NoReplyAll - The functionality does not grab all incoming emails RRS feed

  • Question

  • Dear All,

    the intent is to roll this addon out to all users in a global company, where no one besides key management staff shall be allowed to reply to all.

    Therefore it would be installed, the settings set to "Disable reply all for all received messages" and traces of the tool hidden as best as possible, i.e. the ribbons.

    I have tested this addon on my system (running Outlook 2010), and it seems that the Reply All functionality is not automatically blocked in 100% of incoming emails.

    The majority are, but some emails get through where Reply All is still clickable. We don't seem to be able to identify any differences between the emails which would allow for these instances where emails retain the ability to reply to all function.

    Are there any experiences with this issue? Any idea how overcome this?

    Thanks in advance,

  • Hi Patrick

    This isn't something I've seen myself, but I'll take a closer look.

    I do want to alert you to the fact that this add-in is not a reliable way to prevent people from responding to emails - it is actually not difficult to re-enable reply all via Outlook's built in VBA, and other email reading clients (Outlook Web Access, or Outlook on Mac or phone) ignore the settings. Or, of course, the user could disable or uninstall the add-in.

    I've not read it in detail, but http://blogs.technet.com/b/exchange/archive/2009/09/29/3408403.aspx looks like it might be closer to what you want. Since it's GPO based, I think it's something you can remotely deploy too (though I confess I know almost nothing about GPO admin). Another approach, which I've mentioned elsewhere, is to use IRM, though that is something the sender needs to do for each email rather than apply as a global setting - http://office.microsoft.com/en-us/outlook-help/prevent-e-mail-message-recipients-from-using-reply-all-or-forward-HA001114224.aspx outlines the process.

  • Dear Gavin,

    thanks for the quick feedback.

    I was aware that this add-on is more geared towards the user rather than the administrator, but did not find any better solution.

    We would have hidden the ribbon as best as possible and hoped for the best. :)

    The average users probably might have been fooled by that.

    Yet, the link you supplied would be a much easier solution. I am currently looking into whether our Exchange host company can / will do that for us. Much appreciated.

    If you find anything relating to the issue I mentioned above I would still be interested to hear about.

    Thanks in advace,

  • Incidentally, if you're really determined to use something like the add-in, and if you have (or can get hold of someone with) experience of .NET programming, perhaps you could roll your own customised add-in, with no UI for example - I've outlined the process of making this one on my blog.

    The original idea behind the add-in is described on Scott Hanselman's blog, and one of the initial triggers for writing the add-in was to create a reasonable UI for that. I've not investigated, but perhaps you could get the effect you want via VBA, which might be simpler programming.
