I am using OE 6.00.290.2180 (xpsp_sp2_rtm.040803-2158).



Recently, having been prompted to "compact" I did so and at the end of the
process I lost a period of four months emails (from Feb to June). It kept my
last few days emails.



Why did this happen (has never happened before in nearly 8 years of using
OE) and how to avoid it happening again?



Thanks
