You may see Outlook error 0x80040610 when sending an email. The error states the sent message could not be saved. This prevents a copy from being stored in your Sent Items folder. The problem is usually caused by a corrupted Outlook data file or a full storage location. This article explains the root cause and provides steps to resolve the error.
Key Takeaways: Fixing Error 0x80040610
- File > Account Settings > Data Files > Repair: Uses the Inbox Repair Tool to fix corruption in your primary Outlook Data File.
- File > Options > Mail > Save messages > Empty Sent Items folder: Temporarily disables saving sent items to bypass the error and free up space.
- Windows Search: Indexing Options > Advanced > Rebuild: Rebuilds the Windows Search index if corruption is preventing Outlook from saving items.
Why Outlook Error 0x80040610 Occurs
Error 0x80040610 appears because Outlook cannot write a copy of the sent email to its designated storage location. The most common technical cause is a corrupted Outlook Data File, specifically the PST or OST file where your mailbox data is stored. When a sector in this file is damaged, Outlook fails to save new items like sent messages.
Another frequent cause is a full or restricted storage location. If the disk drive containing your Outlook data file has no free space, the save operation fails. Similarly, if the Sent Items folder itself has reached a size limit set by your administrator or the file system, the error will trigger. Incorrect folder permissions or a corrupted Windows Search index can also interfere with the save process.
How OST and PST Files Become Corrupted
OST files used with Microsoft 365 or Exchange accounts can corrupt during network interruptions or sudden Outlook closures. PST files, often used for POP/IMAP accounts or archives, can corrupt if they approach their maximum size limit, typically 50 GB for the Unicode format. Large file attachments and frequent item deletions can also fragment these data files over time, increasing corruption risk.
Steps to Resolve Error 0x80040610
Follow these steps in order. Start with the simplest fix related to storage space before moving to data file repairs.
- Check Available Disk Space
Open File Explorer and navigate to the drive where your Outlook data file is stored. Right-click the drive, select Properties, and ensure there is at least 1 GB of free space. If space is low, delete unnecessary files or move them to another drive. - Disable Saving Sent Items Temporarily
In Outlook, go to File > Options > Mail. Scroll to the Save messages section. Uncheck the box for Save copies of messages in the Sent Items folder. Click OK. This bypasses the error so you can send emails immediately. Re-enable the setting after completing the other fixes. - Run the Inbox Repair Tool
Close Outlook. Press the Windows key, type “scanpst.exe”, and press Enter to run the tool. Click Browse to locate your Outlook Data File, usually in C:\Users\[YourName]\AppData\Local\Microsoft\Outlook. Click Start to begin the scan. If errors are found, click Repair. After repair, open Outlook to test sending an email. - Create a New Outlook Profile
A corrupted profile can cause save errors. Go to Windows Control Panel > Mail > Show Profiles. Click Add, enter a name for the new profile, and re-add your email account. Set this new profile as the default. Restart Outlook and use the new profile to see if the error is resolved.
If Outlook Still Has Issues After the Main Fix
Error Persists After Running ScanPST
If the Inbox Repair Tool fails or the error returns, your data file may be severely damaged. Create a new PST file and move your existing items. In Outlook, go to File > New Items > More Items > Outlook Data File. Name it and click OK. Drag your old folders from the corrupted file into the new one. Set the new file as your default delivery location in File > Account Settings > Data Files.
Sent Items Folder is Missing or Corrupt
Sometimes the specific Sent Items folder is damaged. Right-click your Sent Items folder and select Properties. Go to the General tab and note the folder path. Try moving the folder: create a new folder named “Sent Items New”, drag emails from the old folder into it, and delete the original corrupted folder. You cannot rename the default Sent Items folder, but you can set the new folder as the default save location in File > Options > Mail.
Error Occurs Only with Specific Recipients or Large Attachments
This pattern suggests a problem with the specific email item, not the data file. Try sending the email without attachments first. If it sends, compress the attachments or use a cloud sharing link. Also, check if the recipient’s address is valid. An invalid address can sometimes cause a save failure in the background.

You can now resolve the sent message save error in Outlook. Use the Inbox Repair Tool to fix the most common cause of data file corruption. For a quick workaround, disable the save sent items option temporarily. As an advanced tip, schedule a monthly task to run the SCANPST tool on your primary Outlook data file to prevent future corruption.
