About The King

The King of MGD!A lot of people ask me what does MGD King mean? Well, it was a nickname given to me because I used to drink large quantities of Miller Genuine Draft. Someone mentioned to me that I was the King of MGD, and so it stuck.

Outlook 2016 Cannot Forward Attachments - KB4011626 Issue

by MGD King January 11, 2018 11:53 AM
We have just discovered an issue with Microsoft Outlook 2016 that is the result of an update from Tuesday, January 9th, 2018 (KB4011626). The issue is that a user cannot forward attachments that are in a text-formatted e-mail. You are most likely familiar with these types of e-mail messages from mulifunction scanners; the message is formatted in plain text and the attachment is a PDF file. The problem is that when you attempt to forward that message with the PDF document, the attachment is stripped. To work around this issue, until Microsoft releases a fix, is to save the attachment on your computer (your desktop or folder on your desktop) and create a new message, then attach the saved document. 

This issue seems to be affecting both 32bit and 64bit versions of Outlook, regardless if it's Windows 10 or Windows 7, and it does not affect Rich-text format or HTML formatted e-mail messages.

UPDATE: Microsoft has released a hotfix for this issue. You can download it here. Thanks to Per von Zweighbergk for contacting me on Twitter with the news on the hotfix.

Why not just copy and paste the attachment?   Or drag and drop from the original E-mail.   Saves having all those PDF's saved on your computer.

Yes,  you can do it that way. I just provided the most convenient way for "typical" users.

Works 100%, uninstall and block the update from installing.

Users were unable to forward attachments from the photocopier, which is a plain text email.  HTML and rich text emails work correctly.

Thanks for the fix!

You're welcome!

If this affects you in an enterprise setting, I'd be wary of blocking or uninstalling the update. From what I've seen, it's a cumulative security update. So by blocking it you're stopping other hosts from receiving what quite possibly is a critical update...And in doing so, a security 'hole' could be created. Microsoft themselves recommend that you don't uninstall the update and instead look at the workarounds like the ones provided here until they get in gear and issue a revised patch.

Good point! Microsoft put out the update for a reason, it's just unfortunate that it stops one of the most basic functions of Outlook.

Thank you for this.  I've been telling my users to suck it up as it's by design (original email plain text) but did find it weird I suddenly had so many reports of it.  Will be adding this update to the blacklist.

You can also go to more and select forward as attachment.

@ Marco, works if you have a single computer, what about our company with 1000 users? At the mercy of microsoft whenever they decide to release a patch to fix this ( which most likely wont be until Feb update)

Wow, great catch. Had this on one of five term servers with matching configurations. It was on the one server that got updated outside of our normal maintenance schedule.

What a bizarre symptom!


1/19/2018 8:27:47 AM #

We had the same issue but I wasn't too sure which update had caused the issue. You are a life saver!

After closing the message, I am able to forward the plain text message from the message list. The message is converted to HTML and the attachment is still in the message.

Good find.

Looks like Microsoft have removed the URL.

FYI: I installed the hotfix on a system and it stopped the network adapter from getting an IP address...  Removed the update and the network worked again...  Odd...

That's bizarre. I've installed the hotfix on several machines without issue.

Thanks! We're having this issue as well. I'm going to try the hotfix.
