NDR generates when mailto hyperlink, #550 5.4.4 ROUTING.NoConnector ForAddressType

Written by

You may receive NDR something similar to below when sending emails from your Outlook 2007/2010.

'This email address is being protected from spambots. You need JavaScript enabled to view it.' (MAILTO:This email address is being protected from spambots. You need JavaScript enabled to view it.) IMCEAMAILTO-xxx%2B40xxx%This email address is being protected from spambots. You need JavaScript enabled to view it.>
A problem occurred and this message couldn't be delivered. Check to be sure the e-mail address is correct. If the problem continues, please contact your helpdesk.
Diagnostic information for administrators:
Generating server: This email address is being protected from spambots. You need JavaScript enabled to view it.

#550 5.4.4 ROUTING.NoConnectorForAddressType; unable to route for address type ##

If you give a close look, you can see mailto parameter in those emails are creating issues.

When we type an email address inside the square brackets after the Mailto: header, the email address is displayed as an incorrect hyperlink which causes the NDR to generate.

Microsoft has released hotfix for this issue and is available to download here,
