 Designing an add-in for mobile introduces some additional considerations.
 
-### Use REST instead of Exchange Web Services
+### Use Microsoft Graph
 
-The [Office.context.mailbox.makeEwsRequestAsync](/javascript/api/requirement-sets/outlook/preview-requirement-set/office.context.mailbox#methods) method isn't supported in Outlook mobile. Add-ins should prefer to get information from the Office.js API when possible. If add-ins require information not exposed by the Office.js API, then they should use the [Outlook REST APIs](use-rest-api.md) to access the user's mailbox.
-
-Mailbox requirement set 1.5 introduced a new version of [Office.context.mailbox.getCallbackTokenAsync](/javascript/api/requirement-sets/outlook/preview-requirement-set/office.context.mailbox#methods) that can request an access token compatible with the REST APIs, and a new [Office.context.mailbox.restUrl](/javascript/api/requirement-sets/outlook/preview-requirement-set/office.context.mailbox#properties) property that can be used to find the REST API endpoint for the user.
+Add-ins should prefer to get information from the Office.js API when possible. If your add-in requires information not exposed by the Office.js API, use [Microsoft Graph](/graph/overview) to access the user's mailbox.
