Ok, I think I see. I'm subscribed to the thread, but it won't send me an email saying that there's been a reply unless I have the "Everything in my Inbox page" setting change to Yes, correct? If so, is there some reason those emails aren't part of the "Direct social actions" setting?
FYI, I checked our spam filtering appliance and there are no messages that have the words solarwinds or thwack in the subject or from fields that were for me. I don't do spam filtering on my Inbox at the Exchange or Outlook level. Also, I receive my weekly summaries.
Thanks for the assistance,
