Enabling Reply To All in Outlook - version 2

I previously described how to enable Reply To All in Outlook. Since then I've modified the VBA script so it works on both Office 2003 and 2007, gives better error messages, automatically replaces the disabled Reply To All buttons, allows editing messages (even if that feature has been disabled) and strips messages of inline images. Installation instructions and links to the code are in the user manual:

I don't want to duplicate the installation instructions here, as I will likely revise them over time. However, at the bottom of the manual is a plea to Outlook administrators not to disable Reply To All in the first place. I don't think arguments against disabling essential email functionality can be made often enough, so here is my plea:

Plea to Outlook Administrators

Please do not disable essential email functionality. With the workarounds linked to above, the attempt is futile, but remains deeply inconvenient. Consider the situation where Alice sends an email to Bob, Charlie and Dave asking for some financial details of Mega Corp. Bob has the details on a post-it note on his desk and quickly replies to everyone with the information. But in a world without Reply To All...

• Bob replies just to Alice. Charlie, being the helpful soul he is, decides to search through the filing cabinet for the information. 15 minutes later Charlie finds the details and emails Alice, only to be told "Thanks, Bob answered this 15 minutes ago". Charlie realises he just wasted 15 minutes of his life, and goes to get a cookie to make himself feel better.


• Bob replies just to Alice. At the end of the week Dave is reviewing his emails and realises that Alice still hasn't got a reply, but before he potentially wastes 15 minutes, he drops Alice an email - "Do you still want those details?". Alice replies "No". Dave concludes that he's a clever bunny for not going to the filing cabinet, and decides a one week latency when replying to Alice is just common sense.


• Bob replies, but realising the potential cost of replying just to Alice, also replies to Charlie and Dave. Bob spent a minute retyping the recipient list, and wonders "Why can't Outlook have a button that does this for me?".


• Bob replies, also including Charles and Dave. Woops! That should have been Charlie, not Charles. As a best case scenario, Charles gets annoyed with a useless email, but at worst Charles brings down Mega Corp with the sensitive information gleaned from the email. Charlie still ends up going to get a cookie.

Removing Reply To All increases the volume of email required, and increases the risk of email accidents. I've heard only two arguments against Reply To All, both of which are wrong:

• When Bob replies to everyone, the financial information about Mega Corp gets sent to Charlie, but what if Charlie shouldn't have access to that information? Of course, if Charlie shouldn't have access to that information then Alice was at fault for sending the request to Charlie in the first place. Bob should also check when sending sensitive information, but most emails are not sensitive (it is a poor default), checking the senders should not require retyping the senders (it is a poor user interface) and by default mailing lists are not fully expanded (so he won't be able to tell the full list of senders anyway).


• When Zorg, the owner of Mega Corp, sends a Christmas email to all his employees, what if one of them hits Reply To All? That wastes a lot of company time, and should be prevented - but not on the client side. It is possible to restrict the number of recipients to an email, Zorg could send out the email with everyone in the BCC field, or IT could set up a mailing list which does not permit replies.
