What do I do about this warning I am receiving when I refresh my inbox? "The certificate for pop.windstream.net is not valid. Someone could be trying to impersonate the server and you should not continue"

   Unable to receive new messages on my Thunderbird inbox for this warning

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...

TB is hanging on startup as it cannot connect to an IMAP server (Ping times out) I am chasing this separately. If I click on the TB window it grays out and I have to shut TB. I know which account is causing the problem but how can I start TB WITHOUT it trying to access servers so I can delete the problem account?? Thanks in advance. Paul N

I am transferring thunderbird to a new computer. I copied the Thunderbird profile from the old computer to the new computer but most of the old messages are not showing up. I uninstalled thunderbird from the new computer and reinstalled it and again copied the old profile but still the old messages are not there. How can I get them on the new computer?

Hi everybody, after switching from microsoft ews to graph using exchange server any response on a e-mail is starting at the bottom. I would like to have my response editor on top above the attached e-mail I am responding to. All other e-mail accounts are working this way but not on the Microsoft Graph e-mail account. Could someone please help ? Regards Thomas

Thunderbird 158.0. (64bit)

I'm not sure what to call the different parts of the compose-message window, so please look at the attached screenshot. I'd like to relocate some of the buttons from the top right corner to the lower left, below where the formatting buttons are. Is there a way to do so?

Hi, I am running a windows 10 with Thunderbird version 157.0.1 (64bit) IMAP version. I am having problems with quite a few of my old messages not wanting to open when I click on them. This is the message that pops up (Server mail.daystar.io has disconnected. The server may have gone down or there may be a network problem.) mail.daystar.io is my carrier.

My Thunderbird connected to my gmail is running slow. Thunderbird is not running slow on my other (non-gmail) account. It takes 10-15 seconds for an e-mail (from gmail) to be deleted or moved within Thunderbird. I have tried "compacting folders" and "repairing folders" and that does not help. Please help!

I disconnected a Google Workspace account - Calendar and mail - from a former workplace. As far as I can tell, it's been deleted from Thunderbird.

However, I'll still get dialog boxes and an occasional browser popup asking me to reauthorise it.

How do I get rid of it once and for all?

This morning I started getting this popup in lower right part of my screen every minute :

Mozilla ESR Thunderbird Connection to server inbound.att.net has been reset

It continues over and over as TB tries to get new messages.

Also, AVG Free antivirus is telling me it has identified a site certification problem. LOCATION: inbound.att.net (POP) Process: thunderbird.exe Detected by: Email Shield

In TB Help it says I'm currently on the esr uipdate channel .....whatever that means Whats the issue here? Can anyone help?

Thunderbird (157.0.1 (64-bit)) write toolbar missing.

All things are correctly configured, as mentioned in this article, and nothing is working in making the Write (Compose) Formatting toolbar appear again.

Everything is set to compose in HTML format and the keyboard commands mentioned in other articles and so forth do nothing.

Is is perhaps a corrupted profile setting file somewhere? Is there a Config Editor setting that needs to/can be changed ?

Please advise, soonest, thank you in advance.

Attaching files no longer works in the current version of Thunderbird—what should I do now?

Das anhängen von Dateien in der aktuellen Thunderbird-Version funktioniert nicht mehr, und nun?

Since the recent update, 157.1, I cannot get the "Get Messages" button to work and it will not download new emails. I can download a previous version and it works just fine. I also cannot stop the auto updating function even though I check the box to not auto install.

My gmail account in Thunderbird stopped working on my lap top but is is still working on my phone and note pad. This happens from time to time so I usually just delete the account in Settings then Account settings then just add it as a new account. But having deleted the account I now can't add it back again. It doesn't allow me to add the account. At the Incomming Server settings Error Creating Account Incoming server already exists

Hello at all, I manage several email addresses through Thunderbird Version 153.4.Oesr (64-Bit). For a few days now, it has not been possible to send emails with attachments. When I click the attachment button, nothing happens. Does anyone have an idea what might be causing this. Thanks for your support :-)
