Answer 1

Hi,
Which type of email account are you using? POP3, IMAP or Exchange?
Please open your Outlook and click on Send/Receive
tab, check if the Work Offline button is highlighted. If so click the button to deactivate it. Then, restart Outlook to check the result.
If Outlook was still stuck in Offline mode, please try to log into your webmail and check if you can send and receive emails using that site. If you can't, please contact your email service provider for help.
If you can get and send mail on the website, the mail server’s fine. Please try to install all patches for your Outlook. We can also try to create a new mail profile in Control Panel and configure your email account in the new mail profile to check if it
helps. To do this, please refer:

Hope this helps.
