Dear Community members,



Recently the admins switched to Exchange 2019 and since then my Outlook 2013 stopped connecting to the Exchange server --- Outlook starts in the Disconnected state (the lower-right corner of the Outlook windows displays "Disconnected").

I installed all the latest updates for Office 2013 and Outlook 2013:


I tried to follow Outlook connection issues with Exchange mailboxes because of the RPC encryption requirement - Exchange | Microsoft Docs and create a new mail profile for the same Exchange server but got the "The connection to the Microsoft Exchange Server is unavailable. Outlook must be online or connected to complete this action" error message:



Local admins couldn't help me and fix the connection.

Can you help me to investigate the root cause of the issue, please?

Thank you.
