I am having a time with this. It seemed easy but if you do a get email on multiple boxes in a flow you can use the send email at the end and it will mail the results of each and you can include subject, time etc....but....if there is not a email the flow will continue but never send a email at the end. If there happens to be a email in all boxes (which there usually is not) it will send the email. Its like the 1st get function step that does not see a email prevents knowing if any of the other mailboxes have one....kinda stuck on how to make this work.
My thought is to somehow insert a value indicating "No Email" or somehting like that so it will have a value and move to the next step without disrupting. Any thoughts would be much appreciated,
