Hello,
I just set up an Outlook.com and SkyDrive account recently and I've been trying without ANY success to share a folder with some files in it with a friend. Every single time I've tried to send it I get a return delivery delayed error message, usually twice, and then ultimately a failure message with a copy of the e-mail I tried to send.  This is a copy of one of the failure text messages I got with one of the returned e-mails:

Reporting-MTA: dns;col0-wss1-s5.col0.hotmail.com
Received-From-MTA: dns;BAY179-DS11
Arrival-Date: Wed, 9 Oct 2013 06:02:55 -0700

Final-Recipient: rfc822; *** Email address is removed for privacy ***
Action: failed
Status: 5.6.2
Diagnostic-Code: smtp;554 5.6.2 Delivery SMTP Error. Command: 3. Response: 535 5.7.8 Error: authentication failed: authentication failure
. Type=1 (-956218626:896:-2147418113)

In my SkyDrive it says that my folder is indeed shared with the person whom I intended to it it with, but they never received the e-mail with the links to the folder/files.  I tired sending it to two different e-mail addresses for him and both show up in my SkyDrive account under "Shared" but they never got any of the e-mails.  All were returned to me!

Also, he happened to send me an unrelated e-mail and I answered it from Outlook.com and he never received it.  That was returned to me as well.  What the heck is going on?  HELP please?

Thanks.
Maria

Get with the times here MS.

 Obviously there is a desire/ need for this feature.

 If a "read" mail indicator is available for POP 3 accounts, I find it very hard to understand why RTS (return to sender) does not exist.

If this is a technical issue then explain.

Better yet, simply EXPLAIN why not - period.
