OWA will sometimes take WORD and EXCEL documents sent as attachments and
compress them. The recipient is unable to uncompress the attachment into the
original application type document, but instead is left with xml documents
that reflect formatting and content information. Can the original be re
constituted? What promts OWA to compress some OFFICE DOCUMENTS and not
others?
 
Are they unzipping them or renaming them from *.zip to *.docx (*.xlsx) ?
The *x files are zips - the extension just needs renamed back to docx or
xlsx.

The admin can fix it site wide by adding the office 2007 file types to the
MIME settings on the server. This will tell the browser how to read it.

On the user side, IE has an option to open files based on content not
extension - add the owa url to the trusted (or local intranet) list and
disable this option. It's in IE's tools, options, Security tab, trusted
sites - look near the bottom of the Custom level. This should not be
necessary if the mime settings are corrected.

The attachment appears as a docx or xlxs extension, but when it saves, it
saves as a .zip.

Do you have a zip program like WinZip installed on your PC? Perhaps that's
causing the change.
 
I am a little late in responding.. it worked. Thank you

trying your solution out on a message on a compute across town tomorrow... If
it works, or does not work, I will let you know. Again, you have always been
very responsive to my questions.

Thank you for the input, but it was as Diane noted, the Internent Options
needed to be changed to allow files to be run according to their extensions.
