PRB: Cannot send faxes from Outlook after migrating to Exchange 2010

Print

ZTN1800

ID: ZTN1800

This Zetafax technical note applies to:

  • Zetafax 2010

Symptom

After sending a fax from Outlook using the Exchange connector, the message is immediately rejected by the Zetafax Server with the message “User not registered”.  The user’s mailbox has been recently migrated to Exchange 2010 from Exchange 2007 but the Zetafax connector has not yet been migrated.

Cause

The TNEF encoding used in the email message is not compatible with the Exchange 2007 connector.

Resolution

Migrate the Zetafax connector to an Exchange 2010 hub transport server.

  1. Remove the existing connector from Exchange 2007 using Add/Remove Programs.  If it was originally installed using the manual method, follow this technical note - http://www.equisys.com/technotes/ztn1616.htm.

  2. Install the new connector for Exchange 2010 - http://www.equisys.com/support/software_downloads.html.

Status

This has been identified by Equisys as a problem with the software versions given above.
