Introduction
As data volumes grow rapidly, organizations face increasing challenges in managing information such as emails, documents, and business records. Studies suggest that nearly three-fourths of an organization’s intellectual property resides in its messaging systems, making mailbox storage space a critical factor.
In the past, storage was expensive, forcing organizations to either delete older data or rely on Outlook PST files for archiving. However, with rising concerns around data loss, vulnerability, and compliance, these methods are no longer sufficient. This is why email archiving and cloud-based solutions like Office 365 have become essential.
The Evolution of Email Archiving
Earlier, dedicated email archiving solutions provided separate repositories for storing emails. While these improved performance, they still posed security risks and required offline storage.
Today, organizations increasingly prefer cloud storage, which offers better scalability, affordability, and security. This shift has made migrating archives to Office 365 a priority for IT teams.
Why migrate archives to Office 365?
Office 365 offers a secure, centralized, and scalable platform to manage both live and archived data. Migration not only simplifies storage management but also strengthens compliance, improves accessibility, and supports business continuity.
Key challenges in archive migration
Despite its benefits, migrating archives to Office 365 presents unique challenges:
- Inactive shortcuts: Some archive solutions use shortcuts to access archived data, which break after migration since Office 365 does not recognize them.
- PST vulnerabilities: While PST files provide offline storage, they are prone to corruption, loss, and security breaches.
- Public folder limitations: Though public folders store critical business data, they face restrictions on size and scalability.
- Mailbox management: After migration, it can be difficult to differentiate between primary and archive mailboxes in Office 365.
Best practices for archive migration to Office 365
1. Migrate archive and live mailboxes together
Performing a combined migration ensures that shortcuts remain intact and data integrity is maintained.
2. Move PST files securely
Since PST files are highly vulnerable, migrating them to Office 365 is the safest approach. Tools like EdbMails PST to Office 365 Migration streamline this process with minimal risk.
3. Address public folders smartly
While public folders can store vast amounts of data, they have limitations. Consider Office 365 Groups as an alternative for collaboration and resource sharing, offering similar features with more flexibility.
4. Optimize data before migration
Eliminate redundant or unnecessary data before migrating. This reduces storage costs, shortens migration time, and ensures only business-critical information is transferred.
5. Plan for storage management
Storage in Office 365 depends on your subscription plan. For instance, E3 plans offer unlimited archive storage, while others have limits. Assess your plan and align it with your long-term data needs.
