Hi I have a certain group of email addresses on my company which requires me to request read receipts for every mail I send. But no other email recipient requires this (as a matter of fact, i have received complaints for requesting a read receipt for a "hi how are you doing" kind of message). So, I was wondering, is there a way, like a plugin or advanced config, to filter the address list to which i send a read request? I can find only for "All mail I send" on outlook preferences. I've been searching on how to do this, but I couldn't figure it out.. Thanks in advance!
