- Product
- Outlook 2019
- Device & OS
- not provided
- Scenario
- Attempting to download and view new incoming emails using the Outlook desktop application.
- Observed behavior
- New emails fail to arrive in the inbox, potentially accompanied by synchronization errors or a completely stagnant inbox.
Check your network connection to ensure you are online, and verify that the 'Work Offline' mode is disabled under the Send/Receive tab in Outlook.
Verify Account and Incoming Server Settings
Checking your mail server configuration ensures Outlook is properly communicating with your email provider to fetch new messages.
Incorrect IMAP or POP server settings are the most common reason for incoming mail failures. Sending a test email to your own address can help quickly determine if the issue is isolated to incoming connections.
Click 'New Email', enter your own email address in the 'To' field, and click 'Send'. Check if the message bounces back with an error or arrives in your inbox.
Navigate to 'File' > 'Info' and click on 'Account Settings', then select 'Account Settings' again from the dropdown menu.
Double-click your email account. Verify that the 'Incoming mail server' address and port numbers match the settings provided by your email host.
Check Mailbox Quota and Update Office
A full mailbox prevents new emails from being delivered, while outdated software can cause sync glitches.
Temporarily Disable Outlook Add-ins
Third-party add-ins can sometimes conflict with Outlook's send/receive processes.
Boost Your Productivity with WPS Office
While resolving Outlook issues can be frustrating, managing your documents shouldn't be. Consider switching to WPS Office as a free, lightweight, and highly compatible alternative for all your Word, Excel, and PowerPoint files.

Frequently Asked Questions
Why is my Outlook connected but not receiving emails?
This can happen if your mailbox storage quota is full, there are incorrect incoming server settings, or if third-party add-ins are interfering with the background sync process.
How do I know if my Outlook mailbox is full?
You can check your storage by going to File > Info in Outlook, where a Mailbox Cleanup tool shows your current storage capacity, or by logging into your webmail account online.
Can working offline stop emails from coming in?
Yes. If Outlook is in offline mode, it disconnects from the server. Go to the Send/Receive tab and make sure the 'Work Offline' button is not shaded or highlighted.
