click the Security tab.

9. Click to select the Encrypt data between Microsoft Office Outlook and Microsoft Exchange Server check box, and then click OK.

10. Click Next, and then click Finish.

11. Click Close, and then click OK.

If u still cannot see the Free/Busy :

To resolve this problem, follow these steps

  1. In the Exchange Management Shell, run the following command:
    get-publicfolder -Identity “\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY” -Recurse | fl name,Replicas

    Notice that at least one of the SCHEDUE+ FREE BUSY folders is missing an Exchange 2010 or Exchange 2007 server listed as a replica. For example, the output may appear as follows:

    Name : EX:/o=contoso/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)  Replicas : {}
  2. In the Exchange Management Shell, run the following command:
    set-publicfolder -Identity “\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\” -replicas “”

    For example, type:

    Set-publicfolder –identity  “\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=contoso/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)” –Replicas “Server\Storage Group\Public Folder Database”
  3. Verify that the public folder group now has a replica using the command from step 1. In the following example, the folder now has a replica object.
    Name : EX:/o=contoso/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)  Replicas : {Public Folder Database}

Hope this was Informative,

Henry Hazot
