Whenever I try to REPLY ALL to a large number of people, I am told that one of them cannot be reached. When I delete that one from the list, another one takes its place as unobtainable... and so on. What can I do to be able to send a single reply to the list of recipients that someone else has e-mailed without difficulty and of which I am one?
I don't know how to fix your problem but I do have a suggestion of how it might be remedied - add a fake email address as the last on the list of addresses, remember to start it with 'Z' as the mail/s might be attaching in alphabetical order, or create another email just to use to send to yourself and make sure it;s the last on the list. This is just an idea. I know a knowledgeable one will give you the right answer.
