SUMMARY

When the OWA web site is configured with Require Client Certificates under Secure Communications in IIS, users receive the following error when viewing attachments:

Invalid conversion id 64-0x0”

CAUSE

Requiring client certificates for accessing OWA is not currently supported with Messageware AttachView, as file conversions cannot be retrieved from the server using a client certificate.

RESOLUTION

To work around this behavior, disable the Require Client Certificates setting in IIS by following the steps below

1.     Open the IIS Manager

2.     Right click the OWA Web site, and select Properties

3.     Navigate to the Directory Security tab

4.     Click Edit under the Secure Communications section

5.     Uncheck Require client certificates

6.     Click OK, then Apply and OK
