Encountered with MS Outlook Timeout Error 0x8004210a - Read this Information

Microsoft Outlook is a versatile email client equipped with advanced synchronization capabilities that enable seamless access to emails stored on a central repository known as the Exchange Server. Outlook users are connected to multiple users and servers through specific configurations of port numbers and protocols. The Send/Receive operations are vital for ensuring smooth communication. However, sometimes issues can arise, preventing the expected Send & Receive process from completing due to various technical factors related to MS Outlook configurations. In this context, Outlook users may encounter the POP Server Timeout Error 0x8004210a, often caused by irregularities in the setup.

When an Outlook user encounters the POP Server Timeout Error 0x8004210a, there are typically three primary reasons to consider as possible causes:

Existence of any antivirus program might be disrupting the standard connection attempts for MS Outlook
Active Windows Firewall could pose as a hindrance to the normalized MS Outlook Send/Receive process
Improper configurations in the time-out settings of Exchange Server
Incorrect specification of port numbers in the MS Outlook email client

Measures to Rectify MS Outlook Timeout Error 0x8004210a

When you are aware of the reasons behind the 0x8004210a error, you can rectify these issues by applying some methods that are mentioned here:

Check the Internet connectivity :- Your first step should be to check whether the Outlook application is able to connect to the internet. Outlook can function in offline mode, allowing users to work without an internet connection. If Outlook is working in offline mode, it won't be able to send or receive emails until it's reconnected to the internet.
Remove suspicion emails from your Outlook mailbox :- If there are infected or corrupted emails in your mailbox, they can potentially disrupt the performance of your entire Outlook application and prevent it from sending or receiving emails. If you are aware of such emails, it's essential to delete them promptly to maintain the health and functionality of Outlook.
Disable your anti-virus program :- If your antivirus program is integrated with Outlook, it can potentially interfere with Outlook's performance. To mitigate this issue, consider disabling the antivirus software from scanning Outlook emails.
Delete the older account and create a new one :- If your Outlook account is irreparably damaged, your only option may be to delete the old account and create a new one. You can do this through the Control Panel settings.
1. Close Outlook and open the Control Panel.
2. Click Mail (Microsoft Outlook 2016.)
3. Click Email Accounts.
4. Click New and create a new account’s credentials.

After creating the account again, try to send some test emails to other account to test the connection.

In addition to the common troubleshooting steps, if the issue persists, you should configure the correct port numbers and server timeout settings. The server timeout error 0x8004210a occurs when the Send/Receive operation cannot be completed within the configured timeout limit. Additionally, you should check the port number settings for POP (Post Office Protocol), as the values for the POP port number vary when you configure SSL encryption settings. Let's go through these two troubleshooting tasks one by one:

Launch the MS Outlook application
Click the File menu followed by Info
Click the Account Settings tile and select the Account Settings option
Select the desired POP3 account and click the Change option

Turn the slider towards right-side to increase the Server Timeouts range

To Configure Server Port Numbers:

Follow the steps through 1 to 6 of Configure Time-Out Server Settings
Specify 995 to Incoming server (POP3) if you have marked This server requires an encrypted connection (SSL)
Specify 110 to Incoming server (POP3) if you haven't activated the This server requires an encrypted connection (SSL) field

Modifying these POP server configuration settings should resolve the POP Server Timeout Error 0x8004210a.
