We just migrated from SBS and Exchange 2003 to Standard 2008 and Exchange 2010, and we have Filemaker 11 Advanced Server. The migration seemed to go fine, but our SMTP email script steps in Filemaker will not go through if 1) an outside email address exists or 2) if a duplicate email address exists. And, the email script step DOES work if it is send to internal email addresses ony with no duplicates in them. Also, you CAN send to an external email or send if a duplicate email exists from the Admin console (see 1st screen print) (See 2nd screenprint for SMTP script step settings set from one's workstation.).
Other than the new exchange server address, the only other change has been that we were set up with an open relay and so no longer use the Plain authentication method. Any suggestions. We've run out of options. Is this an Exchange or a Filemaker issue.
