Do you know what the trickiest part in any endeavour to export olm database is? It is converting the metadata exactly as it exists in Apple Mail. If you don’t know what metadata is then we must first apprise you with what it is. Metadata can literally be translated as data that is beyond the data. In simpler words, it is that data which describes the main body of data. What we usually know as the SMTP headers are a part of it.
When we export exchange OLM to Mailbox, most data is completely converted to mbox. While most converters do a pretty fair job at conversion, not every conversion has the ability to treat the metadata in fair way.
