Emre,
Thank you, works with my mail server now.
But wait - there's more.....
If you have DeleteFile selected, it doesn't.
If the file doesn't exist you get an error when trying to send an email.
PS - I worked out that the files are XPS files, so that's all good now.
So here is my problem. I want to email 4 reports when a Work Period Ends. But because the Rule completes faster than the files get created, I get errors sending the emails.
To get around this, I have it set to create the reports at end of Work Period, then email the files when the User logs off.
Can we combine the File Creation & Email Actions into a third Action? I assume you can only send 1 file per email?
