Anyone any ideas on how I can migrate my email from the Mac (.olm) to Office 365?
Thanks
Grab OLM Migrator software which will enable users to export OLM Files to Office 365 account. It provides users a direct option to upload OLM to Office 365 account by entering Office 365 Username & Password account.
