The first thing you should ensure on finding that Microsoft Outlook Cannot Connect To The Server is that the email client is online. You might enter the right credentials, but if you cannot log in, it's possible that Outlook is offline. To fix this problem, follow these two steps.

• Navigate to the 'Send/Receive' tab in your Outlook.
• Next, find the option of 'Work Offline' and hit it.
• This option will disable the offline mode, and Outlook will connect to the server.
