To verify that you are not sending emails in Rich Text in general go to: The options to prevent sending out Rich Text emails are a bit scattered throughout Outlook since it can be controlled at Outlook, Contact and Message level. The best thing is to never compose your messages in RTF-format as you can only really rely on this format when you are in an internal Exchange environment with only Outlook clients but that is a whole different technical story of its own. I've tried turning off my anti-virus program but that's not made any difference, so I'm assuming the issue must be within Outlook itself.Īnother common reason for this to happen is when you are sending in RTF-format and the message doesn’t get properly converted to the HTML or Plain Text format.Įspecially in the cases where they receive a winmail.dat attachment it is very likely that Rich Text is to blame here but it can be absent as well. If I send the same attachment through web mail or from another computer, the attachment remains intact and is received in the email. It happens to all attachments regardless of who I send it to and the format of the file (e.g.
You may need to increase the window size if you don’t see these buttons.Whenever I send an attachment through Outlook, the recipient receives the email without the attachment although they sometimes say that it got renamed to winmail.dat.
As long as the sender and recipient both have mailboxes in the same Exchange organization, and as longs as the recipient is using the Outlook email client, these settings settings get passed along.Īfter installing NoReplyAll, you’ll notice extra buttons at the end of the ribbon bar on a new email message window.
Going back to our article’s focus, the email recipient doesn’t need to have this add-in installed to have reply all disabled. Microsoft Office applications, such as Word, Excel, PowerPoint, and Outlook can be used to create and consume protected content. In addition, it protects supported attachment file formats and allows you to configure expiration of email messages and attachments so that they can no longer be viewed after the specified period. On the other hand, using IRM allows you to prevent an authorized recipient from forwarding, modifying, printing, faxing, saving, cutting, pasting or even taking screen captures of content. It also requires a much more complex setup and configuration. As stated above, IRM is a much more robust technology that is integrated with Exchange Server 2010/2013 and Active Directory.
If you want a mechanism for protecting your emails in a much more secure and robust manner, then use the IRM facilities that Exchange Server offers. This means that this type of mechanism is very weak and only partially useful and shouldn’t be used if there is true need to restrict distribution of email messages (for legal reasons, for example). In addition, the recipient may enable or change these settings if they want to, even without the permission of the sender. Note: Although this feature is handy for people working mostly with email that is internal to the same organization, it does not work for external recipients that are using other email clients. The add-in also includes a check for common email errors, such as omitting attachments or subject lines. The add-in uses a facility built into Outlook and Exchange that’s more lightweight than Information Rights Management (IRM) and doesn’t require any type of back-end configuration from the IT department.Īfter installation, it adds a few buttons to the Outlook ribbon that allows a user to control the recipient’s ability to reply to all recipients in your email message, forward it, and so on. A developer at Microsoft Research named Gavin Smyth in Cambridge, UK, has created a neat, but little-known Outlook add-in utility called NoReplyAll that prevents people from replying to all the recipients of a message or forwarding it.
