Today is June 22nd 2026 , I was busy all weekend and I just checked my mail this morning , I noticed that the last email I got was Thursday June 18th 2026 , so I right clicked and clicked on "Get Messages" , suddenly I have about 40 emails , dating from the 19th to today , I have complained before about having issues with emails being a day or so late and was told that is when they were sent .... I am calling BS on that response and repeating my claim that something is WRONG with Thunderbird and how (or IF) it recieves emails , because there is no way that ALL the emails I normally get all decided at once to wait to send them to me till today (and I only got them because I clicked on Get Messages , otherwise I most likely still wouldn't have recieved any emails for several days from the date they were supposed to show up)

I can't be the only one with this issue , so hopefully someone has looked into this and come up with a actual FIX , , I have had this email program since Windows stopped Windows 10 Mail and honestly , since its been out for years prior to that , I would think it wouldn't still be buggy as it is , there are lots of features that are just combersome to use (like mass deleting emails by Name) all the way to just actually getting emails on time when they were actually sent (I have literally been on the phone with someone and they send me a email , and I don't get it for hours or sometimes days or sometimes not at all , and they are from people I have recieved emails from before and are part of my address book , so I should get them within minutes at most , not days or never ...

I am about ready to go find something else that is relaiable (and looks better , as I can't even add one of my pictures as a Background , and Light/Dark mode sucks as far as looks goes unless you are some GOTH person or something) and actually user friendly (when I swtiched to this email program it was better than most of the others offered at the time , but honestly , it has never improved and has remained unfinished as far as I am concerned) , it says it "updates" all the time , but I have not noticed ANY improvements in Functionality or looks since I first downloaded it , and for as long as Thunderbird has been available , it should not still be in Beta form and actually function at least as well as Microsoft's outdated emails programs did , but as of this ongoing issue , it is still slow and clunky , it may or may not send you emails depending on the day , and is a pain to navigate things that should be easily accessible on the main page with a simple click , again I'm comparing it to Outlook Express which has been obsolete for years , and Windows 10 Mail because as old as they are , they functioned much better than this email ever has and look much better , at least they allowed personal pictures for a Background

If you don't have a actual FIX for this ongoing issue , then I think it's time for me to move on and find something that actually functions like a email program should , by actually being able to recieve emails faster than Pony Express , which was last used because it was too slow over 165 years ago

If you DO have a FIX for this ongoing issue of not recieving emails when they were actually sent (I complained about this exact issue back in January) , not days later , or being able to close Thunderbird and still get emails alerts (you know like Microsoft has for years , and as much as I dislike Microsoft and their policies and FORCED Feature Windows Updates that screw up everything , at least they had a decent and functional email program since Windows 95 through Windows 10 Mail , but all they offer now is Outlook and I don't do online emails , I want it on my Desktop , which is why I went to Thunderbird in the first place) , maybe since they discontinued theirs , you could just copy/paste everything from it and call it Thunderbird

At least then it would work like it should , and look better , and actually not have to just minimize it in the taskbar so you will know at some point that you got a email , or to make it automatically start when Windows does , so I don't have to manually open it every time I restart my PC , since I have yet to find a setting for that , or if it is there its most likely hidden behind 40 other things you need to open to get to it , even though most likely the email alert sound never happens , maybe 2 times a month if I'm lucky , and even if it is several days late , (like I said 40 different people/companies didn't suddenly decide to wait 3 or more days to all send their emails at once , and only after I clicked Get Messages , oh , by the way , they are EMAILS NOT MESSAGES , a Message is a Text or Chat , a Email is a Email , maybe that is the issue , it doesn't know what its looking for)

As mentioned this has been a ongoing issue that I have complained about before , with no solution , and that no one here seems to want to address or actually FIX or even let me know they are working on a solution (which it seems like no one is) , so I'm tired of complaining to deaf ears , Helen Keller would have figured out what is wrong by now and she is Deaf , Blind and Dead ... When I am expecting a email from a Doctor that has info on a test or something , I need it when they send it , not days later or never .... I keep missing important emails because this program is and has been iffy at best since I have had it ...

I understand that the majority of the Staff for Thunderbird is Volunteers , but it just seems like no one cares what users experience and just brush it off and forget about it , and that is the issue I am and have been feeling with Support .... Not trying to be a jerk , I'm just frustrated with the lack of concern with how this program has and still does function

Thanks ..... Jim

For some reason all my emails contained in the inbox keep moving to the trash box by themselves. I have to manually move them back to the inbox. This includes read and unread messages. anyone know how to stop this? V 152.0 64 bit.

E-Mail messages are in Xfinity, but do not come to Mozilla Thunderbird. Not having access to Mozilla email, prevents messages to be sent from Xfinity. I also cannot send messages from web sites. brucelowrey@comcast.net

A weird thing has started happening to my Thunderbird inbox in the last couple of days. Emails are showing as from a totally different sender. For example, a Google search on Sondheim has been "sent" by EDF (my electricity supplier) and some Groupon emails are showing as coming from people I correspond with. Also a Keto bread recipe from a low carb group I belong to has been "sent" by one of my work clients! More weirdly, I copied them into a subfolder on my inbox and they then appeared correctly. I have tried repairing the folder but it made no difference.

I have a Yahoo.ca email address and have been using Thunderbird to retrieve my email for years. For some reason, a window now pops up to Rogers.com and they want me to log in there. This is not a Rogers email address and it is separate from Rogers. I had this issue before and this forum managed to get me back. My settings are correct. I have deleted the profile 5 times and added it back after a computer restart and still nothing.

Even though I have Thunderbird configured to leave messages on the server after downloading it still deletes them from the server. Is this a bug in v146? New user.

I use Thunderbird on a Mac, where Gmail is my default email. When I try to send an email, it often takes 10 tries before it goes through, due to timeouts. How can I fix this?

Hello, I can't receive any of my e-mails. I can send e-mails out now. Plus I can put in my password to log into my e-mail. This has been a headache for me, I have been with Thunder Bird for years.

I also get a boxes that says : Unable to write the email to the mailbox. It says to make sure the file system allows me to write privileges, and I have enough disk space to copy the mailbox. I have enough space on my computer system and all. Another box that says my e-mail is being processed. Please wait until processing is complete to get messages. I did e-mail you yesterday on these issues. As I said I can e-mail messages out now also log into my e-mail with my password. Thanks, Chris

To Whom it concerns, It has been about 4-5 days since I can't receive my e-mail. I have e-mail you different times with errors coming up. When I open my mail since yesterday an error now says error with acct. cray9@oh.rr.com. Another error occurred with the POP3mail server. The mailbox closes. Then a box comes up Thunder Bird crash reporter then I can put why and then restart my e-mail. It does try to load my e-mail then stops. And now my password box doesn't come up to put my password in. Last it says connection to mail.twc.com was reset then once again the mailbox closes. Please help, I have been a customer with Thunder Bird for years. Thank you!!

To whom it concerns, It just happened yesterday June 11,2026. I put in my password to my e-mail to open it and it stated that my e-mail account is being processed. Said to wait until processing is complete to get messages. I have never had this issue, I been with Thunder Bird e-mail for years. It isn't even showing my e-mails that I had in my inbox on my e-mail. If you can please help, I need my e-mail up and going. Thank you, Chris Note, it also said that Thunder Bird had crashed in a box, they wanted to know what page I was on. I am not understanding this.

Hello,

For a few days everything worked perfectly. Now suddenly I cannot fetch any emails on neither Thunderbird for android nor Thunderbird on Ubuntu. Both latest versions at time of writing. Sending mails works. Another email client works, another email address from the same server (but different domain) does work.

Any ideas what I can do?

Thanks in advance. I'm trying to get Thunderbird setup with an outlook.com email address. All the default server settings look fine. I know the email address is good since I can login via a web browser. Cookies enabled and all the other recommended settings including app password. Yet it keeps saying Unable to log into the server. Has anyone successfully done this with the latest version of Thunderbird. I'm on Zorin 18 Pro.

Regards,

Mark Verhyden

I am experiencing a problem with Thunderbird for Android.

My setup:

• Smartphone: Samsung Galaxy S23 Ultra (SM-S918B)
• Android version: Android 16
• Computer: Windows PC
• Desktop email client: Thunderbird for Windows (latest version)
• Email accounts are configured and working correctly on the Windows version of Thunderbird.

The issue concerns the Android application. Despite using the same email address, login credentials and server settings that work correctly on my Windows computer, I am unable to properly configure or synchronize the account in Thunderbird for Android.

The desktop version connects without any issues, while the Android application either rejects the settings or fails to synchronize properly.

I have already:

• verified the email address and password,
• confirmed that the same credentials work on the Windows version,
• checked the incoming and outgoing server settings,
• reinstalled the Android application,
• ensured that the device has an active internet connection.

Could you please advise what additional steps I should take to resolve the issue?

Thank you in advance for your assistance.

Kind regards,

Did I dream seeing an ad for a new system for sorting incoming emails to what I would call folders, but I think it had sections like Work, Home, Family etc.? Can't find anything on it. I would love to be able to park stuff in separate folders without me actually doing it!

When I try to access my e-mails I am getting message." Login to server pop.tiscali.co.uk with username [redacted]@tiscali.co.uk failed." Nothing I do helps

With three accounts, if the first account is set to folder poll frequency = 15min and the others are set to never, the first account does not poll its folders after 15 minutes. The bug workaround is to set all three accounts to 15 minutes. However not knowing this caused me to miss important emails.

For the last two weeks I have noticed a marked decrease in the number of emails I am receiving. This is on my X@scratchmitt.com account email provider Gandi. I have attempted to contact Gandi but no response as yet. Is it possible the fault lies within my Thunderbird settings or installation?
