Incoming Email Attachments from one sender turn to gibberish

[Bill174]

I have one correspondent whose email attachments are turned into
indecipherable gibberish when they appear in my inbox.
The documents or videos that he sends are attached, not inserted into the
body of the email, when he sends them. However, when I receive them there is
no attachment, but a large block of gibberish text appears in the body of the
email.
This sender is listed in my Safe Senders list. He claims to have made no
changes in his email program and his other recipients are not getting this
result.
What am I missing?

Hi Bill. I'm having the same issue. Are you running Vista? If so, it's a
security fix. I've reinstalled Outlook, but it did fix the problem. If you
make any progress, please post and I'll do the same.

You're missing details like Outlook version, account type, and Windows
version.
