Identifying the Issue
The persistent error message "The email system had a problem processing this message. It won't try to deliver this message again" signals two dominant issues you might be encountering with your Outlook platform. Understanding the underlying problems will help target an appropriate fix.
Server Issue Causing Inability to Send Email
The first issue lies within the server. The Outlook server attempts to transmit the email, but the message fails to go through. This failure isn't a problem with the email content or the receiver's address but a server glitch, which might cause your emails to misfire and not move to the designated address. This problem is external and depends on the server-side response to your email attempts.
Data File Synchronization Issue Between Email Account and Data File
The second prospective issue may be data file synchronization. If your email account and data files are not synchronized properly, it can lead to problems in email processing. Your data file and email account require matching for smooth email transmissions. If the data file is not attuned to the email account, it can cause the email system to experience problems in processing messages, including failures to resend messages. A breakdown in this synchronization process can cause the system to reject your emails and return the error message.
Resolving with Correct Email Account and Data File Synchronization
Addressing the synchronization issue between your email account and data file can effectively resolve this Outlook server issue. By setting the matching email account and data file as default, the integrated Outlook system will process and transmit the emails successfully. Below is a step-by-step guide to help you manually synchronize your Outlook data files.
Open Outlook
Start by launching the Outlook application on your device. Ensure that the application is running in its maximized state to aids in quickly accessing the needed menus and settings.
Navigate to “File” and “Info” Section
Once the Outlook app is open, navigate to the "File" menu located at the top-left corner of the application. After clicking on "File", move your cursor downwards to the "Info" section and click to open it.
Expand “Account Settings” and Choose “Account settings“
In the "Info" panel, you will find "Account Settings". Click on it to expand the menu and select "Account settings" from the dropdown menu.
Set the Correct Mail ID and Associated Data File as Default in Respective Sections
Showing up next is a window displaying multiple tabs, including Email and Data Files. If you have multiple email accounts, select the correct mail ID from which you are trying to send the email and click "Set as Default". Then, move to the "Data Files" tab and locate the data file named according to the mail ID. Select it and click "Set as Default". Once refreshed, the synchronized email account and data file will seamlessly process, send, and receive Outlook emails.
Repairing the Data File
Outlook has an in-built repair feature that can help fix the errors in your data file and resolve the issue of unsuccessful delivery of the emails. Follow these steps to use this feature:
Access “Account Settings” from Outlook Menu
Navigate to the Outlook menu bar. Here, you will find the "Account settings" option on the right-hand pane. Click on the option to expand the settings.
Navigate to “Data Files” Section
In the "Account Settings" window, proceed straight to the "Data Files" section. If you are operating multiple email accounts, you will notice several entries here.
Select the Email ID Account
From the disclosed entries under the "Data Files" section, select the appropriate email account that is causing the trouble. This should correlate with the email account you had previously set as default.
Use “Repair” Function for the Email File
After selecting the correct email ID account, look for the "Repair" button in the same window. Click on this button to initiate the repair process for the selected data file. It takes a few seconds for the email account data file to repair. Once completed, try sending emails again to ascertain whether the problem has been resolved.
Compacting Data Files in Outlook
Besides repairing the data file, compacting the data file can also aid in rectifying the email delivery issue in Outlook. Compacting the data files reduces their size, which may facilitate smoother and faster processing. Here is how to compact your data files:
Access “Account Settings” and “Data Files” Area
First, launch the Outlook application and open the "Account Settings" once again. Now, navigate to the "Data Files" section from the multiple tabs displayed in the "Account Settings" window.
Select the Appropriate Data File
In the "Data Files" section, you will find the list of data files associated with your email accounts. Look for and select the relevant data file.
Use “Settings” and “Compact” Function to Make the Email Data File More Compact
After selecting the data file, click on "Settings" to access further options. In the data file settings, look for the "Compact" option and click on it. This action will initiate the compacting process of the selected email data file. The time taken for completion might vary, depending on the file size. Once compacted, you should be able to send your emails without any more trouble.
