Roelof, Bingo! I had deleted the messages.tbi, but not the .tbb. As it turns out, it was the SENT folder that was the problem.
To your reference to "How often do compress your folders?", I have it set to empty trash and compress on exit each time... maybe three or four times each day. I maintain the size and number of entries in all those folders to a minimum, keeping a rolling seven days in each account. Older messages are archived and stored to another backup/archive server. Thanks for the quick response and a great product for over three years. First problem I've had with any version. -- Thank you, Alan mailto:[EMAIL PROTECTED] -------------- Using The Bat! v1.61 on Windows 2000 5.0 Build 2195 Service Pack 2 *********************************** Wednesday, October 2, 2002, 5:54:36 PM, you wrote: RO> Hallo Alan, RO> On Wed, 2 Oct 2002 15:58:21 -0500GMT (2-10-02, 22:58 +0200GMT, where I RO> live), you wrote: AP>> Currently, all other accounts are sending and receiving mail fine, AP>> but one account cannot send.
