Check Internet Connection and Mailbox Server Status<\/strong><\/h3><p>The first thing to do is check your system&rsquo;s network status. It should be online and connected to the Internet. For this, open a web browser and visit any website. If your internet connection speed is low, you can restart your router or contact your service provider for assistance.<\/p><p>Also, try to log in to Outlook Web app to check the server status. If you can&rsquo;t log in, contact the administrator for more help. If you&rsquo;re able to login to the OWA, it indicates that the server is online and the problem is with your Outlook client, system, or network.<\/p><h3 class=\"wp-block-heading\"><strong>2. Check Work Offline Status<\/strong><\/h3><p>Outlook features a&nbsp;<strong>Work Offline<\/strong>&nbsp;option that allows users to disconnect Outlook from the Exchange Server and continue their work offline without getting disturbed by incoming emails. This also comes in handy when the network is unreliable or poor. If the Work Offline option is enabled, Outlook will show the status as disconnected from the Exchange Server. To check and disable Work Offline option, follow the instructions given below:<\/p><ul class=\"wp-block-list\">\n<li>Go to the&nbsp;<strong>Send\/Receive&nbsp;<\/strong>tab.<\/li>\n\n\n\n<li>Check if the&nbsp;<strong>Work Offline<\/strong>&nbsp;option is enabled.
