The receipts — real demand
“Hi all, Is there a way to export all emails into separate .msg files so whenever I need one I can have a look without loading the .pst and waiting for indexing to happen. It would be used ad hoc, so I do not want to load the .pst into outlook permanently. I have tried few things, googled a bit and the only solution seems to be just manually drag them all from folders to explorer.”

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
Office workers and IT professionals managing large PST archives who need ad-hoc email access without the indexing overhead of opening PST files in Outlook. No search volume, but the pain is operational and specific to enterprise/retained-archive workflows.
Competition & the opening
Outlook, PST recovery tools (EML exporters), and email archiving platforms (Veritas, Commvault) all touch this. The gap: none offer a fast, on-demand bulk export to individual .msg files that bypasses Outlook's indexing entirely.
What's hard to build
PST files are proprietary and require parsing (libpst, osmsg libraries exist but are fragile). Building reliable, fast extraction at scale without corrupting metadata is non-trivial. Feasibility is 8/10 (hard), confirming the file-format work and performance tuning are genuine blockers.
Why now
PST/mailbox archives are increasingly large and Outlook indexing has become a bottleneck as email volumes grow; on-demand extraction without full load is now a clear workflow need.
