Can't attach zip files to Outlook 2010 email messages

Last Modified: 2012-05-11
I'm running Office 2010 under Windows 7 64-bit. Outlook will not let me attach zip files to outgoing email messages. Outlook sees the zip file but will not attach it. A web search (sadly nothing on EE) had methods to overcome this by registering zip files, but the command recommended applied to Vista and doesn't work in Windows 7.

Sounds like somehow the component in Windows that supports zip-files is not properly registered.
To correct this you can reregister the correct dll via;
Start-> Run; regsvr32 zipfldr.dll
In some cases you’ll need to restart your PC for changes to take affect.

Do you get any error messages?


This is the same solution I found by Googling the problem. A screen shot of the error message I received in both cases is attached. error message

Do you get any error messages when trying to attach ZIP file in Outlook?

Try regsvr32 %windir%\system32\zipfldr.dll

Also check to make sure the dll is in %windir%\system32\

I've done a few tests just now and the following seems to be true. I create my zip files with WinZip. Previously, when I attempted to attach such a file to an Outlook email, the following occurs. Outlook sees the file, and I can highlight it, but it does not appear in the file name field. If, however, (and I haven't been doing this, but did it now), I use the WinZip program to send the file as an email, it works just fine. So I guess I don't have a problem after all. However, here's what's really strange. I just created a few trial zip files with WinZip, and Outlook will attach those. I'm a little baffled, but I guess the problem is solved. Because stas zed got me on the right track, I'm going to award the points to him.


stas zed bot me on the right track, so I'm awarding the points to him, although my testing led to another solution.
