[Evolution] A bit of information re folders 'losing' emails and a couple of questions

[Reid Thompson <Reid Thompson ateb com>]

Randomly, folders with hundreds or thousands of emails will begin
displaying in Evolution with only a very small subset of the folder
content.  Ex:  I have a folder with over 5K emails in it.  Today, it
started displaying only 26 emails.
This is with Exchange OWA.
I quit evo, did a force-shutdown and cd'd into the folder's directory
and rm'd the summary file ( it obviously appeared to not have a summmary
of all of the emails ).  I then restarted evo.  Evo rebuilt the summary
file correctly and again displayed all ~5K emails.  

What causes the summary file to be modified?  

Is there a mechanism to force a re-generation of the summary file w/o
the steps above re rm'ing the file?


I recall a bug or bugs being posted for this, but I couldn't get the
right combination of search words to pull it up to add this info...
