@fred.too

Can you share the properties of Send SMTP Activity

If you are using Variables, can you hardcode the values and try again

Also, try with updating / degrading the mail packages

Hope this may help you

Thanks

Hi,

I can’t share the properties as SMTP information/credentials are confidential.

Values are being parsed as argument. Used hardcoded value, still the same issue.

Used same package but different SMTP server, worked like a charm, so I don’t think is the package issue.

I just want to know why powershell works, but this activity does not. Executes both test from the same machine.

Thanks for your suggestion.
