I'm just facing the same problem today, it had been working fine a couple of
days ago. It appears it happens only when creating a entry from scratch, as a
bypass I did a Ctrl+drag of an old entry into today's column.

Spontanious issue: today I attempted to create a new apporitment by pasting
an item into the subject line. The item probably contained some HTML.
Received error message: "Could not save item. Out of memory or system
resources. Close some windows or programs and try again."

Is it a cooincidence that this occured one day after DST change?

Have tried diagnostics, windows update, creating new calandar (same
problem), checked system resources (plenty of memory available), virus scan,
and reboot.

Anyone else having this problem? Fix?
Thanks.
