how to force Mozilla 1.7 to rebuild all email index/summary files?

Mozilla 1.7 on Windoze, specifically the email client.

Through a handful of bad moves, I've corrupted my email folders on
Mozilla, and am trying to get it to rebuild the .msf summary/index
file. So far I've deleted all the .msf file (per a bugzilla post I
found regarding a similar issue on 1.5), and panacea.dat too.

Still, after deleting such (with Mozilla not running, or course), when
I go back into the email client, I see all my folder, but non of them
show to have any email in them. Also, the cursor changes to the
hour-glass, but Mozilla doesn't show to be using any significant
processor time in the task manager, and expanding my email directory
trees works fine. Mozilla recreates the .msf files, but they're of
zero length. I inspected the email files directly from the disk, and
they appear fine... look to be mbox, and have email still in them.

Anyone know I can force Mozilla to rebuild all the indexes/summaries
to see all the email that's in these files?

TIA

 

Self follow up...

Mozilla has a problem when the profile/data folder is on a path that's
mapped as \\COMPUTER_NAME\SHARE_NAME\PATH, rather than D:\WHATEVER.
I'll be submitting a Bugzilla report once I have all my email cleaned
up.
