Thanks for your advice.. I managed to do the same... imported .dbx into Thunderbird format. Converted thunderbird to .EML using some free utilities. And then finally imported the emails to O2010. Just that my .dbx was 9.82GB (10GB being the limit), perhaps it was crashing everytime I was importing it directly from OE to O2010 via MS Exchange.
Appreciate your writing back.
Thanks & regards.
