Reconstruct and guid mismatch

[Nicolas GIMMILLARO]

Hi,

When using reconstruct or chk_cyrus, i get error messages related to 
guid mismatch for each folders in each mailboxes.

I tried different options (-G  , -R) with reconstruct, but it changes

What is GUID ?
How is the mapping between UID and GUID made ?


Thanks
