Why convert MSG to PST?
PST is the archive format used to back up, move between machines, or share an Outlook mailbox. If you have .msg files scattered on disk and want them in one organised archive, collecting them into a PST is the standard approach.
How to convert MSG to PST
Microsoft Outlook APP
Open Outlook with a PST data file loaded, then drag one or more .msg files from File Explorer into any PST folder; Outlook writes the messages into the PST immediately.
Aid4Mail APP
Point Aid4Mail at the folder containing your .msg files, set the output to PST, and run the import; suitable for large batches of dozens to thousands of messages.
