unable to open my emails on my iMac desktop

[winterwonderland]

I can not open my email account on my iMac desk top. The circle of doom keeps going around. I can open it on my iPhone. I only have a small phone and can not see my messages very well why is this happening on my desk top. 

Anyone have any suggestions for a fix please 

Many thanks

So long as the iMac OS is up to date and the browser is up to date and supported, e.g. Chrome, Firefox, Edge or Safari then a browser reset will usually get things working again.

Either try a different browser or if you need help with carrying out a browser reset then let me know the details of the iMac OS and browser and I'll advise.
