Scenario

There is a specific registry/policy setting that determines whether the Exchange Active Sync (EAS) account creation is allowed or disallowed in Outlook. In this article, you'll find out how to edit it.

Solution/Workaround

First, back up the registry (https://support.microsoft.com/en-us/help/322756/how-to-back-up-and-restore-the-registry-in-windows) to be able to restore it in case of any incorrect actions or unexpected results.

  • Close all Office applications.
  • Start Registry Editor (regedit.exe).
  • Locate and then select the following key:
    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Setup\
  • On the Edit menu, point to New, and then click DWORD Value.
  • Type EnableEASAccountCreation, and then press Enter.
  • In the Details pane, right-click EnableEASAccountCreation, and then click Modify.
  • In the Value data box, type 1 to enable, or 0 to disable EAS account creation, and then click OK.
  • Exit Registry Editor.

If you want to manage this by using policies (GPO), you can use this registry key as well:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Setup

Note: 16.0 in the corresponding key stands for Office 2016, 2019 or Office 365. If you're using a different version of Office, the key in the path will differ accordingly:

  • Outlook 2010: 14.0
  • Outlook 2013: 15.0
  • Outlook 2016: 16.0
  • Outlook 2019: 16.0
  • Office 365: 16.0
