OneDrive Archiving in 2026: The Options (and the Gaps)

OneDrive Archiving: Start With the Awkward Truth

There is no native Microsoft "archive tier" for OneDrive. If you came here expecting the OneDrive equivalent of Microsoft 365 Archive - a button that moves inactive OneDrive files to cheaper cold storage - it does not exist. Microsoft's own documentation is explicit: Microsoft 365 Archive is "for inactive SharePoint files and sites," and its file-level archive is "available only for SharePoint sites."

That leaves OneDrive archiving as a genuinely different problem from SharePoint archiving, and one where the right answer depends entirely on why you're archiving:

• Active users whose OneDrive is growing - there's no native archive tier, and the practical levers are storage governance, quota management, and retention policy rather than a true archive.
• Departed employees whose OneDrive must be preserved - this is where archiving genuinely applies, and where an automated tool earns its place.
• Unlicensed OneDrive accounts - Microsoft has its own automatic archiving behaviour here, which is a compliance risk more than a solution.

This guide covers all three honestly, including where the tooling runs out.

Why Microsoft 365 Archive Doesn't Cover OneDrive

Microsoft 365 Archive is Microsoft's cold-storage tier for inactive content. It archives entire SharePoint sites (generally available) and, in preview, individual SharePoint files. Archived content drops to a lower storage rate and is excluded from the active tenant storage quota.

Per Microsoft's Microsoft 365 Archive documentation, the coverage boundary is clear:

• Microsoft 365 Archive "provides cost-effective storage for inactive SharePoint files and sites."
• File-level archive "is available only for SharePoint sites."
• OneDrive appears in the documentation only as a limitation - if an archived SharePoint file is moved or copied into OneDrive, Microsoft notes its archived state "might not always be visually represented in the OneDrive user interface."

In other words, OneDrive is not a workload Microsoft 365 Archive operates on. There is no OneDrive site archive, and no OneDrive file archive. For a full breakdown of what Microsoft 365 Archive does cover, see SharePoint archive site explained and Squirrel vs Microsoft 365 Archive.

Archiving an Active User's OneDrive: The Honest Answer

For a current employee whose OneDrive is filling up, "archiving" is the wrong mental model - there's no cold tier to move the files to. What you actually have are governance levers:

• Retention policies (Microsoft Purview). A retention policy can preserve OneDrive content for a defined period, but it preserves data - it does not move it to cheaper storage or reduce consumption. In fact, retained-and-deleted content lands in the OneDrive Preservation Hold Library, which increases storage use.
• Quota management. The OneDrive storage quota per user is set by licence and adjustable by admins within limits. Managing quotas is about controlling growth, not archiving. Note the 2026 change to over-quota enforcement in OneDrive quota enforcement (MC1310684) - Microsoft now places over-quota OneDrive users into read-only state.
• Move-to-SharePoint patterns. Some organisations move shared or team content out of individual OneDrives into SharePoint document libraries, where it can then be archived with a file-level SharePoint archiver. This works for content that shouldn't have been in personal OneDrive in the first place, but it's a migration, not a OneDrive archive.

The honest bottom line: for active-user OneDrive, there is no clean archive-to-cheaper-storage option in 2026 - native or third-party. If a vendor claims to "archive active OneDrive to cut storage cost," ask exactly how, because the platform doesn't expose the stub-and-rehydrate mechanism for OneDrive that makes SharePoint file archiving work.

Archiving a Departed Employee's OneDrive: Where It Actually Applies

The scenario where OneDrive archiving genuinely matters is offboarding. When an employee leaves, their OneDrive holds files the business may need later - and Microsoft's deletion clock is unforgiving.

Per Microsoft's documentation on removing a former employee, once a departed user's account is deleted, their OneDrive content is retained for 30 days by default before permanent deletion. That default is configurable in the SharePoint admin center (any value from 30 to 3650 days), but most tenants leave it at 30. Simply disabling the account doesn't start the clock - deletion does - but organisations routinely delete accounts to reclaim licences, which starts the 30-day countdown.

Three ways organisations handle departed-user OneDrive preservation:

• Keep the licence active. Preserves the OneDrive indefinitely, but costs a full Microsoft 365 licence per departed user, forever. For an enterprise with steady turnover this quietly accumulates into serious annual spend.
• Apply a Purview retention policy or hold before deletion. Preserves the content for compliance, but adds Purview complexity, doesn't necessarily let you reclaim the licence, and leaves the data in a form that's not easily browsable by HR or managers.
• Archive the OneDrive to your own storage, then delete the account. Capture the OneDrive content (along with the mailbox and Teams data) into storage you own, reclaim the licence, and delete the account cleanly.

That third pattern is what Chipmunk automates. The moment a user account is disabled in Microsoft Entra ID, Chipmunk detects the departure and archives the user's OneDrive, Exchange Online, and Teams data into your own Azure Blob Storage account - no manual export, no scripts. When the archive completes, IT gets a confirmation and can reclaim the licence immediately, knowing the data is preserved and searchable. The full workflow is in the Microsoft 365 departed user archiving guide, and the offboarding sequence in the Microsoft 365 offboarding checklist.

The Unlicensed OneDrive Archiving Trap

There's a third OneDrive-archiving scenario, and it's one Microsoft imposes rather than one you choose. As covered in the 2025 OneDrive licensing changes, Microsoft introduced automatic archiving of unlicensed OneDrive accounts - accounts left without an assigned licence get archived by Microsoft and become inaccessible unless covered by a retention policy or legal hold.

This matters for offboarding because a common cost-saving tactic - removing a departed user's licence but leaving the account in place to "keep the data" - can trigger Microsoft's own archiving of that unlicensed OneDrive. The data isn't necessarily lost, but it's no longer readily accessible, and recovering it may require re-licensing. The clean pattern remains: preserve the data to storage you control before you strip the licence, then delete the account.

OneDrive Archiving Options Compared

Scenario	Native Microsoft option	Practical answer
Active user's OneDrive growing	None (Microsoft 365 Archive excludes OneDrive)	Quota management + retention governance; no true archive tier exists
Departed employee's OneDrive	Keep licence, or Purview hold before deletion	Automated archive to your own Azure storage (Chipmunk), then reclaim the licence
Unlicensed OneDrive account	Microsoft auto-archives it	Preserve to your own storage before removing the licence
Shared/team content in personal OneDrive	Move to SharePoint	Migrate to a SharePoint library, then archive at the SharePoint level

Frequently Asked Questions

Can you archive OneDrive with Microsoft 365 Archive?

No. Microsoft 365 Archive is documented as covering inactive SharePoint files and sites only. Its file-level archive is "available only for SharePoint sites." OneDrive is not a supported workload - there is no OneDrive site archive or OneDrive file archive in Microsoft 365 Archive.

How do you archive a departed employee's OneDrive?

Either keep their licence active (costly and indefinite), apply a Microsoft Purview retention policy or hold before deleting the account, or archive the OneDrive content to storage you own and then delete the account. The automated version of the third option - capturing OneDrive, mailbox, and Teams data on account disable - is what Chipmunk does.

How long is a deleted user's OneDrive kept?

By default, 30 days after the account is deleted, then permanently deleted. This is configurable in the SharePoint admin center to any value from 30 to 3650 days. Note that disabling an account does not start the timer - only deleting the account does.

Is there a way to move inactive OneDrive files to cheaper storage?

Not natively, and not cleanly with third-party tools either. The stub-and-rehydrate mechanism that makes SharePoint file archiving work isn't exposed for OneDrive. For active-user OneDrive, the levers are quota and retention governance, not archiving. Content that genuinely belongs in shared storage can be moved to SharePoint and archived there instead.

Does removing a OneDrive licence delete the data?

Removing the licence alone doesn't immediately delete the data while the account exists, but it can trigger Microsoft's automatic archiving of the now-unlicensed OneDrive, making it inaccessible. Deleting the account starts the 30-day deletion clock. Preserve the data before doing either.
