Customer Testimonials

See why IT administrators, businesses, and Microsoft 365 professionals trust the DRS Softech PST to Office 365 Migration Tool to securely import Outlook PST files into Microsoft 365 with speed, accuracy, and zero data loss.

Smooth PST Migration to Microsoft 365
"We needed to move Outlook PST files into Microsoft 365 mailboxes as part of our organization’s migration. The software made it easy to add multiple PST files, preview mailbox data, and select the required destination. The folder structure and email properties were preserved during the migration, making the overall process straightforward."
- James Anderson
(IT Administrator)
Useful Tool for Controlled PST Migration
"As an MSP, I'm usually the one explaining to a client why their migration is taking longer than promised, so anything that cuts down on manual cleanup earns its keep. Duplicate removal and date filtering helped us control which emails were migrated and avoid unnecessary duplicates. The Skip Existing Exports option came in handy too, since we could skip previously exported items. Not needing Outlook installed on the machine simplified things — one less thing to set up before we could actually get started."
- William Brown
(Managed Service Provider (MSP))
Simple and Flexible PST to Office 365 Migration
"I do this kind of work often enough that I've gotten picky about tools. What stood out here was how much control I actually had over what got moved — filtering by date range, skipping duplicates, picking specific folders instead of dragging the whole mailbox over. There's also an option to route everything into a custom folder on the other end, which came in handy for a client who wanted old mail kept separate. Previewing the PST contents before running anything meant no surprises halfway through."
- Robert Wilson
(IT Consultant)
Efficient Migration for Multiple User Mailboxes
"We were moving people over in batches as part of a reorg, not all at once, so having different migration modes to choose from mattered more than I expected. Mapping each PST to the right mailbox was straightforward. Before starting, I could look through the emails, contacts, calendar items, and attachments to make sure nothing was missing or mismatched — a few of our users had years of mail sitting in those files, so that check mattered."
