Anyone any ideas on how I can migrate my email from the Mac (.olm) to Office 365?
Thanks
There is no as such manual method to convert you Mac OLM to Office 365. This can only be accomplished by using the third party tool which is an automated way to export the OLM file to Office 365.
Go with Stellar Converter for OLM which is an easy to use software even if you don’t have technical background. This utility is reliable and provides the instant solution when converting the large OLM files . It is one of the most trusted tool for its data integrity and data consistency .
Note: For this you have to go with the technician version of software but before this suggest you to try the free demo of software . Try before you buy
