Deleted a file from OneDrive or emptied an Outlook folder by accident? Microsoft 365 keeps most deleted content recoverable for 93 days in OneDrive and SharePoint, and 14 days by default in Exchange Online mailboxes — after that window closes, recovery depends on whether an admin set up a retention policy or litigation hold before the deletion happened.
- OneDrive and SharePoint keep deleted files recoverable for 93 days across two recycle bin stages.
- Outlook and Exchange Online keep purged emails recoverable for 14 days by default, extendable to 30.
- A deleted user account and its OneDrive can be restored by an admin within 30 days of deletion.
- Past these windows, only a retention policy or litigation hold set up in advance can save the data.
- Restore deleted files microsoft 365 tasks take under five minutes when the item is still inside the retention window.
Why this matters
A missed retention window is permanent data loss — there is no support ticket or paid recovery service that reverses it once Microsoft 365 has purged an item past its retention period. Businesses running finance, invoicing, or client records through Microsoft 365 (mailboxes, OneDrive, SharePoint document libraries) need to know these windows before an accident happens, not after. If your business handles this on ad-hoc requests to IT, you're one 95-day-old deletion away from something unrecoverable.
A good first move if you're setting up mailboxes and files for a growing team is to review the process for migrating business email and files to Microsoft 365 properly from day one — a clean migration reduces the accidental-deletion incidents that trigger these recovery scenarios in the first place.
How to restore deleted files and emails in Microsoft 365
The steps differ depending on what got deleted and how long ago. Here's the fastest path for each case:
Restoring a file from OneDrive or SharePoint:
- Open OneDrive or the SharePoint site in a browser.
- Click Recycle bin in the left navigation.
- Select the file or folder, click Restore.
- If it's not there, check the second-stage recycle bin (site owners and admins only) — items move here after being deleted from the first bin.
Restoring an email in Outlook:
- Check the Deleted Items folder first — items sit here indefinitely until manually emptied.
- If emptied, go to Deleted Items > Recover Items Recently Removed From This Folder.
- Select the email, click Restore.
- If it's gone from that view too, an Exchange admin needs to check compliance search or a retention hold.
| Scenario | Where to look first | Default recovery window |
|---|---|---|
| Deleted OneDrive file | OneDrive Recycle bin | 93 days |
| Deleted SharePoint file | Site Recycle bin (two stages) | 93 days total |
| Deleted email (not emptied) | Outlook Deleted Items | Indefinite until emptied |
| Emptied/purged email | Recover Items Recently Removed | 14 days (up to 30) |
| Deleted user account | Microsoft 365 admin center | 30 days |
OneDrive and SharePoint: 93 days to restore deleted files
Deleted files move to a first-stage recycle bin, and if deleted again, to a second-stage bin — but the total recovery window from the original deletion is 93 days. Past that, the file is gone unless a retention policy captured a copy separately. If your business stores client contracts or financial records in SharePoint, pairing this with a SharePoint storage expansion and a retention policy is the combination that actually protects data long-term, not just the recycle bin.
Outlook and Exchange Online: 14 days by default, extendable to 30
Once an email is emptied from Deleted Items, it sits in a hidden Recoverable Items > Deletions folder for 14 days by default. Global admins can extend this to a maximum of 30 days through the Exchange admin center, and a litigation hold removes the time limit entirely for as long as the hold is active. Businesses on a best Microsoft 365 plan for small businesses setup rarely have holds configured by default — it's an extra step, not something that ships turned on.
Deleted user accounts: 30 days to restore the whole mailbox and OneDrive
When an employee leaves and their Microsoft 365 account gets deleted, the account itself — along with its mailbox and OneDrive — stays recoverable for 30 days from the admin center. After that, everything tied to the account, including files nobody thought to back up elsewhere, is unrecoverable. This is the scenario that catches businesses off guard most often: someone offboards a staff member, waits past day 30, then realizes a shared project file only existed in that person's OneDrive.
Why recovery windows vary
- Deletion type — a normal delete, an emptied folder, and a hard-purge each start a different countdown.
- Retention policies — an admin-configured policy can extend or override the default windows entirely.
- Litigation hold — removes the time limit on Exchange Online recovery for as long as it's active.
- License tier — some retention and hold features require Business Premium or higher, not Business Basic.
- Account status — a deleted user account has its own 30-day clock, separate from file-level recycle bins.
- Manual backup habits — a separate backup routine is the only thing that protects data past every built-in window.
“The recycle bin is not a backup — it's a 93-day grace period, and after that the data is gone for good.”
Businesses that can't risk the 93-day or 14-day cutoffs typically layer a dedicated cloud backup software for business file protection on top of the native Microsoft 365 recovery tools, which keeps versioned copies independent of any retention policy setting.

Related questions
How long do deleted OneDrive files stay recoverable?
Deleted OneDrive files stay recoverable for 93 days total, split across a first-stage and second-stage recycle bin. Past 93 days, the file is permanently gone unless a retention policy captured a separate copy.
Can you recover a permanently deleted email in Microsoft 365?
A permanently deleted email is recoverable only if a litigation hold or retention policy was active before the deletion happened. Without one, once the 14-day (or extended 30-day) Recoverable Items window closes, the email cannot be restored by anyone, including Microsoft support.
What happens when a Microsoft 365 user account is deleted by mistake?
A mistakenly deleted account can be restored within 30 days from the Microsoft 365 admin center, bringing back the mailbox, OneDrive, and licenses as they were. After 30 days, the account and its data are permanently removed and cannot be recovered.
FAQ
How do I restore deleted files in Microsoft 365?
Open OneDrive or SharePoint, go to the Recycle bin, select the file, and click Restore — files stay recoverable there for 93 days after deletion. Past that window, only a retention policy set up beforehand can bring the file back.
How long does Microsoft 365 keep deleted emails?
Microsoft 365 keeps deleted emails in the hidden Recoverable Items folder for 14 days by default after Deleted Items is emptied, extendable to 30 days by an admin. A litigation hold removes the time limit entirely while it's active.
Can I recover a file after 93 days in OneDrive?
No, a file deleted more than 93 days ago in OneDrive is permanently gone unless a retention policy or separate backup captured a copy before the window closed. The 93-day count includes both the first-stage and second-stage recycle bin.
Is Microsoft 365 backup the same as the recycle bin?
No, the recycle bin is a temporary grace period, not a backup — it expires automatically at 93 days for files and 14 to 30 days for emails. A dedicated backup solution keeps versioned copies independent of these built-in retention limits.
Who can restore a deleted user's mailbox in Microsoft 365?
Only a Microsoft 365 global admin can restore a deleted user's mailbox, and only within 30 days of the deletion through the admin center. After 30 days the mailbox and its contents are permanently removed.
Does Microsoft 365 Business Basic include the same recovery windows as Business Premium?
The default 93-day and 14-day recovery windows apply across Microsoft 365 tiers, but some advanced retention and hold features are limited to higher plans. Checking plan details before relying on extended retention avoids a surprise gap in coverage.
What is the second-stage recycle bin in SharePoint?
The second-stage recycle bin holds files deleted from the first-stage bin and is only visible to site owners and admins, not regular users. It retains the file for whatever remains of the original 93-day window, not a fresh 93 days.
One last thing
Most data-loss incidents in 2026 happen because nobody flagged the 93-day or 14-day countdown until it had already expired — the recovery tools work fine, the gap is always in timing, not technology. Setting a retention policy once takes fifteen minutes and closes that gap for every future deletion, planned or accidental.
