I have some Win XP machines that are used for connection to an older ERP. They use Outlook 2010 with all the latest updates. We were on an Exchange 2013 email platform and it was working. Our email provider recently migrated to Exchange 2016 and now the Windows XP computers cannot connect. When adding a new profile and connecting as an Exchange over https client, an error is received that 'must be connected or online'. We have run the commands on the server to specify the certificate used for connection, but this has not resolved the issue. Is there any other options for settings on the computer or the server that may help?
