Importing OLM files into Office 365 manually can be done through Outlook for Mac by first exporting the OLM data to a PST file. Then, you would need to configure your Office 365 account in Outlook for Windows and import the PST file. This process can be time-consuming and requires technical knowledge of both Mac and Windows versions of Outlook, making it less ideal for non-expert users to import OLM files to Office 365.
A simpler approach is using the MailConverterTools OLM Converter, which directly migrates OLM files to Office 365 without the need for complex steps. It ensures data integrity, preserves folder structure, and supports bulk migration, making the process faster and more efficient. The OLM Converter offers an easy solution for securely importing OLM files into Office 365 with minimal effort.
