You can easily split the archive file in many other and smaller archive files you want !
Open the archive file or the mail box to archive
Set the archive parameter with a new file archive name, let’s say “PART1_”+YourOrgineNameFile+”.NSF”
Archive the documents you want (let say the half) in this new archive file (it will be created automatixally)
Set the parameter again with a new file archive name, let’s say “PART2_”+YourOrgineNameFile+”.NSF”
Archive the others documents you want (the other half) in this second archive file
After that, you could burn the PART* file on DVD and delete the original Archive file
