Outlook 2010 NDR With mailto: addresses

Posted on 2012-09-22

This is a little frustrating and i'm wondering if any one can help.
When my users (Win 7, Office 2010, fully patched) inadvertently click on or reply to an email address that is using mailto: they get a NDR.

Not sure what the best course of action is. I have come across the MS Hot Fix for this issue in Office 2007 but not for 2010.

I would think I either need to change something on the Exchange 2007 box or look to block the mailto: on the client pc.

Any thoughts?

    Just to make've checked these, right? or possibly

    Yep, had seen both of those. I assumed the first one would not be applicable as it refers only to Office 2007. The second refers to how how word 2010 is managing email links and to be honest I didn't really find that applicable. (I've just reread this KB and it notes that there is not space between the mailto & email. I've just tried both in outlook and both came back with an NDR, although I could try the hot fix for the hell of it and see what happens).

    I'm specifically looking at Outlook 2010 / Exchange 2007 and how they handle the mailto: whether a user has clicked on an email link in an email they have received or maybe from a website.

    I suppose the question is. Can either Outlook 2010 or Exchange 2007 be configured to automatically interpret the mailto: and either process it or convert it into smtp data type?

    Hope that makes sense:)

    Are you sure the issue is when the users are clicking on a mailto link ?
    Does the NDR look like this ?
    #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

    Accepted Solution

    It's not necessarily just that although that is what has brought this up.

    I've just done a quick test on Outlook by typing the following in the address

    [] and also [mailto:](With and without the space mentioned in the MS KB).

    All I am getting back in the outlook client is

    Your message did not reach some or all of the intended recipients.

          Subject:      Test
          Sent:      22/09/2012 10:16

    The following recipient(s) cannot be reached:

 on 22/09/2012 10:17
                None of your e-mail accounts could send to this recipient.

    Which would possibly suggest something on the exchange 2007 side needs correcting?
    I probably need to have a look at the exchange logs in a bit.
