Can't get rid of this spam: ecare.all.r@emailff.att-mail.com Unfortunately I clicked on it and multiple spam sites came up. I've tried the spam filter and it doesn't work. Suggestions?

Hi there, I have several email accounts I use Tbird to manage. One of those is a hotmail account. I have the settings setup correctly for IMAP synchronization. But, after the initial pull of messages, the connection to the server seems to fail? For example, I open tbird, it pulls in new messages, run filters, etc... If I come back and try to reply to a message, the outgoing server will timeout (if you test the outgoing server in settings, it connects. If you reply as soon as you open tbird, it will send a message from that outlook account). I believe this issue is more than just the outgoing server. For example, if I move an email to a different folder, it won't register the move until I reopen tbird? Similarly, sometimes if I try to open a message after tbird has been running for a while, the message will not open/fail to load.

These issues seem to be impacting only this outlook account. I'm really not sure where to go with troubleshooting and looking for guidance.

much thanks, Ryan

When I installed Thunderbird, I selected Custom Installation, thinking I would get an opportunity to select which components I wanted installed. All it allowed me to do is define the installation folder. Not very "customizable." Anyway, I already have a calendar app that I'm perfectly happy with, don't need a task manager, and don't use chat, Is there a way to remove those apps from Thunderbird?

Downloaded Thunderbird update and program now opens to Xfinity but no updated emails... Can I remove and re-install it without losing all my previous emails and contacts? Or is there any better fix?

• NOTE* It's Version 158.0...

How do I set up Thunderbird so that no incoming email is automatically diverted to my spam folder?

I like TB flagging incoming emails that it thinks is spam, but I don't want TB to automatically divert any emails into the Spam folder. Is this possible?

I use four email accounts on TB. I'd like to set this up for all four accounts.

I am having problems sending email form my account, [redacted]@smartpointproducts.ca. I login successfully and the program responds saying the account has been successfully registered however, it still refuses to send emails from this account.

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

I have no problem receiving emails on this account [redacted]@smartpointproducts.ca however sending or replying doesn't work it's not the passwords here's my SMTP server settings screenshot below.

I have my Google Calendar added through the network/gmail account process. I can see the events from my Google cal in TBird. When I accept an invite that came into my email in TB, it gets added to the TB calendar but never syncs back to my Google cal. Looking at the Error Console, I keep getting "Server Replied with 500"' errors (full error code is below).

I already tried all the online steps - delete/add calendar, clear password, reset OAuth token, still get the same issue.

calendar: [calCachedCalendar] Unable to perform playback action add to the server, will try again next time (longnumbersequence,[Exception...

I'm running Thunderbird 157 64bit for Google email, Calendar & Tasks. This has worked nicely for months even after the upgrade to 157. Today Calendar & Tasks fail to connect and are completely blank. Apparently the Add-on 128.5.12 (Philipp Kewisch) that made this work has been disabled for some reason. Please don't tell me that Thunderbird has suddenly decided Google Calendar and Tasks just aren't needed by anyone anymore. There is no new connector available that I can find, just a suggestion to go back to an older version of Thunderbird? Please help me understand. Thanks!

I've received the following message the last few days when I send an email with Thunderbird:

Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. (I am sure neither of those errors apply.)

It then gave me the option to "save" (I didn't get the exact wording before I clicked on "save") and I don't see it anywhere. This was a very important email and I need to find it.

Was kann ich tun? Habe Probleme mit mozilla. Bei derAuführung der Programme Thunderbird ( ständig ) und Firefox ( manchmal ) kommt es zu Abstürzen wie Programm keine Rückmeldung, einfrieren so das keine Eingaben mehr möglich sind und ich jedesmal das Programm schließen und neu starten muß.

It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

I understand Thunderbolt AI is available. Can I use it as an ordinary Thundermail user to ash questions just like I would ask a question of ChatGPT etc? If so, how do I install (Windows 11, Android) and get started?
