Where is this Preview function on an attachment. In OL2003, I only see
the following context menu selections with right-clicking on an
attachment:
Open
Print
Save As ...
Remove (disabled)
-------------------
Cut (disabled)
Copy
Paste (disabled)
-------------------
Select All
If I double-click on the attachment, I get a dialog window with the
choices to Open or Save.
Open is going to extract the long text string (decode it) from the MIME
part in the body for the attachment's content. It then has to save it
somewhere to pass that file to the handler. For the Open action, it
saves the extracted attachment in the Outlook secure temporary file
folder. It's possible that this folder has filled up (there is a max
size for it configured in the registry). That's usually because Outlook
didn't gracefully close the file to release the file handle and delete
the temporary copy of the file.
Do you have problems opening (previewing) attachments of different
filetypes that are the same size, or larger, as the psd attachment? You
cannot Open an attachment to create a file that is larger than the free
space in the limited-sized Outlook secure temp folder.
If you need to clean out the Outlook secure temp folder because too much
left over crap is occupying it, first figure out where is this folder.
To find the folder name, look in the registry under:
HKEY_CURRENT_USER\Software\Microsoft\Office\<version>\Outlook\Security
where <version> is whatever version of Outlook that you installed; e.g.,
10.0 for Office XP, 11.0 for Office 2003, and so on. The data item
named "OutlookSecureTempFolder" points to Outlook's temporary file path.
Exit Outlook, go into that temp folder to delete any remnant temp files
still in there, and then reload Outlook to Open the attachment.
For Outlook 2010, see:

I doubt Microsoft has included an in-built viewer for every possible
filetype that can be an attachment to an e-mail. So while previewing
works for the viewers that come with Outlook, you need to use an
external viewer for filetypes that Outlook cannot handle. Perhaps if
the viewer's installation added an add-on to Outlook to handle the PSD
filetype then it would preview inside of OL2010.

I missed which version of Outlook that you have I don't have OL2010 but
my guess is Preview means to preview inside of Outlook and Open means to
pass to the handlers associated to the filetype. From the snapshot of
the context menu shown above, it looks like you use Preview when the
attachment is a filetype that the in-built Outlook viewers can handle;
otherwise, use the Open action to extract and pass the attachment to an
external handler.
