Answer in brief
A successful SharePoint cleanup starts with visibility, not deletion. Most storage issues stem from a combination of inactive sites, unnecessary versions, stale files, and unmanaged growth. A structured review process helps IT teams reclaim capacity while reducing governance risk and avoiding accidental data loss.
This checklist follows a practical sequence:
- Review inactive sites
- Identify large storage consumers
- Investigate version-heavy files
- Review inactive files
- Decide what to archive
- Remove unnecessary content
- Establish ongoing reporting
If your tenant is already approaching capacity limits, start with a storage assessment before purchasing additional storage.
Pre-cleanup safeguards
Before removing, archiving, or modifying content, IT teams should establish a review framework that protects business-critical information. Many organisations discover that a significant portion of storage can be reclaimed through governance improvements rather than immediate deletion. The goal is to identify waste while ensuring ownership, compliance, and recovery requirements remain intact.
Checklist:
- Identify site owners
- Review retention requirements
- Confirm recovery expectations
- Define archive criteria
- Establish approval workflows
- Document rollback procedures
✅ Review storage consumption
The fastest way to achieve meaningful cleanup results is to focus on the largest storage contributors first. Storage growth rarely occurs evenly across the tenant. Typically, a small number of sites, libraries, or file collections consume a disproportionate amount of SharePoint capacity and should be prioritised for review.
Checklist:
- Identify the largest SharePoint sites
- Review fastest-growing locations
- Locate oversized files
- Investigate duplicate content
- Prioritise high-impact cleanup opportunities

✅ Review version history
Version history plays an important role in recovery and collaboration but can become a significant source of storage consumption when left unmanaged. Rather than disabling versioning, organisations should evaluate whether historical versions continue to deliver business value and whether current retention settings remain appropriate.
Checklist:
- Review library version settings
- Identify version-heavy files
- Evaluate version retention policies
- Validate business recovery requirements
- Remove unnecessary historical versions where appropriate

✅ Review inactive sites
Inactive sites often represent completed projects, retired teams, or obsolete business areas. While some may require long-term retention, many can be archived or retired after an appropriate owner review. Site-level cleanup typically delivers greater storage savings than removing individual documents.
Checklist:
- Identify inactive sites
- Confirm site ownership
- Review access history
- Validate business relevance
- Archive or retire inactive locations
✅ Review inactive files
Many organisations retain years of documents that are rarely accessed but continue consuming valuable SharePoint capacity. Reviewing inactivity trends can reveal opportunities for archive, disposition, or further owner review while maintaining governance requirements and business continuity expectations.
Checklist:
- Locate inactive files and folders
- Group content by age and ownership
- Validate retention obligations
- Review archive suitability
- Remove unnecessary content after approval

✅ Decide whether to archive or delete
Archive and deletion serve different purposes and should not be treated as interchangeable actions. Content with ongoing compliance, business, or historical value may be suitable for archive, while content that no longer serves a purpose may be a candidate for deletion following an appropriate review process.
Archive content when
- Records may need future access
- Business teams request retention
- Recovery requirements exist
- Compliance obligations remain

Delete content when
- No business value remains
- Legal obligations have expired
- Owners approve removal
- Recovery requirements do not exist
✅ Establish an ongoing reporting cadence
The most successful SharePoint cleanups become operational processes rather than one-off projects. Regular reviews help prevent storage sprawl from returning and provide early visibility into sites, libraries, and content sets that require attention before capacity becomes a problem.
Recommended review schedule:
- Weekly storage growth review
- Monthly inactive-content review
- Monthly owner validation
- Quarterly archive assessment
- Quarterly governance review

Conclusion
A SharePoint cleanup initiative should focus on visibility, prioritisation, and governance before removal activities begin. By reviewing inactive sites, version-heavy files, dormant content, and archive opportunities in a repeatable sequence, IT teams can reduce storage consumption while maintaining user confidence and compliance requirements.
FAQ
What should I clean up first in SharePoint?
Most organisations should begin with inactive sites and high-storage locations before reviewing version-heavy files and inactive content. Starting with the largest opportunities usually delivers the fastest results.
Can I delete old SharePoint files to save storage?
Yes, but only after confirming ownership, retention requirements, and business value. Age alone is rarely a reliable basis for deletion decisions.
Does version history use SharePoint storage?
Yes. Historical versions consume storage and can become a major contributor to tenant growth if version settings are not reviewed periodically.
Is it better to archive or delete SharePoint content?
Archive is generally appropriate when future access may be required, while deletion is suitable when content no longer has business, operational, or compliance value.
How often should SharePoint cleanup be performed?
Storage visibility should be reviewed regularly, with most organisations benefiting from monthly review activities and quarterly governance assessments.
