Many users want to create a backup of their Office 365 emails in a PDF format to keep the data secure. However, there are no direct methods available to perform the conversion. Thus, I would recommend using the MacSonik Office 365 backup tool for Mac to create a backup of multiple Office 365 emails risk-free. This advanced utility maintains the original folder hierarchy and allows bulk conversion of Office 365 emails. The Office 365 backup also enables converting/migrating Office 365 emails to 20+ file formats and email clients with high data accuracy. Its user-friendly interface makes it convenient to use by both technical and non-technical users.
