Error received in the logs when performing an admin batch migration with Notes Migrator 3.2+:
"ERROR: [4951-33-85-00000108] Unable to migrate message
Unable to export message body.
MailGetMessageBodyText(C:\DOCUME~1\ADMINI~1.MCE\LOCALS~1\Temp\0D70E9D6.tmp):
File cannot be created"
When NME migrates messages with attachments, it copies the message and attachment to the %temp% folder on the NME console. When there is not enough space to extract the message/attachment to the temp path, the error occurs.
Change the %temp% path in Windows to a drive with more space. Then, attempt the migration again.
