How do I export IMAP emails into PST and move calendar data to Office 365?

I had an urgent requirement to export my IMAP emails into PST format for Outlook access and also transfer calendar information to Microsoft 365. After researching several options, I used the CloudXena IMAP Email Backup Tool and found it very reliable.
The software supports exporting IMAP emails into many formats, including PST, PDF, MSG, MBOX, DOC, DOCX, and CSV. The conversion process was quick, and all mailbox folders remained organized after completion. It also provides an attachment management feature that lets users save attachments separately for easy access.
Another helpful feature is the selective timeframe filter, which allowed me to migrate emails only from a specific date range. This saved both time and storage space. The duplicate remover option also prevented repeated emails from being backed up.
What impressed me most was the ability to migrate IMAP Calendar to Office 365 along with email data in a single workflow. The migration completed without any missing items or formatting issues. Since the interface is straightforward, even users without technical experience can operate it comfortably. I would definitely recommend this solution for secure email backup and migration purposes.
