my mail recipients cannot open attachments

When I send an email using Outlook, my recipients tell me that they cannot open my attachments.  This isn't happening with all my recipients, but with most.  It happens with word attachments and pdfs.

A couple of options:
1.  the recipients may not have Word or Adobe (or the readers) installed on their computer.  This usually affects home users vs. recipients at a company since alot of home recipients may not have these applicatons installed on their home computers.    They could install the "viewers" if they don't.  Here's a link to download the Office viewers  http://office.microsoft.com/en-us/downloads/HA010449811033.aspx
2. Do you have"Word as your email editor" as an outlook option?  Switch the message that you send to HTML type to see if that helps.   If they have Outlook Express and not full Outlook, this could be the problem
3.  Are you sending via Office 2007.  If s they may have to installthe 2007 viewers.

These options may not be the problem but they are something to look into.  If this isn't the problem, Do you have any error messages to add or any other details?

In my experience most common reason for such a problem is mail sent from Outlook when format is configured to be rich text format TNEF. When you send e-mail to recipients using Outlook and some other e-mail software, TNEF is processed correctly and that is why some of your receipients get it right. It is possible to configure Outlook to send e-mail in plain text or HTML to resolve the issue. Two scenarios possible: global setting when you configure it for all your recipients or configuration per recipient. Here is Microsoft link about the subject and instruction how to change your configuration: http://support.microsoft.com/kb/290809
you would need to tell each user to go under their email settings under Tools>Options>Security Tab>, and uncheck the box where it says Do not allow e-mail Attachments to Read/Save. i am 90 percent sure that will fix it.  let me know if you need anything else!!


All my recipients have MS Office 2003 or 2007.  I am using MS Word as my email editor and I am sending via MS OFFICE 2003.  They receive other people's word and excel and pdf attachments, but not mine.  When going to tools options security there is NO SUCH check box available.  ARGH

Could you provide more details you would think are important to troubleshoot this issue ? What message get your recipients exactly ? Is that "Corrupted file" or "Unknown file type" or something else ? Anything else ?


One of two things happens.  They get "corrupted file" message or in some cases they can open the file for about 30 seconds and then it shuts down.  the program.  This happens whether I send a original document from my desktop or if I forward and email with someone elses documents attached.  I had one recipient with GroupWise that could open the documents just fine.  The others with Outlook also, could not.  Kim

It was the firewall.  I was using CA EZ Armor.  I then discovered from Microsoft tech support that because I am using a linsys router to access the internet and am not directly cabled to the internet from my computer, that I don't even need a firewall.  Removing it has helped in so many other ways in addition to my email fix.
