Question details

Users opening an Excel attachment directly from Outlook for iPad find that their edits are not saved to Recents, Files, iCloud Drive, or OneDrive, even with AutoSave turned on.

Product: Excel for iPad / Outlook for iPad
Device & OS: iPadOS
Scenario: Editing an Excel spreadsheet received as an email attachment in the Outlook for iPad app.
Observed behavior: The file is stored in a temporary location, and edits are lost after closing because AutoSave fails to save it to a permanent location.

Before you start

Before closing the spreadsheet or making extensive edits, verify that the file has been saved to a designated cloud folder like OneDrive rather than a temporary mail cache.

Solution 1Recommended

Manually Save a Copy to OneDrive Before Editing

Manually uploading the file to a permanent cloud location ensures AutoSave functions correctly on your iPad.

Because attachments opened directly from Outlook are placed in a temporary folder by iPadOS, Excel's AutoSave feature cannot establish a permanent save path. You must manually define a storage location first.

Open the Attachment

Tap the Excel attachment in your Outlook for iPad email to launch it in the Excel app.

Access the Options Menu

Tap the three-dot menu icon located in the upper right corner of the Excel interface.

Save to OneDrive

Select 'Upload File' or 'Save a Copy', and choose OneDrive or iCloud Drive as the destination folder.

Edit the Cloud Copy

Begin editing the newly saved copy from your OneDrive folder. AutoSave will now work reliably.

App Limitation: This behavior is a known limitation or bug between the Outlook and Excel iPad apps regarding temporary file handling.

Frequently Asked Questions

Why did my edited Excel attachment disappear on my iPad?

When you open an attachment directly from Outlook, iPadOS stores it in a temporary cache. If you don't manually save a copy to a permanent location, Excel cannot AutoSave the changes, and the file is discarded when the app closes.

Can I recover an Excel attachment if I didn't save a copy?

Unfortunately, if the file was opened from Outlook and never manually saved to OneDrive, Files, or iCloud, the temporary edits are generally lost and cannot be recovered.

How do I ensure AutoSave works on iPad Excel?

AutoSave only works for files stored in supported cloud locations like OneDrive, SharePoint, or iCloud Drive. Always use 'Save a Copy' to move an attachment to one of these locations before making extensive edits.
