Problem: When you open the Insert File dialog in when composing an email message, Outlook "hides" the zip files in the directory. The only way to add a zip as an attachment to a message is by opening Windows Explorer and dragging the file to the message window.
Cause:
Windows has a system component that treats zip files like ordinary file folders and Outlook sees these files as folders. In most cases, it only happens when you don't have third party compression programs installed, so you may see the behavior on one system but not another.
Reasoning:
Under certain conditions, the Windows shell will include a folder attribute for zip files. This result is cached, thus Outlook will exhibit the same behavior throughout the session.
Solution:
Restart Outlook or if it happens often, Disable Compressed folders. If you use a third party program (such as WinZip) you can leave compressed folders disabled. Note that disabling compressed folders will also disable XP searching in ZIP files when searching for files.
To disable the feature at the Start menu, Run command, type:
regsvr32 /u zipfldr.dll
regsvr32 /u cabview.dll
To restore the functionality, return to Start Menu, Run command and type:
regsvr32 zipfldr.dll
regsvr32 cabview.dll
Those instructions are for Windows XP - the instructions for Vista and Windows 7 is more complicated to disable and re-enable.
You need to open regedit, browse to HKEY_CLASSES_ROOT\CLSID\{E88DCCE0-B7B3-11d1-A9F0-00AA0060FA31}, export the key then delete it. I'll write up the complete instructions.
If you don't want the hassle of editing the registry, you can open Windows Explorer and drag the file to the message - drop it anywhere on the message.
I use windows 7 and outlook 7 and outlook 7 can not "see" zip files when I want to insert/attach a file.
