I have been having trouble with this for the last three days in the native email module. All of my scenarios that had been successfully running with the native email module also started timing out at the same time. Support has offered no solutions for my issue but suggested I switch to the dedicated Gmail module. I’m testing that now. Not sure if my situation is relevant for you or not.
I switched to the outlook module, it worked
It seems that the performance issues and timeouts that I’ve experienced over the last three days are resolved for now. My old scenarios with the generic email module and my new scenarios with the gmail module both are working for now.
