Have to restart outlook to get new mail

Frustrating! There are a few reasons why you might need to restart Outlook to get new mail. Here are some possible causes and solutions:

1. Outlook not checking for new mail: Make sure that Outlook is set to check for new mail regularly. Go to File > Options > Advanced, and ensure that the "Schedule an automatic send/receive every [X] minutes" option is enabled.
2. Outlook cache issue: Sometimes, Outlook's cache can become outdated, causing issues with receiving new mail. Try restarting Outlook to clear the cache.
3. Server-side issue: It's possible that the issue is on the server-side, and restarting Outlook helps to refresh the connection. Try restarting Outlook and see if you receive new mail.
4. Add-in or plugin conflict: If you have any add-ins or plugins installed, they might be causing the issue. Try disabling them one by one to see if the problem persists.
5. Outlook profile issue: If you're using a shared mailbox or have multiple email accounts set up in Outlook, it's possible that the profile is causing the issue. Try creating a new Outlook profile or resetting the existing one.
6. Windows update or system issue: If you've recently installed a Windows update or experienced a system issue, it might be causing the problem. Try restarting your computer and see if the issue persists.

To troubleshoot the issue, you can try the following:

1. Restart Outlook and see if you receive new mail.
2. Check the Outlook journal to see if there are any errors or issues with the connection.
3. Try sending a test email to yourself to see if the issue is specific to receiving mail or if it's a general connectivity issue.
4. If you're using a Microsoft Exchange account, try checking the Exchange server's status page to see if there are any known issues.

If none of these solutions work, you can try contacting your email administrator or Microsoft support for further assistance.
