I have several email accounts provided via the same ISP. I am having problems downloading emails in one account in Thunderbird - messages do not down load and I receive an error message saying: There was an error downloading the following message: From: <sender name and email address> Subject: <subject line header> This message may contain a virus or there is not enough disk space. Skip this message? Yes / No If Yes is selected, the message then appears for the next email being downloaded to Thunderbird. Messages are being downloaded from the same ISP in the other accounts. I have tried repairing the folder and compacting. I also tried in Thunderbird Safe Mode, but none of these have made any difference. The emails that are not downloading are readable in the webmail application Any ideas please on how I can fix this problem (it appeared today and is the first time I've seen it) Thanks
