What to do When Outlook Displays ‘Cannot Connect to Server’ Message?

Many users who use the services of Outlook may use Exchange server profiles to create an offline folder. This cached exchange mode of Outlook helps the users to make a file for offline use. The file generated is encrypted with unique settings which are located in your exchange server. This helps the user to access outlook even when offline. The only requirement to use this offline file is the authentication process.

But, sometimes this file cannot be created due to failed authentication. This happens when Outlook cannot connect to server. This Outlook screen displays a simple message.

“Cannot Start Microsoft Outlook. Cannot open outlook window. The set of folders cannot be opened.”
