If you're experiencing an Outlook send/receive error that won't go away, you can try the following troubleshooting steps:

Check your internet connection: Make sure your internet connection is stable and that you're connected to the network.

Verify your email account settings: Go to File > Account Settings > Account Settings. Check that your email account is listed and its settings are correct.

Disable antivirus and firewall temporarily: Sometimes, antivirus and firewall programs can interfere with email sending and receiving. Temporarily disable them to see if that resolves the issue.

Delete and recreate your email account: Remove your email account from Outlook and then set it up again.

Repair your Outlook installation: Go to Control Panel > Programs and Features > Microsoft Office (or Microsoft 365) > Change > Quick Repair. If that doesn't work, try Online Repair.

Create a new Outlook profile: Your Outlook profile may be corrupted. Create a new profile and see if the issue persists.

Check your email server status: Check with your email provider to see if there are any issues with their servers.

Reset send/receive settings: Go to File > Options > Advanced > Send/Receive > Send/Receive Groups. Click on All Accounts and then click on Edit. In the new window, click on the account and click on the Reset Defaults button. For more information visit our website.
