Hi Zilvinas,
I tested in 8.5 2020-03-24 B 241.
I create the email in the users email box, and select 'Sent'. If I check the Email queue register the status is 0 - Queued (and remains on this state).
If I go to Routines>>Maintenance>>Send and Receive email>>Run, the email is then sent out and status changes to 1.
Do I need to change any settings so that it sends the email the first time when I select Sent and Save?
