Bouncing emails

From time to time I receive emails from customers with a from line like (details slightly changed for privacy):

outlook_8AXXXAD33XE4FC05@outlook.com

Replying to these is pointless as the emails bounce with an error message of

BN7NAM10FT040.mail.protection.outlook.com rejected your message to the following email addresses:

outlook_8AXXXAD33XE4FC05@outlook.com
A communication failure occurred during the delivery of this message. Please try to resend the message later. If the problem continues, contact your email admin.

BN7NAM10FT040.mail.protection.outlook.com gave this error:
Requested action not taken: mailbox unavailable.

I am just wondering what is the cause of the email address in the customer’s email to be shown like this?  I am fairly sure that the customer never entered this, so suspect it may have been “auto-added” by outlook perhaps due to some incorrect email setup ?

Those are spam and possibly phishing emails. Your customer’s name has been harvested from somewhere. It is very easy to assign a bogus reply address to a valid name. Bad guys do this all the time. You are better off just deleting this type of email.

Jabeatty, thank you – I think this is exactly what I noticed this morning.

Nice to see it’s taken nearly 2 years to not provide a fix, assuming lack of updates to the article means it’s not fixed.

cheers, Paul
