Mail will not load emails.
It takes a long time to load them or it will not load them at all. I have to Quit mail, open it again and then click on the email to see it. What is the problem and what can I do?
iMac 27″, macOS 10.13

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
