As soon as I click on the Thunderbird Icon to start Thunderbird I get a Yahoo Page covering over my Thunderbird page with no practical way to remove the Yahoo page permanently? This is like a scam page or something from a devious hacker?

Using Acronis True Image for Western Digital (ver 2025 build 41936) to backup my files on a daily basis. Recently the backup program has been stopping and reporting that it cannot access some Thunderbird files, even when Thunderbird was not running (1st image) I tried 'Compacting all Folders' in Thunderbird but the result was the same (2nd image). Lastly, I tried clearing the cache - the result is the same. In all cases Thunderbird was not running during the backup.

i realize that this is not a Thunderbird issue, but I've been unable to get help elsewhere. I wondered if anyone might have a solution since Acronis apparently sees the file as being accessed - is there a way to remove that?

Good morning . . . I have recently switched from an old Windows 10 machine to a new macmini, and have switched my Office 365 account over to it. Simply stated, Outlook is not working, and I have no desire to continue with it. Will Thunderbird suit my needs? Will it allow me to import my old contacts and emails, both from my Windows machine and the new MacOutlook?

I made a folder and called it April. One day the folder just disappeared. No one seems to help me recover the folder and i need it. Once I moved emails into that folder they are no longer available in my inbox. SO if you know how to recover my folder help, or if you know how to recover emails that were sent to a folder, that would work also. I use Windows 11 and I have the most recent release of Thunderbird. I use Charter.net as my isp which is pop. Thanks,Charles

importing pgp keys from Thunderbird on Linux to Thunderbird on Windows 11 produces error

On my Linux machine, I exported the public key for an email address in Thunderbird 140.8.0esr (64-bit) into a file. I transferred the file to my Windows 11 machine via Warpinator.

On the Windows machine I am running Thunderbird 148.0.1 (64-bit). In Account settings>End-to-End encryption, I click Add Key>Import an existing OpenPGP key>Select File to import, and then I select the file.

I get an error message: Error! Failed to import file.

I'm surprised. I would think that going from one installation of Thunderbird to another would work this way. I am concerned that I won't be able to read incoming encrypted emails without the key working.

Can someone help me?

Does Thunderbird store emails after you delete the email from Outlook?

I have several MS 365 accounts that I have added to Thunderbird to backup. Now that all the emails and data is in Thunderbird, I would like to deactive the MS 365 accounts completely as the company is closing down. I need to keep the emails as archives for several months in case of an issue, but the MS 365 account will no longer exist. Will Thunderbird delete all the emails once I deactive the 365 accounts or is there a way to store them permanently?

For record, I already tried to add them to my Outlook app on my Windows computer and back up a pst file, but it is not bringing over all the years of data like Thunderbird did. Only recent items.

It now tells me I have a couple thousand files left. however, before the massive delete, it said I was using 15 GB of storage. now, with only 2000 files left, it still says I have 15 GB used. I've tried compacting, but I get an error, saying I do not have enough memory to compact. How to I release all that memory that contains just ghost files?

Hi,

I configured my account using the server's IMAP service. Every time I open Thunderbird, it asks me for the password of the calendar service of that IMAP service. But it doesn't have a calendar service. Even if it has, I don't want to use it.

I looked everywhere in the settings page, but could not find a way to disable it.

Why the app keeps asking me for the calendar service's password and how to disable it?


Thanks.
