I'm not sure if this is the correct place to post this but here goes:
We have an application written in VB6 which automatically generates e-mails in Outlook . The customer in question was using use Outlook 2010 with Exchange 2003 they have recently migrated
to Exchange 2013. Since migrating all generated e-mails have stopped being sent out and are all being bounced back with:
Remote Server returned '550 5.1.0 RESOLVER.ADR.InvalidInSmtp; encapsulated INVALID address inside an SMTP address (IMCEAINVALID-)'
When I go into Outlook to try to resolve the issue and drive down into the properties of the recipient of the e-mail the e-mail type field is blank (see screen shot below) where as before the migration the e-mail type always defaulted to SMTP. I'm not sure if this is what is causing the issue but its the only difference i can see post migration.
I have looked at the Outlook object model and cannot see where I can set the E-Mail Type property. Can anybody advise my how i can programatically set the E-Mail Type property to SMTP
Thanks in advance
