If you try to import an OLM file into Windows Outlook, following error appears,
Outlook for Windows supports Offline Storage Table (OST) and Personal Storage Table (.PST) files.
You cannot import OLM file directly into Outlook for Windows as it does not support the OLM file. OLM is an Outlook for Mac data file that stores local mailbox items such as emails, contacts, attachments, calendars, notes, journals, etc.
