This is definitely an issue *not* Leopard related.
This thread is closely related to the "
To use your Windows files directly in Mac you should reinstall Parallels Desktop." and "Leopard - Outlook - Error Message" threads.
I have the same issue, and I'm crossposting so the maximum number of people can read it.
This is using
OS X 10.4.11
Parallels 5584
WindowsXP SP2
Outlook 2003
The events that caused Outlook attachments to be unable to opened by Mac applications are as follows:
The user's account was a local account, but I needed to convert it to a Network account unfortunately the shortname was the same. So I followed these steps I found on the Internet:
I renamed the user's home folder for existing local account
I deleted the local user's account (to remove it from the Netinfo database)
made the new network account
I rename the user's home folder back to the original shortname
I did a "chown" command on the folder like this:
sudo chown -R username:staff /users/username
Everything seems to be fine except for opening attachments directly from within Outlook, unless you use a Windows app to do so. If a Mac app is assigned to open the attachment, we see the same error as Old Marine does:
"Parallels Desktop cannot open file
C:\Documents and Settings\Administrator\Local Settings\Temporary Internet Files\OLKF5\DocumentName.doc from the guest OS. You can open only files located on Windows drives (volumes) which have drive letters assigned or in Parallels Shared Folders".
I believe this to be a permissions error. I have checked the permissions on the C drive alias, and "Others" was set to "Read Only". I tried setting it to "Read & Write" and rebooting Windows and restarting Parallels, but that didn't work. The Group permission is still "Read only", but I don't know what group these aliases should be.
Someone on the forums suggested deleting these aliases and letting Parallels recreate them, but I'm a little nervous about that.
I also tried:
reinstalling Parallels Tools
disconnecting all Shared Folders, restarting Windows and reenabling them
If the files are on the Windows desktop they open in Mac apps fine, just not from within Outlook which is what the user expects to do.
