Our office recently required me to export Outlook Calendar to ICS so the scheduling information could be imported into another collaborative calendar system used by the team. The native Outlook export option is straightforward but only handles one calendar at a time, and repeating the process for multiple department PST archives increases the chance of missing some event data. I was particularly concerned about preserving recurring event patterns, attached notes, and timezone adjustments because those details are important for project timelines. Since the manual method does not provide batch processing or strong filtering controls, I explored automated solutions that could simplify the migration and reduce manual checking. Eventually, I evaluated the SysInfo PST Converter and noticed it supports bulk PST loading, selective folder export, and maintains complete calendar metadata during conversion. It also includes preview functionality before saving, so you can confirm the extracted events. This made the whole export workflow far more organised compared to repeated manual steps.
