Settings.saveAsync method

Persists the in-memory copy of the settings property bag in the document.

Hosts: Access, Excel, PowerPoint, Word
Available in Requirement set Settings
Last changed in 1.1


    Type: object

    A function that is invoked when the callback returns, whose only parameter is of type AsyncResult. Optional.

Callback Value

When the function you passed to the callback parameter executes, it receives an AsyncResult object that you can access from the callback function's only parameter.

In the callback function passed to the saveAsync method, you can use the properties of the AsyncResult object to return the following information.

Property Use to...
AsyncResult.value Always returns undefined because there is no object or data to retrieve.
AsyncResult.status Determine the success or failure of the operation.
AsyncResult.error Access an Error object that provides error information if the operation failed.
AsyncResult.asyncContext Access your user-defined object or value, if you passed one as the asyncContext parameter.


Any settings previously saved by an add-in are loaded when it is initialized, so during the lifetime of the session you can just use the set and get methods to work with the in-memory copy of the settings property bag. When you want to persist the settings so that they are available the next time the add-in is used, use the saveAsync method.

Note: The saveAsync method persists the in-memory settings property bag into the document file; however, the changes to the document file itself are saved only when the user (or AutoRecover setting) saves the document to the file system.

The refreshAsync method is only useful in coauthoring scenarios (which are only supported in Word) when other instances of the same add-in might change the settings and those changes should be made available to all instances.


function persistSettings() {
    Office.context.document.settings.saveAsync(function (asyncResult) {
        write('Settings saved with status: ' + asyncResult.status);
// Function that writes to a div with id='message' on the page.
function write(message){
    document.getElementById('message').innerText += message;
