He is using outlook and I am using thunderbird. I then forwarded this message on to another colleague who is using outlook express. When she double clicked the attachement, excel opened up, displaying the code from the forward mail, rather than the excel file. Reproducible: Always Steps to Reproduce: see details I cannot provide the email for privacy reasons, but if you need to I can probably reproduce this with non-sensitive data.
Actually, it seems that this bug occurs any time you forward a mail message with a subject of .xls to someone using outlook express. Outlook express takes the attached message as being and excel file.
I think this is almost certainly an issue with OE and nothing to do with Thunderbird but some additional testing might be useful as I was unable to reproduce this bug correctly with Thunderbird and Outlook (I don't have OE to hand). Can you forward an e-mail as an attachment with a subject ending in .xls to OE and take a look at the headers. I'm expecting the attachment to be described in the headers similar to... Content-Type: message/rfc822; name="test.xls" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="test.xls" If the content type is indeed set correctly ('message/rfc822') then OE is ignoring the content-type and opening the attachment based on the file extention. This wouldn't be suprising and I'll then close this bug.
Yes, it is as you suppose.

I'll close this as INVALID since it appears to be an issue with OE ignoring MIME types and openning the filebased upon it's extention alone. Might be a good oppertunity to migrate your colleague to Thunderbird :-)
