I have a strange issue that I'm unable to find the answer to online or by looking at it myself.
Basically when I set up an email subscription for a report I've created in SSRS Report Builder (2008); I can render my report into any format other than PDF and it will be sent to me successfully. The report is a table that returns some client information from our recruiting database; nothing complicated and it does work correctly if I choose another format.
If I try and send as a PDF I receive the error: 'Failure sending mail: The transport lost its connection to the server.'
I can export the report into PDF format if I run it from the report designer and the file size for the fully rendered PDF is ~35kb so I can't imagine a timeout.
It is baffling me and I'd like to know the root cause.
Thanks for your time.
