I have a small business where my partner and I share an email address in order to both be "in the loop" on any coresspondence. We both have our own computers where we check that mail, as well as smart phones where we also both check that email. The problem is, if one of us reads/opens an email, it is marked as read for the other computer and/or smart phones. I'm looking for a way to make our email NOT be marked as read except on the actual device it was read/opend from. So if I check email on my phone, I'd like that particular message to still be considered "unread" on my computer and partner's computer and phone. Is there anyway to have such a set up? Currently we are missing important emails because they show as read and are looked over. Any help would be greatly appreciated.
