Anyone any ideas on how I can migrate my email from the Mac (.olm) to Office 365?
Thanks
Hii,
you can try OLM to PST converter software. its easy to use and one click download . you can also try the free demo version of this software which helps you to convert your all OLM data in PST format. IF you are satisfied then you can go for paid version .
