Thunderbird Community Forum

It's been almost a week now, and my 2 Microsoft email accounts will not connect to Thunderbird anymore. All was fine for years, but something changed that I can't figure out!?! I have gone to my Microsoft email server and checked that my passwords still work. I even updated one and it works on Microsoft server but not Thunderbird's!?!? I even deleted one email account from Thunder bird to re-install it, but when I tried a fresh re-install Thunderbird still won't connect to Microsoft server??? I'm at my wits end, and may abandon Thunderbird completely if someone there doesn't help me connect!!!

Hi,

I would have posted this on this previous question by the same name https://support.mozilla.org/bm/questions/1266115 However it has been closed from further discussion despite being the top search google link for "thunderbird filter contains wildcard"

And what I wanted to say is that

This should long have been core functionality It is not even apparent when you make the filters, that wildcards (*) don't work So you make a ton of filters and they're silently broken !!!

I find the general filter creation process very cumbersome, almost almost every setting has to be changed every time, the main window, locks so you can't copy-paste from it mid-filter-creation and many many other quirks that make each filter creation an annoying 20 steps process, core among which, is the inability to create a destination folder on the fly while creating the filter !

But yeah, no wildcard support is kind of crazy

for example I want to put all emails from pizzahut in a folder

But they randomly change their From URL to @a.pizzahut.ca @b.pizzahut.ca @c.pizzahut.ca @d.pizzahut.ca @e.pizzahut.ca @f.pizzahut.ca

It's like they know the filters can't wildcard ! they is super annoying !!

All of a sudden Thunderbird won't get my incoming emails from att.net (currently.com)

I'm using Thunderbird 152.0a1 (2026-04-22) on Windows 10 64 bit. When I click the "Get Messages" button or File > Get New Messages for > [my e-mail account] nothing happens. The only way I've found to check for messages manually is by closing and re-opening the program.

Hi. I´m running thunderbird 150.0 under win10 an a HP2760p with 8 GB RAM and 155 GB of free SDD-space.

I´ve got the errormessage: "Nachrichten konnten nicht in die Mailbox-Datei geschrieben werden. Stellen Sie sicher, dass das Dateisystem Ihnen Schreibrechte einräumt und genügend Speicherplatz zur Verfügung steht, um die Mailbox zu kopieren."

That is: Unable to write mesages to the mailbox-file. Make shure to have writing rights according to the filesystem and enaugh space is available to copy the mailbox.

I can´t find a limitation to filesize. I deleted a lot of mails, the error persists. I updated from thunderbird 140 to 150.0. The error persists. I downloaded my emails on an win11 Laptop. The download stopped after a while with the same error.

What can I do ? Thanks in advance - Robin

I subscribe to a number of RSS feeds in TB. This works well nearly all of the time but sometimes I find that TB has paused updates. I never want it to do this.

Why does it happen and is there a way to stop it doing it?

Thunder bird version 140.10.Oesr on iMac desktop. Just stopped DL mail. Asked me to sign in; shows my user name. When I click NEXT it goes to a blank page and say "too many trys" Next dy; say on first attmpt.

I am with activ8.net.au, and I cannot now send e-mails. Receiving is fine. Have contacted activ8-me and they cannot help.

Version is 150.0 (64 bit)

Program does not check Pop Mail accounts on startup. Only checking after triggering with button or shift+f5 Timely check is succesfull (1min,10min etc.)

I got 6 accounts and -everyone is checked to include on startup -added/checked config file options;added new lines -tried safe mode etc. -delete json file

None of the above worked.

Any more suggestions?

Kindest Regards

I can't get email. When I try a window comes up saying sign in and when I click on it the next window says error 400 and that's it. I can't get my email! Please help!

It's been several days and no email!!

Pop-up with Thunderbird icon: "Enter credentials ... on imap.mail.yahoo.com". I have spent many hours and only made things worse. I can still access mail via webmail, but not via Thunderbird.

Hi,

I have a Shaw.ca email account. The outbound email does not work for this account.

The outbound email works fine, it is just the inbound server that refuses access.

Hello, and thanks for the read...

ISSUE: Every day I have to call the telecom ROGERS that took over for telecom SHAW, turn IMAP and Pop3 on 9 Email accounts (they lost 1). Sometimes the 1 to 2 hors chat w/ a human turned it back on will not last long.

DETAILS:

1. I can receive outside Emails *because I can't send using Shaw/Rogers, checking for Email, just hangs at trying to login in to any of the 9/10 emails.
2. When I can get a support person to check, they tell me that IMAP and POP3 are turned off.
3. They will tell me they re-enabled it. But it doesn't enable for me.
4. It all works OK when using the online webmail Zimbra. However, I need to check 3 of the 9 email accounts every hour, others every 6 hours, and others once a day at boot.

QUESTION: When using POP3, does the setting on my SMTP need a special setting on Thunderbird?.

NOTE: I am complying with "Rogers With Shaw" passing the buck to the Email Client (Thunderbird) by asking here - "Could It Be The Email Client'! And my answer is 'No', because Thunderbird works perfectly with 54 other Email accounts.

Thank for reading this, and for any input you may add, ~r

P.S., I'd like to see a upgrade to this input form that allows us to Preview out Post And, when I started this Post, it alerady had a image from a previous Post

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: * OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE NAMESPACE LITERAL+ AUTH=PLAIN AUTH=LOGIN] Dovecot ready..
