When attempting to schedule a CA Business Intelligence (CABI) report to be emailed to an user, error received:

[CrystalEnterprise.Smtp]: [Error sending address(es) to SMTP server. Return code: [SMTP 550 - Requested action not taken: mailbox unavailable.].

Environment:
CA Business Intelligence (CABI) 3.xWindows OSCA Service Desk Manager (CA SDM) 12.5, 12.6, 12.7 and 12.9Microsoft Exchange Email Server
Resolution:

SMTP 550 is purely a SMTP-server error. The email address to which report has been scheduled is not recognized by the SMTP server/domain server.

SAP has reported that similar issues have been resolved by adding the CABI Central Managament Server (CMS) IP Address in the Microsoft Exchange Relay Restrictions:

  1. Login into Exchange Server System Manager
  2. Click on Server
  3. Go to Protocols>SMTP
  4. Go to Virtual Server Tab>Access> Relay Restrictions
  5. Click Add and a dialog box with available IP addresses appears.
  6. CMS Server IP Address to allow list and Click OK
