That has worked. Thanks. What a strange problem.
Now (1) compact all folders in the old identity, (2) import messages from
the old identity into the new one, and then (3) delete the old one (File >
Identities > Manage Identities).
To avoid such corruption in future:
- Don't use Inbox or Sent Items to archive messages. Move them to local
folders created for this purpose.
- Empty Deleted Items folder daily.
- Disable Background Compacting [not available in SP2] and frequently
perform a manual compact of all OE folders while "working offline". More at
http://www.insideoe.com/files/maintain.htm
- WinXP SP2 only: Do not shut down your machine while Windows is
automatically compacting your message store.
- Your anti-virus application's email scanning feature can also cause such
corruption. Disable it. It provides no additional protection.
