The safest way to reduce Dynamics 365 storage without deleting records is to move attachments and files out of Dataverse while keeping them securely linked and fully accessible inside Dynamics 365.
At this stage, most organizations already understand what is driving storage growth. The real question becomes how to reduce costs without introducing risk, disrupting users, or compromising compliance.
Not all storage reduction approaches are equal—and some create more problems than they solve.
Why many storage “fixes” create new risks
When storage overages surface, teams often reach for the fastest option available.
Common responses include:
- Deleting historical attachments
- Disabling email tracking
- Manually archiving data
- Purchasing additional Dataverse capacity
While these approaches may reduce pressure temporarily, they introduce tradeoffs that are often unacceptable for IT teams.
Deleting data risks compliance and audit readiness. Restricting features frustrates users. Buying more storage treats the symptom, not the cause.
For Solution Architects, these approaches are difficult to standardize. For IT Managers, they create long-term uncertainty.
What happens when teams try manual cleanup first
Organizations often attempt manual cleanup before considering structural options.
For example, an IT team identifies large attachment tables and asks business users to remove “old files.” Weeks are spent debating what can be deleted. Progress is slow, and risk remains high.
Even when some files are removed, the problem usually returns—because the underlying behavior hasn’t changed.
When storage reduction relies on deletion or behavior change, the cycle tends to repeat. Historical data is removed only to be needed later. Users work around restrictions by storing files elsewhere. IT teams end up managing exceptions instead of solving the root cause.
Over time, storage cost control becomes reactive rather than planned, and each new storage incident is more disruptive than the last.
What makes a storage reduction approach “safe”
From a technical and operational standpoint, a safe storage reduction approach has four characteristics:
- No data loss
- No user retraining
- No broken links or workflows
- No architectural redesign
Safe approaches focus on how files are stored, not on limiting who can use the system or what data must be removed.
This is the difference between cleanup and control.
Externalizing attachments without breaking Dynamics 365
Externalizing attachments means files are stored outside of Dataverse while remaining visible and accessible from Dynamics 365 records.
Users still open attachments from timelines, emails, and activities. Permissions are respected. Record relationships remain intact.
The change happens at the storage layer—not the user layer—which is why this approach scales across teams and environments.
Product as the resolution
This is why organizations and partners use AttachmentExtractor from mscrm-addons.com.
AttachmentExtractor externalizes attachments from Dataverse while preserving native access inside Dynamics 365. Files are moved to secure external storage, while lightweight references remain in the system so users experience no disruption.
For IT Managers, this provides a safe way to reduce storage costs without deleting records. For Solution Architects, it offers a repeatable, low-risk approach that can be applied consistently across environments.
Frequently Asked Questions
No. When done correctly, attachments remain accessible from Dynamics 365 and continue to follow existing permissions and relationships. Users can still open files from timelines, activities, and records without changing how they work.

No. Users continue opening and interacting with attachments the same way they do today.
Yes. Safe approaches address both existing storage and future growth.
