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. 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.
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…
Now, with Microsoft Exchange 2016 you can disable this so that mobile devices don’t automatically send these read receipts out. It’s a simple procedure using Outlook on the web (previously known as Outlook Web Access, a.k.a OWA).
To disable automatic read-receipts:
- Log on to your OWA (Outlook on the web) server.
- Click on settings (the gear) on the top right
- Expand the “General” settings menu, and select “Mobile Devices” (as shown below)
- Check the checkbox for “Don’t send read receipts for messages read on devices that use Exchange ActiveSync”.
