Why do you use ‘read receipt’ in outlook?
-
Confirm that the mail is read
-
To remind the recipient about the mail
-
To know whether the mail is deleted without being read
-
Both (a) and (c)
Read receipts notify senders when recipients have opened their emails, providing confirmation that the message was viewed. This feature helps track important communications and verify message delivery. Recipients can choose to allow or block these tracking notifications.
In Outlook, requesting a 'read receipt' does two things tied to the same flag on the message: if the recipient opens it, Outlook prompts them to send a receipt confirming the message was read; and if the recipient instead deletes the message while it is still unread, Outlook prompts them to send a receipt stating the message was 'deleted without being read.' Both notifications are opt-in on the recipient's side and only appear because a read receipt was requested — without that request, no such prompts occur at all. So requesting a read receipt lets a sender potentially learn either that the mail was read (a) or that it was deleted unread (c), making 'Both (a) and (c)' the accurate description of the feature's purpose.
