Thanks guys.

Here is what the hosting company said and I asked them if they can reboot the mail server we use. We have 2 servers, forum and mail. I will update as appropriate..

Hello,
We have checked, and the server in question has an uptime of 611 days.
I see most of the server memory is being used by the Windows Remote Desktop Services. It has been idle for over 400 days, which can cause resource drain as it's currently using 80 percent of your server memory.
The first thing I would recommend is logging out any remote desktop sessions you have, as that should free up memory. If still seeing issues, you should reboot the server.
Please let us know if any further assistance is required.
Thanks,
