I can't receive email in one of 7 accounts in Thunderbird 38.5.0. I think this started with the last update. When attempting to receive email, I get the message: There was an error downloading the following message: From .... Subject .... This message may contain a virus or there is not enough disk space. Skip message? I reply NO. I have received the message in a different account by having the sender resend it. No Virus, it is just text. I have about 330GB free space. I have deleted old emails and compacted folders. The largest folder is about 700MB. Other accounts from the same server are OK. Not sure what to do next.

The first time the message download is attempted and I reply NO, I get the following message: Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

Try to start *Windows* in safe mode with networking enabled.

- Win7 http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode

- XP http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx

Still in Windows safe mode, start Thunderbird in safe mode.

Does the problem go away?

I ended up deleting and recreating the account and it is now working. I have been using Thunderbird with this account for about 5 years and I can't explain why it stopped working in mid December. It's working now. Thanks for the update.
