title: Maximum number of devices allowed to use the same Outlook account
body: <p>What's the <strong>maximum number of devices that can use an Outlook account at the same time</strong>?
  I need to keep an Office365 user logged in (for months) on 7 tablets at the same time plus sporadically access it from a browser.</p>
  
  <p><strong>Context</strong>:
  I'm developing and Android application, based on <a href="https://dev.outlook.com/restapi/tutorial/android" rel="nofollow">outlook-sdk-android</a>, that talks with the <a href="https://msdn.microsoft.com/en-us/office/office365/api/calendar-rest-operations" rel="nofollow">Outlook Calendar REST Api</a>. The app uses an <a href="https://github.com/OfficeDev/Outlook-SDK-Android/blob/master/sdk/outlook-services/src/main/java/com/microsoft/services/outlook/fetchers/OutlookClient.java" rel="nofollow">Office REST Client for Android</a> (a shared client stack provided by <a href="https://github.com/msopentech/orc-for-android" rel="nofollow">orc-for-android</a>) .</p>
  
  <p>Thanks</p>
