Occasionally we get email that should have an attachment but it doesn’t seem to be there.
One way you can check for any missing attachment(s) is by using a web browser to log on to your email account. However, any attachment(s) may already be downloaded to your computer. To find out:
- Select the email in question from within OS X Mail.
- Select the menu option File > Save Attachments…
- Navigate to the Finder location where you’d like to save any attached files.
You can now use the Finder to check that location for the attached files. There may be some extraneous files saved as well (e.g. signature graphics, html).
Although I haven’t been able to test it, the general theory is that MS Exchange Server is the culprit.
