[v24.1.0] I am unable to make any changes to any account's server settings, because when I try to OK them, I get a message similar to the following:
The Local Directory path "N:\apps\7.Admin\Thunderbird\Data\profile\accounts\{account}" is not suitable for message storage. Please choose another directory.
I don't know when this issue started, since I haven't tried to make changes for months. Needless to say, all the accounts whose messages are stored in their 'not suitable' {account} folder work perfectly.
What is wrong with the path (now)? Why has in become 'not suitable'?
With thanks.
