Dear Support,

email was sent using " members-632593@toastmastersclubs.org" in Microsoft Outlook.. Apparently none of the club members have recieved the email. I have not got any error or Warning message either Club website admin ( me) .

This has created a big hassleto the Excom to mail out agenda's or for Fee collections reminders.

What might be the solution to this.

I have got thebelow email error ..............................................
