Closed it and the computer last night. Booted up this morning as normal. On opening Thunderbird however the Windows "Working" symbol did its circling for ages.
It will not read (IMAP) from the host. There are several emails there that I can see through Webmail. I have increased its cache size and emptied the Junk folders. So capacity shouldn't be the issue.
In desperation I deleted TB, though not its stored data. Rebooted. Downloaded from Mozilla, opened it, all emails still there, still doesn't read. I can send from one domain to another, which gives a second problem. It gives an error message that it cannot write to the "Sent" folder. It does arrive at the host.
Clicking to Read or Read all, it doesn't give any error message saying it can't write to disc here.
Any ideas anyone, please?
