iMac 2010, mail has stopped sending or receiving after long shutdown
Hi, this is a strange one. As we were out of the country my iMac was shut down for 4 months. Now it won't send or receive mail in Mail as it used to before the shut down. It's running iOS High Sierra 10.13.6. it won't update any further.
However, if I log into Google Chrome, then I can get or send email via that, so it's not my ISP (Vodafone). Also I can send and receive mail on my other devices (iPhoneX, iPad).
In Mail preferences it shows that Mail for my gmail account is off line. Any idea's how to get it on line? I've tried quitting and restarting mail.
In Mail preferences it shows that iCloud is on line, but when I click on it, it says no new mail available, it doesn't send either.
When I've queried Google on line, it asks for my password, but when I enter it I get an error message 400, sayings it's an invalid request!
Any ideas on what to do would be gratefully received! Thank you.
Best wishes Amer
iMac
