Attachment.ashx Message when Opening Attachment in OWA Exchange 2007


Message window hangs when trying to open or save attachment using Outlook Web Access (OWA) with Exchange 2007 on a Vista computer with IE7 (Internet Explorer 7).


Attachment.ashx Error Message when Opening Attachment in OWA 


I recently ran into a situation where all of the users in an Exchange 2007 organization environement were able to open attachemnts using Outlook Web Access (OWA) against Microsoft Exchange 2007 server without a problem except for a few.

One of the users that wasn't able to open, run, or save an attachment using OWA was getting a message that said:
Geting file information: attachment.ashx from mail.{servername}.com
The message included the flying paper from left to right - the usual animation seen when transfering files in explorer or downloading files with Internet Explorer. This messgae would be displayed but would never go away and of course the user could open, save or viewer the attachment through Outlook Web Access.

Run Attachments from OWA Email

Well, if any of you encunter this problem and think there is something on the Exchange server that could fix the problem don't bother wasting your time or making any settings changes as the solution won't be found there. You've probably already drilled down and found some of the differences with the user's computer that isn't able to open attachments with Outlook Web Access and commonalities with those users that could view, save, or run attachments through OWA. If the trouble computer has another browser on it like FireFox, try that browser and you'll see that FF works and since it works, then the server or the users accoount in the domain has nothing to do with the problem.

Windows 7 with IE8 

If the problem user ... I mean the problem computer, is Vista with IE7 then the setting that is most likely causing the problem for you is the one located in the Security cetegory under the Advanced tab after clicking Tools > Internet Options from the Internet explorer menu bar.

Do not save encrypted files to disk 


Un-check the box next to the setting 'Do not save encrypted files to disk". Once un-checked and the option is saved, open a new browser window and then try to open or save the attachment in Outlook Web Access again, you'll probably have better results.

Remote Support Software

For web based remote access and computer remote control for remote support, try remote support software that doesn't cost an arm or leg to purchase and use. The name brands have many bells and whistles but are over priced for basic remote access for desktop remote control on the web. Appliance based online computer remote support software solutions and tools tout lower cost because you own the box but you pay maintanence fees and for support that's almost as expesive as the original purchase.

Nice post. In IE7 running on XP, the message is different.

Mike said...

This issue can also occur in Windows XP running IE6. Some anti-virus programs now recommend setting this security feature (I'm running Kaspersky, and that is what caused the trouble.)

Thanks Mike for pointing out an IE6 on XP deployment can also have this issue and an altermantive for solving it.
I have found that it's not very common. I had it happen on a Vista system with IE7 and this post solved it for me. Previous to this post I had disabled anti-virus software as a suspect cause for this problem.

I suppose that I have enough wide knowledge about MS Outlook. But I was wrong and I was forced to use the determination for my issue at the Inet. As luck would have it I was succeeding and found out an one utility. It was effective and I thing might be as much useful - microsoft convert ost to pst.

I was wondering why some groups of users were getting this error and not others.

The original post solves the problem regarding the attachment.ashx Unticking the box in Tools, internet otions,advanced etc.. worked first time when using outlook in microsoftonline when downloading an Excel workbook. Why Microsoft do not supply an answer to this on their website is beyond me. Anyway thanks to 2 cents

Same kind of error with OWA on SLED 10.

"Microsoft Outlook Web Crap" is more like it... We never had any problems with Thunderbird (which in our organisation was replaced by MS OWA - big mistake, if you ask me)

I glad 3 years later the post is still helping people out there solve this weird problem. PLEASE PLEASE LINK TO IT, BLOG IT, Favorite it, etc. That will help others find it faster. My post are found in search engines but it would be easier if they had more people like yourselves who have found this and other posts useful to point to it. I think many can agree that often the worse part of finding a solution is the time used up to weed through search results. I didn't even have that luxury, I just had to figure out the solution live!!
PS. doing an exchange 2003 to exchange 2010 migration soon (did already two to other installs but they were not migrations). I hope to get some good information for others who may be endeavoring to install or migrate their exchange email.

If you facing attachment download problem with IE 8.0, then do the below specified settings Tools-> Internet Options-> Advanced-> Security -> Check for signatures on downloaded programs(un check the box)and save the settings.IT solved my problme.

Thank you for the help! I think Kaspersky caused my challenge (with my help of course), but this worked.

I recently have this problem on Ubuntu 11.10 with Chrome as well as Firefox! All attachments are named bttachment.ashx when downloaded. It used to work fine! Perhaps they did some upgrade or patch on the OWA server....

Thank you. This solved my problem!!

I am running Windows 7 and IE9. My OWA attachments would always show as long links starting with the filename attachment.ashx

Thank you so much, it worked. I was desperately looking for a solution and your way solved my issue in 2 minutes.

Until a couple of days ago I was happily opening attachments to emails received in my MS Outlook Web App. Then for what would appear to be no reason no such luck and just kept getting messages that my pc was trying to open or save attached files with an _ashx string. I run on Vista SP2 with an up-to-date Windows IE and after following the guide above all was sorted without any further ado. Thanks
