On startup TB pops an error box up saying ' There is no email program associated to perform this action'. When dismissed TB continues to open normally. No other errors seen during operation.

I have checked my Win 10 Control Panel Apps options. TB is the email default. MailTo, file type .eml and all other settings I can see are set to TB as well.

Receiving email notifications in Thunderbird but they are not showing in my three different inboxes. Can read them via my mobile phone and if I log into my talktalk webmail? I am currently travelling and logged into a different IPS. There was no problem for the first couple of days. Could this be connected to the issue?

I can't send email from comcast.net account. Outgoing server (SMPT) ERROR. Comcast said problem with mozilla. What should password be for comcast smtp://smtp.comcast.net (smtp://smtp.comcast.net)?

I just updated to version 115.11.1 and now if I delete a message in my unified Inbox, sometimes it deletes and quickly comes back and sometimes it just stays there and I cannot delete again (delete is greyed out). Sometimes it does go into trash but still shows in inbox. In my server settings for that email I have the deleted email set to go to trash for that inbox. Suggestions?

I might give you more info..it seems now if I delete the message either by right clicking or top menu delete, it sends to the trash but stays in the inbox (sometimes it goes away but comes right back). If it stays in the deleted unified folder and I empty that trash folder it comes off the inbox. I have W10..and mail is from Yahoo Cox conversion that was working fine until this update today. Yahoo does seem to be much slower than Cox was so I am trying to be patient and wait but it stays in the inbox until described. The bottom taskbar icon still shows a mail in the inbox too even though it is in trash or even emptied. I have to close TB and go back or say to close window for this new mail icon to clear.

I have also discovered if i send an email from my iphone, eventually it comes into TB but if I delete it on my phone it is gone in TB but is NOT in TB trash but it does eventually show on my iPhone trash...the only way i could see this is to remove Trash from that email account in the unified section and then it shows in the regular trash for that email...seems maybe the unified folders have issues after this update ..this is getting so frustrating...and surprised there has been no response to this help question either..I checked my email here and it is correct..

In box emails on my desktop computer disappear without trace, mail that is in deleted & archive accounts are still there. These emails are still on the server as all these mails, thankfully, are my laptop

In Thunderbird, the content of all my Sent emails has disappeared. When I went to my Sent folder, the sent emails were listed but when I clicked on any of the listed emails, the body was blank. I right-clicked the Sent folder, selected Properties and then clicked Repair Folder. My Sent folder now lists messages that I sent today and yesterday and I can see the content of those emails... but none of the previous Sent emails are listed.

My email history is essential to my business. Unfortunately, I never figured out how to back up the Thunderbird file incrementally so I don't have a backup. Is there any way that I can recover my Thunderbird Sent emails?

P.S. If my Thunderbird Sent email history is unrecoverable, then I think I need to find a different email client that I can back up incrementally... or should I switch to directly using Outlook online in my Microsoft 365?

I sent a message a while back about slowness with 115, which I had to download because I had a crash.

There were various suggestions, but no solutions to the excessive slowness with 115. This culminated to day in a long 'no reply' mail which suggested the issue might be the virus checker.....

I checked again the various messages about 115 - most were archived, only one month since they were posted!!

Is there an issue with 115?? I saw a thread which asked was I having issues with it, my answer is yes, is there nobody out there with a suggestion??

I've just started getting error messages that I need to enter my password to send emails. I've tried that but it still keeps saying unable to connect to the server. This has been happening for about two days now. I've tried updating Thunderbird, restarting Thunderbird and restarting my PC. None of this has worked. I made no changes to my system, software or home network. Any help would be appreciated. Thanks, Dave

I suffered a BSOD on my fully up to date Win10 Pro (v 22H2, build 19045.4474)

Upon rebooting, Thunderbird is failing to open. The error message is:

   Unable to open the folder Inbox on xxx@example.com because it is in use by some other operation. Please wait for that operation to finish and then select the folder again.

There is no other process using the Inbox folder. I have rebooted and the error message persists. It looks to me like the more correct message would be that the Inbox or the profile is corrupted.

I see other threads asking how to restore a corrupted profile, but none of the answers are very useful. They all see to be tips on how to restore a backup of the profile at %APPDATA%\Thunderbird\Profiles.

If I had a backup of that folder, I wouldn't need to ask how to recover a Profile after a crash.

If it helps at all, when I opened the Error Console in Thunderbird, I see the following messages:

There must be some tool that validates the Profile independently of Thunderbird.

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

I keep getting this message sporadically: "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.hughes.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again."

I sent messages yesterday with no problem!

I can't see any issue with the SMTP settings. I've tried troubleshooting mode.

I'm at a loss, and I'm being bounced around by a ping pong by Comcast and Optimum. Let me state some facts. 1. The error I'm reporting here, I have NEVER EVER seen before. 2. I have 2 email comcast email addresses, they have worked with Thunderbird for over 15 years- no issues. 3. Optimum is my ISP for the past 5 yrs- no issues like this. I don't have an email address w/them. Seems they don't provide them anymore I was told by their rep!

Earlier last week I noticed I was not receiving emails at all from on my iPhone. I use the iPhone Mail application for email.

I opened Tbird this morning and saw this WEIRD message for both comcast email addresses.

Sending of password for user xxx@comcast.net did not succeed. Mail server mail.comcast.net responded: [AUTH] Temporarily blacklisted IP Address - try again later

Then the following window in Tbird appears both accounts each.

Login to server mail.comcast.net with username xxx@comcast.net failed Retry, Enter New Password, Cancel

No idea what the above blacklist error means.

I called Comcast. We checked/reset the passwords on the accounts in the comcast webmail, I changed them in Thunderbird. I checked both inboxes, and there were over 40 emails I never received in Tbird, nor on my phone, inside Comast's webmail.

Using comcast webmail on my PC, I am able to send emails to myself from both accounts, and reply. My friends are able to send me emails to both accounts. However I can only see the emails on my phone, NOT in Thunderbird.

Here's the more weird part.

My primary comcast (#1) email address on my phone works ONLY when I'm using my cellular data. If I connect to my ISPs router, I cannot send/receive email at all from comcast, and using Apple's mail app, I cannot send email using the gmail account that I have in Mail also. The gmail is independent from comcast.

If I disconnect from Optimum WiFi router, then the following works: 1. Gmail- can send/receive email 2. Comcast email #1 (Primary)- can send and receive emails from/to anyone 3. Comcast email #2- can only receive email, it cannot send at all.

When connected to my WiFi both comcasts read same error in Mail app with "Cannot Get Mail, xxx is currently unavailable"

And no matter what I do- Thunderbird continues to give me the above error and nothing can be sent OR received in Thunderbird.

I have no idea where to go on this one.

Thanks in advance.

Hi, I downloaded messages from an university account to a local folder created in Thunderbird. After doing so, I deleted the online messages to make room for more messages, since the university account has very limited space. However, the donwnloaded messages are only visible in preview mode, with a short truncated text. If I click on them it shows a blank message, and attachements are missing too. I already did this before and it worked well. Any idea what was wrong this time? Is there still any way to fix those messages (they are not available online anymore)? Thanks!

When writing an email message, periodically the cursor jumps to the subject line.

A prior thread recommended unchecking the hardware acceleration option at Settings / General / Indexing -- though that has not worked for me.

Does anyone have a solution?

Please provide guidance on how to fix this issue. When I attempt to transmit an email I get the error: "Add security exception, Location: smtp.aol.com:465 This site attempts to identify itself with invalid information." When I Confirm Security Exception I get: "Send Message Error: Sending of the message failed. Peer Certificate issuer is not recognized. The configuration related to smtp.aol.com must be corrected." I cannot receive any emails either. No error message just no new emails since 5/29/2024. I have verified the settings needed and checked my system that they are correct. As this happened after an update I think this is your bug.

Two related problems I think:

1) I have never used the Archive facility, and I've unchecked the box in the Copies & Folders | Message Archives | Keep message archives in - for all the mailboxes. But I'm still getting *some* messages appearing in the Archives mailbox that now has no subfolders. And I never type "A" when reading a message. Some messages just appear there. They are duplicated in the Unified Folders.

2) On a random basis (every couple of days) the Archives folder gets several blank messages the date of 12/31/1969 that I can't delete or read. They can't be marked as read either so they stay in bold. And a little while later they're gone.

I am running Total Defense as an anti-malware, and I saw elsewhere the suggestion to turn off scan of the mailboxes, but wouldn't that leave me vulnerable to malware that comes in via emails?

Any idea what's going on? TIA!

Hi, I know 95% likely NOT to be Thunderbird but hoped someone might have some advise.

With TSOHost & they recently migrated me to xxxxxxxxxxxx.prod.sxb1.secureserver.net (no choice) I think this is a GoDaddy server.

emails use to Go instantly (talking about the delay between pressing send & it going, so I can go on to the next. Not how long it takes to get to the received. Now 4 to 10 seconds, I guess 6 or 7 seconds on average. Short emails, no attachments, size seems to make no difference.

SSL & ports etc. all seem fine, it works, just slow. Not changed anything else in TB apart from the server name.

Is faster direct from webmail but prob. around 4 seconds.

Thankfully receiving is just as fast as before, again the update of what is shown, not from X to Y. TSOHost once moved me in error & I had similar slow but also on receive, might open TB & it was 10 - 20 seconds, I think even longer, before incoming were show & updated. I got them to move me back. I think then it was GoDaddy underneath. TSOHost say its down to the client, which seems unlikely if the day before migration it was OK.

Any advise/ideas. May not seem a lot but doing through lots of short emails, it does slow you down.

Can't see how virus detection could be involved, as nothing changed, perhaps a difference server, Windows defender is doing some more stuff, wild guess?
