I have presently 4 .pst files each 10 Go and outlook is working well with them, but I want to switch to a non MS application. However the size of the outlook .pst file for the same emails transformed in Thunderbird format is considerably bigger. Is there an improvement in the said size in the new update? Thanks for your answer.

I don't understand! Thunderbird does not use PST files at all. SO there can be no change in their size from Thunderbird importing the mail from outlook.
