Yesterday morning, everything was working fine. Yesterday afternoon, it wasn't. I use Comcast and Thunderbird. I can send e-mail using Thunderbird but no e-mail is downloading from Comcast. I can view my Comcast e-mail on their web site. I am using Pop3 but I read something about adding IMAP so I tried to do that but I kept getting an error. I'm trying to figure out whether this is a Comcast or a Thunderbird problem before the painful experience of calling Comcast support. Any ideas?

Hi all., can you please help.

- I cant receive emails ( no new emails in my mailbox ) - I "see" sent emails - but people reported that they receive email from me.

As an emergency I am using Roundcube Webmail 1.3.11 web email now, works fine. My hosting and provider of email address is reporting no problems at all.

Sending you screenshot of what is happening on my screen. I did reinstall Thunderbird, no result.

Can please somebody help ?

Running Thunderbird 75.8.0 on Windows 10 Pro Version 20H2 OS Build 19042.630

Using IMAP to download emails from Google Gmail:

Server settings: Server Name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication Method: OAuth2

Confirmed IMAP enable on Gmail and permission for Thunderbird to a access the Gmail account.

Details:

Have been using Thunderbird with Gmail for years with no problem. Just today it stopped downloading emails. Been trying several solutions on Mozilla support but no luck. Tried disabling firewall, also no change.

When I logged in this morning, I didn't receive new messages. When I sent a message as a test, it said that while the message was sent, it would not be saved. Something happened happened overnight, because it was fine when I logged off.

Long time thunderbird user. 78.5.0 has been functioning on up to date windows 10 laptop up until this morning. It will not retrieve any new mail. No error messages.

Tried reboot. Tried uninstall/reinstall. No change.

Thunderbird 68.12.0 on a windows 7 desktop on the same home network is working fine. Not sure what else to try here. Any thoughts?

Hello, I use Thunderbird (since years) version 78.5.0 under Windows 10. This morning all was ok, but this afternoon it refuses to collect my mail. I searched for the problem in help for Thunderbird and found a solution : in the pop email server setup I changed the security of the connection to None (it was SSL/TLS). And it works. My question is : do I now have a security problem ? Thanks.

When sending emails, TB has always filed them correctly in my IMAP sent folders. Today it comes up with a message

Your message was sent but a copy was not placed in your sent folder due to a network or file access errors

I can only save by selectic save to local folders.

Any ideas - it has completely cocked up my use of TB!!!!

Hello, Thunderbird has been updates automatically from v68.12.1 to v78.4.1 on my computer. Now the password is requested every time I launch Thunderbird. No password are registered in Option->Vie privée->Mots de passe enregistrés. The check box allowing to store the password to the password manager is not any more shown. Can you help me ?

After the most recent update, 78.4.0, I cannot receive emails. I can send emails. Also the folder icons changed from yellow to white. Erols.com (RCN) is my email host. I can still receive emails on my phone and through mail2web.com. I have tried turning off firewalls, both Webroot and the native one in Windows 10. I have tried uninstalling and reinstalling both latest version and an earlier version. I checked to make sure the proper password was still saved. When I hit the Get Messages button, there is a "Connected to pop.rcn.com..." in the bottom pane where the "unread" and "total" are listed. It just vanishes after a bit. Anybody got a cure?

I can no longer receive email, it worked fine up until yesterday, now a little blue circle keeps turning in the upper right hand corner like it is looking for my email, but I don't get them. I have checked everything your help section says to look at. I even did the one said says check your password, I picked the one in question and did what you said I removed it, closed Thunderbird and reopened and nothing it did not ask for my password like you said it would.

HELP? Becky Meyer

Using Thunderbird, since yesterday it is not possible to download my incoming emails anymore. And on another PC download is no problem. Sending email works fine. Help!! I looked at the error console in the extra menu, developers tools. The error console contains the following message: [Exception... "Component returned failure code: 0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH) [nsIXPCComponents_Utils.readUTF8URI]" nsresult: "0x80520001 (NS_ERROR_FILE_UNRECOGNIZED_PATH)" location: "JS frame :: resource://gre/modules/L10nRegistry.jsm :: L10nRegistry.loadSync :: line 658" data: no] 2 L10nRegistry.jsm:658:19 Successfully loaded OpenPGP library rnp.dll from C:\Program Files (x86)\Mozilla Thunderbird\rnp.dll RNPLib.jsm:49:13 [Exception... "Component returned failure code: 0x80520001

Can you tell me what to do? Thanks. Ron Jedema

Several people I know have called me with the same problem, all in the afternoon of the 30th of november.

Thunderbird sends mail and gives error mail cannot be save in the sent folder, but does not receive mail, not from private imap server, hotmail nor gmail. (has done for at least the past 10 years)

Updated the 64 bit windows 10 to the latest version with no avail, also in safe mode, no go (with thunderbird 78 and 84b)

Could this be because of a security certificate running out of date?

More than 6 different pc have this problem all in the afternoon of the 30th of November and othe pc are still synchronising, question is why?

Haven't been able to receive emails on my desktop since update last nite. I do receive emails on my phone, so Thunderbird seems to be the problem. I've rebooted computer 3 times + re-started T-bird. No new emails.

I've been using Thunderbird for over 10 years and suddenly yesterday after an update to 78.5.0 it stopped receiving emails. It also started to raise an error when I send an email "Your message was sent but a copy was not placed in your sent folder (Sent Mail) due to a network or file access errors."

When I select "Get all new messages", there is no response, no status message at the bottom of the window and no errors or other response.

I have rebooted and reinstalled Thunderbird - still no joy.

I have ESET Nod32 Antivirus and email still fails if I turn email scanning off.

I have several gmail accounts. They have worked for years. What changed?

Thunderbird 68.12.1 is working fine with these email accounts on a second computer I have.

Thank you, Mike

Hello All,

since yesterday evening Thunderbird 78.5 stopped synchronizing IMAP folders.

I have 26 accounts setup in Thunderbird from 4 different providers so it is not a settings issue.

Tried repairing a folder but with no luck. It remains empty with no error popping up at any time.

Tried starting Thunderbird with no add-ons but with no result.

Could you advise on further steps I can take?

Suddenly today no emails are downloading to any of my accounts in Thunderbird. I have several cox, gmail, and outlook accounts, and they all were working fine yesterday. I am still able to send emails from Thunderbird, just not see the incoming emails.

In the past few days, I've found that Thunderbird (config details below) has been unable to login to my Gmail accounts (3). Passwords have not changed and I can access them via Gmail/browser (Firefox). I see a status message saying "brittont0@gmail.com connected to imap.gmail.com ..." (and similar for the other accounts) but nothing downloads. I have a notebook with TBird and it has no problems, nor does my wife's. I've tried deleting the brittont0 account and re-installing it, but for that I get a message saying it cannot connect even though all the connection details look correct - Gmail settings as determined by Thunderbird and my name, email and password are all correct (ie same as used elsewhere). Any thoughts? I'd try down-versioning, but only have TB 68.6.0 installer and says my profile has been upgraded and I need to start again (I'd prefer not to). Is there a TB 78.4 or earlier installer available anywhere to try? Config details: TBird 78.5.0 32-bit OS: Win 10 home (desktop) Wired network connection (broadband) Eset 14.0.22.0 anti-virus My Gmail account says there are 1258 messages in the Inbox My notebook runs TB 78.4.0 on Win 10 home My wife's desktop runs TB 78.5.0 32-bit on Win 10 home

TB and GMail worked great last night. This morning it doesn't and hasn't worked all day. I've tried removing the gmail account from TB and when I try to re-add it in it says something like User Name or Password incorrect and can't login. I can login fine to my Google account through the browser and get to gmail.com fine also. I disabled ESET Anti-virus and that didn't help. Tried changing Google to use less secure apps and changing login to Normal, that didn't help either. I manually re-added my gmail account in TB hoping that might somehow help, but still it doesn't work.

My other email accounts in TB work fine, just the gmail account stopped working this morning. I've seen other posts today from people experiencing the same issue.

Any ideas would be greatly appreciated.

Thanks...
