2. In the result pane, click Public Folder Management Console.
   
   
3. In the action pane, click Open Tool. The Public Folder Management Console appears.
   
   
4. In the public folder tree, click or expand Default Public Folders, and then select the parent public folder of the public folder that you want to configure.
   
   

   Note:
   To configure replication for the offline address book (OAB) or for Schedule+ free and busy information, expand System Public Folders, and then click OFFLINE ADDRESS BOOK or SCHEDULE+ FREE BUSY.

5. In the result pane, select the public folder for which you want to configure replication.
   
   
6. In the action pane, click Properties.
   
   
7. In <Public Folder> Properties, click the Replication tab.
   
   
8. To add a public folder database to the list of replicas, click Add.
   
   
9. In Select Public Folder Database, select the public folder database on which to replicate the public folder, and then click OK.
   
   
10. By default, Exchange uses the replication schedule set on the public folder database. To create a custom replication schedule for the public folder, clear the Use public folder database replication schedule check box and use the following settings in the corresponding list:
    
    
    • Never Run   The public folder is not replicated.
      
      
    • Always Run   The replication process is initiated during the replication interval set for the public folder database.
      
      
    • Run every hour   The replication process is initiated every hour.
      
      
    • Run every 2 hours   The replication process is initiated every 2 hours.
      
      
    • Run every 4 hours   The replication process is initiated every 4 hours.
      
      
    • Use Custom Schedule   The replication process uses the customized schedule that you create in Step 12.
      
      
11. To create a customized schedule, click Customize.
    
    

    Note:
    If you want to use a customized schedule, you must select Use Custom Schedule from the interval list.

12. To set the schedule, click the time grid in the Schedule dialog box. Public folder replication will run during the time slots that you specify. You can select the same time slot every day by clicking a column header for a specific time slot. You can select an entire day by clicking the name of that day.
    
    

    Note:
    The default time slot for the grid is one hour. For finer control, you can change the schedule grid to 15 minute intervals by clicking 15 minute. Scheduled intervals must be at least 15 minutes apart.

13. Click OK to close the Schedule dialog box.
    
    
14. To specify the age limit for items in this public folder, type the number of days in the Local replica age limit (days) box. Items that have reached the age limit are deleted.
    
    
15. Click OK to close <Public Folder> Properties and to save your changes.

This example sets the public folder My Public Folder so that it doesn't use the default replication schedule of the public folder database and replicates to PFDatabase02 on Server02 and PFDatabase03 on Server03.

	Copy Code
Set-PublicFolder "\My Public Folder" -UseDatabaseReplicationSchedule: $False -Replicas "Server02\PFDatabase02","Server03\PFDatabase03"

This example sets a public folder so that it always uses the default replication schedule of the public folder database.

	Copy Code
Set-PublicFolder "\My Public Folder" -ReplicationSchedule Always

This example sets a public folder so that it replicates only during the weekend.

	Copy Code
Set-PublicFolder \MyPublicFolder -ReplicationSchedule "Saturday.12:00 AM-Monday.12:00 AM"

Note:
The public folder replication schedule uses the format: "Weekday.Hour:Minute [AM/PM]-Weekday.Hour:Minute [AM/PM]"
