PRB: When sending from Zetadocs PDF using Outlook, error 'Could not retrieve IMessage: Interface not supported' occurs Print ZTN3557 ID: ZTN3557 This Zetadocs PDF technical note applies to: Zetadocs V4 Microsoft Outlook Symptom The following error dialog occurs as Outlook starts, after pressing the send button from Zetadocs PDF: Cause This error occurs when Outlook and Exchange Server 2003 are installed on the same machine. This is not a supported configuration from Microsoft. Installing both Outlook and Exchange Server 2003 on the same machine will create conflicts with differing versions of critical dll files used by both applications, leading to unpredictable behaviour. Resolution Install Exchange Server 2003 and Outlook on separate machines. Status This has been identified by Equisys as a problem with the software versions given above.
