Now, with Microsoft Exchange 2016 you can disable this so that mobile devices don’t automatically send these read receipts out.

This is bad for a number of reasons such as spam (this is a big one, where they try to validate e-mail addresses), legal reasons, you don’t have the time to respond and don’t want a read receipt sent yet, or you simply don’t send read receipts… This means that if someone sends you an e-mail, requests and read receipt, and you open it on your mobile device it will send a read receipt without prompting you or giving you a choice in the matter. Something that has bothered me for a very long time has been the fact that mobile devices (using Microsoft Exchange ActiveSync), automatically send read receipts if the sender has requested it without prompting the user.
