The MSP Migration Dilemma
Managed service providers handle dozens of email migrations every year. Whether moving clients from on-premises Exchange to Microsoft 365 or consolidating multiple platforms into Google Workspace, the migration itself is just the beginning. The real headache starts the morning after, when the client's entire staff opens their mailbox and discovers that every email shows the same date.
This isn't an edge case. It's one of the most predictable outcomes of IMAP-based email migration. Tools like BitTitan MigrationWiz, CloudM Migrate, and imapsync all produce the same result: the destination server stamps a new "Received" header on every message with the migration timestamp, and email clients display that date instead of the original.
What MSP Clients Actually Complain About
End-User Frustration
The typical complaint from end users is simple: "All my emails show the same date." Users who relied on date-based sorting can no longer navigate their inbox. Executive assistants lose their workflow. Sales teams can't locate proposals by date. The complaints arrive within hours of migration completion.
Management Escalation
When enough staff members complain, the issue escalates. The CTO contacts the MSP with a blunt question: "Why did the migration break our email dates?" This puts the MSP in a difficult position. The migration was technically successful, but the client perceives it as a failure because the visible result is a broken inbox. How do you explain that the IMAP protocol itself caused the problem?
Compliance and Legal Concerns
For clients in regulated industries, wrong email dates create compliance exposure. eDiscovery tools return inaccurate results. Audit trails become unreliable. MSPs serving these clients can't dismiss date issues as cosmetic.
How MSPs Currently Handle Date Issues
Ignoring the Problem
The most common approach is to tell clients that "sorting by sent date" is the workaround. This avoids immediate cost but damages the client relationship. As explained in why sorting by sent date is not a real fix, this workaround fails for search, compliance, email rules, and every device where the setting hasn't been manually changed.
Custom Scripting
Some technically advanced MSPs write custom scripts to attempt date correction. This takes 10 to 20 hours of development, 2 to 4 hours per mailbox to run, has no built-in verification, and costs 300 to 600 EUR per mailbox at typical billing rates. And the risk? A script that handles simple plain-text emails but silently corrupts messages with S/MIME signatures, nested MIME boundaries, or non-ASCII encoded headers. How do you verify that every single corrected email across 50 mailboxes is intact?
Hiring a Specialist
Subcontracting to a consultant costs 300 to 1,200 EUR per mailbox and introduces scheduling delays. For a 50-mailbox project, this adds 15,000 to 60,000 EUR.
How Redate.io Solves This for MSPs
Batch Processing at Scale
Redate.io handles multiple mailboxes in a single project. Connect the client's email platform, select mailboxes, and run the free scan across all of them simultaneously. After reviewing results, start the correction with a single action. Redate.io's proprietary correction engine processes all mailboxes with pattern matching across hundreds of known migration tool signatures and runs integrity verification on every corrected email.
Volume Discounts for MSPs
Redate.io offers volume pricing for MSPs:
- 5 or more mailboxes: 15% discount
- 10 or more mailboxes: 25% discount
- 20 or more mailboxes: 35% discount
For 25 mailboxes averaging 5,000 emails each (99 EUR per mailbox at standard pricing), the 35% volume discount brings the per-mailbox cost to approximately 64 EUR. Total project cost: 1,600 EUR, a fraction of what custom scripting or a consultant would charge.
The Redate.io Partner Program
MSPs who regularly perform migrations can join the Redate.io Partner Program for priority support, dedicated onboarding, and volume pricing on every project. The partner program is designed for MSPs who want to offer date correction as a standard part of their migration service.
Step-by-Step: Fixing Client Mailboxes as an MSP
Step 1 - Connect the Client Platform
Log into Redate.io and add a new project. For Google Workspace: enter Service Account credentials with domain-wide delegation. For Microsoft 365: register an Azure AD app with mail permissions. For other IMAP servers: enter server address and admin credentials. Connection takes less than two minutes.
Step 2 - Select Mailboxes and Run the Free Scan
Select which mailboxes to scan. Redate.io scans each mailbox to identify emails with migration headers. The scan is free and non-destructive. Results show affected email count per mailbox and the corresponding pricing tier.
Step 3 - Review and Start the Fix
Review scan results and confirm which mailboxes to fix. Volume discounts apply automatically. After payment, Redate.io's multi-stage analysis pipeline processes every selected mailbox. The correction engine handles encoding edge cases, multipart message structures, digital signatures, and dozens of other scenarios that would cause a basic script to corrupt data. Every email goes through integrity verification, and originals are moved to a backup folder.
Step 4 - Confirm with the Client
Ask users to restart their email client or wait for the next sync. The MSP receives a processing report for each mailbox showing emails corrected, any skipped (such as S/MIME signed messages), and verification status.
Why Date Correction Should Be Part of Every Migration Proposal
MSPs who include date correction in their migration proposals avoid the post-migration support burden entirely. This positions the MSP as thorough, reduces support tickets to near zero, and turns a common failure point into a differentiator. At 64 EUR per mailbox with volume discount, the cost is negligble compared to lost client trust and unpaid support hours.
