Fix: ‘Outlook Error 0x80040610’ issue

Modify Outlook Account Settings

1. Open Outlook and go to File > Account Settings from the menu.
2. Click on the Email tab and double-click on your email account to change or look at its settings.
3. Check to see if you put the right names for the Incoming and Outgoing Servers in the right boxes.
4. Now, click More Settings and put a check mark in the box in the Outgoing Server tab that matches what you want to do.
5. Go to the Outgoing Server tab and make sure the box next to My outgoing server (SMTP) requires authentication is checked.
6. When you’re done, click OK, restart Outlook, and check to see if the error is gone.

Repair Outlook Data File

The Outlook data file, which is also called a PST file, has all the information you have in Outlook, like your emails, contacts, calendar entries, and other similar information. If this file gets damaged, it can cause a number of problems, such as the error 0x80040610.

A built-in tool from Microsoft called “Scanpst.exe” or the Inbox Repair Tool is a simple way to fix the Outlook data file. It works by automatically fixing any problems it finds when it scans the data file. To be safe, we suggest that you make a copy of your data before you run this tool. After this is done, you can move on to the next steps:

1. Open the Windows Search tool, press the Win and S keys together.
2. Type “Task Manager” and press the Open button.
3. Right-click on Outlook in the Processes tab and choose End task.
4. Use File Explorer to go to the following place: X is the version of Outlook you are using. So, if you’re using Outlook 2016, click on the file called “Office 16.”
5. C:\Program Files (x86)\Microsoft Office and Microsoft Office X.
6. Find the file called “Scanpst.exe” and click on it.
7. Click the Browse button in the tool.
8. Now, find the Outlook data file (.pst) that needs fixing. If you are using Outlook 2019, Outlook 2016, or Outlook for Microsoft 365, go to the following place in the File Explorer:
   C:UsersusernameDocumentsOutlook FilesOutlook Files
9. If you have Outlook 2013, go to the following place. Replace “username” with the name you use to log in to Windows.
   C:\Users\username\AppData\Local\Microsoft\Outlook
10. Choose the .pst file and click the Start button. The tool will check the file for problems and try to fix any problems it finds. You can look through the repair log to see if there are any warnings about the problem.

Open Outlook in Safe Mode

1. Hold down CTRL and then double-click on the Outlook.exe app icon.
2. Now, you’ll get a message asking, “Do you want to start Outlook in Safe mode?” Click “Yes.”
3. On the next screen, choose the name of your Outlook profile and click OK.
4. Safe Mode will now be used to open Outlook. If the error 0x80040610, “The message being sent is bigger than the message size,” doesn’t happen in safe mode, it may be because of an Add-in. In that case, turn off add-ins for Outlook.

Increase PST File Size Limit

You might also have this problem if the PST file size limit has reached or passed the maximum size for the Outlook data file. If your PST file has reached or passed the limit, you can fix the problem by following these steps to raise it. But since this method uses the Registry Editor, we suggest making a backup of the Registry, just in case. After that, you can move on to the next steps:

1. Use the Task Manager as we said above to close Outlook.
2. Press the Win + R keys to open Run.
3. In Run, type “regedit” and press Enter.
4. In the UAC prompt, confirm what you want to do.
5. Once you are in the Registry Editor, go to the following spot. Replace “version>” with the version of Office you’re using right now.
   HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\PST
6. Choose New > DWORD (32-bit) Value when you right-click on the PST folder.
7. Use the name “MaxLargeFileSize” for the new DWORD value.
8. Right-click on the newly created value and enter the maximum file size in megabytes (MB) in the Value data section.
9. If you click OK, the changes will be saved and the Registry Editor will close.

Disable or Remove Problematic Add-ins

Add-ins are extra features and programs that can be added to Office programs to give you more functionality. Most of the time, they work quietly in the background, but sometimes they can’t work together or start to break down, which can cause problems like the one at hand. You can temporarily disable or remove the possible culprits to see if this is the case in your case. How to do it:

1. Click on the File tab after starting Outlook.
2. Select Options from the list on the left.
3. Now, choose Add-Ins from the menu on the left, and on the right side of the window, expand the Manage dropdown.
4. Click on the Go button after choosing COM Add-ins.
5. You should now see a list of the currently active add-ins. Uncheck the boxes next to each one to turn it off, and then click OK to save the changes. If you already have a suspect, you can just turn off the one you have and leave the other one on.
6. Last, restart Outlook and check to see if the problem is gone.
