Email Tool - fails if I try to send to 34

[bstephenf2]

I have a workflow with an Email Tool at the end. It has been working fine but then I was asked to add some people to the distribution and it failed with an error:

"Unable to send email $P"

To test the limit, I started removing some of the added recipients and found that I could send to 33 emails but upon adding the 34th email address it fails again.

• the 33 emails have a string length of 982
• adding 1 more email (which fails) has a string length of 1008

Is there a known limit to number of emails I can send to or a limit to the string length for the TO or CC fields?

I resolved by running from the Alteryx Server via the scheduler and it worked without making any other changes to the workflow, so it was something to do with my local PC. It would be nice to have a solution for running locally but at least I have a workaround.
