Product(s) Affected:

  • BlackBerry Internet Service
  • BlackBerry Internet Service
  • Microsoft Outlook Web Access
  • Microsoft Exchange 2007, 2010 and 2013

The BlackBerry Internet Service is unable to connect to a Microsoft Outlook Web Access account which is using Microsoft Exchange 2007, 2010 or 2013.


The version of Microsoft Outlook Web Access that is included in Microsoft Exchange 2007, 2010 and 2013 uses a different communication method from earlier versions. The Microsoft Exchange Web Services component is required to be active on the Microsoft Exchange Server.


Verify that Microsoft Exchange Web Services is turned on and accessible on port 80 (HTTP) or port 443 (HTTPS) of the Microsoft Exchange Server. To check if Microsoft Exchange Web Services is turned on, visit one of the following Internet addresses:

Note: This test will only provide an accurate result when performed from a web browser that is outside the corporate firewall.

  • http://<maildomain>/EWS/Exchange.asmx
  • https://<maildomain>/EWS/Exchange.asmx

For example,

If Microsoft Exchange Web Services is turned on and functioning correctly, the web address should display an XML page after the correct credentials (username and password) have been entered.

Note: In Microsoft IIS, Basic Authentication must be enabled for the EWS Folder. By default this is disabled.
