Save the file to a folder. Go to that folder and select the file. Shift-right click. Chose Open with ...
Select your favorite program to view tiff-files with and take care to check "always use this program to open files of this types". This need only done once, and then you will be able to open the attachement itself, I think.
Programs to try:
- Internet Explorer
- Irfanview (download from www.irfanview.com)
- Microsoft Photoeditor
- Adobe Photoshop
Hope this helps. If not, post again with details about what goes wrong.
I run window XP pack SP2. I can't open files with extension tiff in my incoming mail. I tied outlook help but I didn't find anything helpful. Does somebody knows the answer to my problem? it is very important for me since I run a business from home and I get all my faxes by mail and I can't open them.
