This problem caused Outlook error :
Code:
Task 'Synchronizing subscribed folders for ---@----.' reported error (0x800CCC0E) : 'Outlook cannot synchronize subscribed
folders for ---@----. Error: Cannot connect to the server. If you continue to receive this message, contact your server
administrator or Internet service provider (ISP).'
How i can resolve this problem.
Thank you.
