Sync Object (Office)

The Sync property of the Document object in Microsoft Word, the Workbook object in Microsoft Excel, and the Presentation object in Microsoft PowerPoint returns a Sync object.


Beginning with Microsoft Office 2010, this object or member has been deprecated and should not be used.


Use the Sync object to manage the synchronization of the local and server copies of a shared document stored in a SharePoint site. The Status property returns important information about the current state of synchronization. Use the GetUpdate method to refresh the sync status. Use the LastSyncTime, ErrorType, and WorkspaceLastChangedBy properties to return additional information.

See the Status property for additional information on the differences and conflicts that can exist between the local and server copies of shared documents.

Use the PutUpdate method to save local changes to the server. Close and re-open the document to retrieve the latest version from the server when no local changes have been made. Use the ResolveConflict method to resolve differences between the local and the server copies, or the OpenVersion method to open a different version alongside the currently open local version of the document.

The GetUpdate, PutUpdate, and ResolveConflict methods of the Sync object do not return status codes because they complete their tasks asynchronously. The Sync object provides important status information through a single event, which the developer can access through the following application-specific events:

  • in Word, through the Sync event of the Document object or the DocumentSync event of the Application object;

  • in Excel, through the Sync event of the Workbook object or the WorkbookSync event of the Application object;

  • in Microsoft PowerPoint, through the PresentationSync event of the Application object.

The Sync event described above returns an msoSyncEventType value.

The Sync object model is available whether sharing and synchronization are enabled or disabled on the active document. The Sync property of the Document, Workbook, and Presentation objects does not return Nothing when the active document is not shared or synchronization is not enabled. Use the Status property to determine whether the document is shared and whether synchronization is enabled.

Not all document synchronization problems raise trappable run-time errors. After using the methods of the Sync object, it's a good idea to check the Status property; if the Status property is msoSyncStatusError, check the ErrorType property for additional information on the type of error that has occurred.

In many circumstances, the best way to resolve an error condition is to call the GetUpdate method. For example, if a call to PutUpdate results in an error condition, then a call to GetUpdate will reset the status to msoSyncStatusLocalChanges.


The following example demonstrates various methods of the Sync object based on the status of the active document.

Dim objSync As Office.Sync 
    Dim strStatus As String 
    Set objSync = ActiveDocument.Sync 
    If objSync.Status > msoSyncStatusNoSharedWorkspace Then 
        Select Case objSync.Status 
            Case msoSyncStatusConflict 
                objSync.ResolveConflict msoSyncConflictMerge 
                objSync.ResolveConflict msoSyncConflictClientWins 
                strStatus = "Conflict resolved by merging changes." 
            Case msoSyncStatusError 
                strStatus = "Last error type: " & objSync.ErrorType 
            Case msoSyncStatusLatest 
                strStatus = "Document copies already in sync." 
            Case msoSyncStatusLocalChanges 
                strStatus = "Local changes saved to server." 
            Case msoSyncStatusNewerAvailable 
                strStatus = "Local copy updated from server." 
            Case msoSyncStatusSuspended 
                strStatus = "Synchronization resumed." 
        End Select 
        strStatus = "Not a shared workspace document." 
    End If 
    MsgBox strStatus, vbInformation + vbOKOnly, "Sync Information" 
    Set objSync = Nothing
