I have a new PC with Windows XP and Outlook Express with all MS updates completed. I was sending large emails containing pictures to test what the limit my ISP puts on my email sizes. (It seems pretty huge, beyond 30MB even...) Anyway, when I went to try delete the Sent messages (because they are wasting space), my PC does nothing (no error, no popup warning, nothing) and the messages are still there. I CAN delete older messages that are small in size, but none of the newer messages. Just weird. Anyway, does anyone have a suggestion what to try? I can send and receive email just fine, but cannot delete email from any of the 30 or so folders I have.
