Logged into Office 365 Online. Opened Excel and a months recent history has vanished. HELP

Question

As the title says. I logged back in after a few days and opened excel from the apps button down the left hand side. Usually recent work is shown but this time it's all gone. Nothing going back to February is showing. I need to find the recent work from March that I have been working on for months. Why has it suddenly gone? As far as I know there is no delete option so that's not a plausible explanation. What am I missing?

Hello @Darran

In this case, after logging into Office 365 Online and opening Excel via the app launcher, you noticed that their “Recent files” history is empty. Files they had been working on throughout March (and earlier) no longer appear in Excel’s recent list.

I would like to clarify that the “Recent” list in Excel Online is not a storage location, but only a temporary history of files opened recently within a specific session, browser, or access method. If this list appears empty, it does not mean that your files have been deleted.

This situation can occur for several common reasons, including:

• Signing in from a different browser or device
• Clearing browser cache or cookies
• Opening Excel from a different entry point (for example, the app launcher instead of OneDrive)
• Using a different Microsoft account (personal vs. work/school)
• Previously opening files from email links, Teams, or SharePoint

To locate the files you worked on in March, please follow these steps:

• Go to your OneDrive
• Select My files
• Use the search bar to look for the file name or a related keyword
• Sort the files by Modified date (Newest first) to quickly find recently edited documents

If the files were shared with you or belong to a team:

• Check the Shared section in OneDrive
• Review the relevant Microsoft Teams channel or SharePoint document library

Please note that Office 365 does not automatically delete files when the Recent list is cleared. Your files should still be available in OneDrive, SharePoint, or Teams unless they were manually removed.

To avoid this issue in the future, we recommend:

• Pinning important files in Excel or OneDrive
• Opening and saving files directly from OneDrive folders rather than from email links

If you are still unable to locate your files after completing these steps, please come back and I will try to assist you further.

Answer 2

The most likely cause is that Excel Online is no longer seeing the same set of files associated with the signed‑in account or storage location, rather than that the files were deleted.

Key points based on how Office recent lists work:

1. The “Recent” list is just a shortcut list
   • The list shown when Excel opens is a history of files the account has opened recently; it does not store the files themselves.
   • If the account changes, or the device sync state changes, the list can appear to “lose” items even though the files still exist.
2. Recent lists sync with the Microsoft account
   • The list of recently used files synchronizes with the Microsoft account across devices.
   • If signed in with a different account than usual (for example, a work vs. personal Microsoft account), the recent list will reflect only files opened under that account.
   • If someone else used the same device while signed in as this account, their files could appear in the list, and the expected ones may seem to be missing.
3. What to check and try
   1. Confirm the signed‑in account in Excel Online (top‑right profile) is the same one used when the March files were created/edited.
   2. Open OneDrive or SharePoint directly (where the files are stored) and browse/search for the workbook names or keywords instead of relying on the Recent list.
   3. If the files are found but an older version opens, use Version History to restore the needed version:
      • In OneDrive/SharePoint, right‑click the Excel file.
      • Select Version history.
      • Choose the appropriate earlier version and select Restore. Note that restoring replaces the current version with the selected one and any later updates are lost.

If the files themselves are still present in OneDrive/SharePoint, they can be opened even if they no longer appear in the Recent list. The Recent list itself cannot be “recovered”; it repopulates as files are opened again.
