Can you delete the oldest message in the Outbox? If not, download and
install this fix with Windows Mail not running:

Although it's labelled as for mail stuck in the Outbox, it also works in
other folders. If you don't know whether to use the 32-bit version or
the 64-bit version, try the 32-bit version first. Certain common
antivirus programs, such as most of those from Norton or McAfee,
or a recent one from Trend, tend to cause such problems, although
seldom immediately, so if you have such a program, remember where
to find the fix - you are likely to need it again.
