What you need to know about Exchange server 2010?
Exchange 2010 reached the end of its support life cycle on October 13th 2020. This announcement means that though you can keep using Exchange 2010, you no longer can receive security updates, bug fixes and technical support for any issues. If you continue to use Exchange 2010, your data will be highly vulnerable to security flaws, ransomware threats, and you may experience poor performance. As a result, it is strongly recommended to migrate Exchange 2010 to 2019, Office 365 or export your 2010 server mailboxes to PST files. A PST (Personal Storage Table) file is commonly used to store data offline and can be easily imported into other email clients such as Microsoft Outlook.
