Sent Items Not Populating

[paladin2019]

I have checked the check box under Preferences -> Change Settings -> Save a copy of each personal message in my sent items by default. However, when I select Messages --> Sent Items, I get

Database Error
Please try again. If you come back to this error screen, report the error to an administrator.

So, I'm trying to report the error to an administrator.

I'll look into this. Thank you.

Ditto for me.
