If you are using Wi-Fi, switch to a wired connection to increase reliability.

If your internet is working properly, proceed to the next steps.

Ensure that these settings precisely match those provided by your email provider because any variations may result in communication errors.

3. Dealing with suspicious emails 

Delete any email that seems suspicious or like spam because there is malware or corrupted items in them that interfere with Outlook’s ability to work.

4. Consider Antivirus Interference

Turn off your antivirus software temporarily to see if it is unintentionally suppressing Outlook’s communications.

If Outlook is running all right without the antivirus, then adjust Outlook’s settings to allow Outlook in.

If this problem continues, reactivate the antivirus, and proceed to other troubleshooting steps.

5. Review Firewall Settings

Verify that essential Outlook files, such as Outlook.exe, are allowed to access the internet through your firewall.

Consult your firewall’s documentation or seek assistance from your IT support for specific configuration steps.

6. Launch Outlook in Safe Mode:

Disable add-ins and extensions that might conflict with Outlook’s core operations by starting Outlook in safe mode.

Extend the server timeout period to prevent connection errors during email operations, especially if dealing with slow internet connections or large email files.
