This feature allows the BlackBerry Messaging Agent to automatically discover whether to use Messaging Application Programming Interface-Collaboration Data Object (MAPI-CDO) or Microsoft® Exchange Web Services. The functionality can be overridden by using a trait.

The BlackBerry Messaging Agent attempts to use Microsoft Exchange Web Services for calendar functionality when possible, without additional configuration out of the box.

  • The existing BlackBerry Administration Service trait “EWSEnable” semantics remain if an administrator prefers to explicitly force the usage of MAPI-CDO or Microsoft Exchange Web Services

The use of Microsoft Exchange Web Services or CDO is determined for each user.

Mailbox moves from Microsoft Exchange 2000 or 2003 to Microsoft Exchange 2007SP1 to 2010 and later enabling of Microsoft Exchange Web Services do not require a restart of the BlackBerry Messaging Agent.

Failure to use Microsoft Exchange Web Services due to Microsoft Exchange or Windows® configuration errors results in a fallback to CDO (the default being Microsoft Exchange Web Services) with logging indicating cause of Microsoft Exchange Web Services failure.

Other related changes

CalHelper self-tests are modified to test Microsoft Exchange Web Services and MAPI-CDO versions where both are utilized by a BlackBerry Messaging Agent.

  • The Microsoft Exchange Web Services and MAPI-CDO CalHelper self-test is run with a matching Microsoft Exchange Web Services and MAPI-CDO enabled user

User Availability (Free or Busy lookups) are obtained via Microsoft Exchange Web Services or MAPI-CDO public folders as determined by the requestor's use of Microsoft Exchange Web Services or MAPI-CDO.

  • The current fallback strategy to or from MAPI public folder and Microsoft Exchange Web Services remains
