Thunderbird Support Forum

I've been using Thunderbird for a very long time now but I've never experienced this kind of problem: I have few outlook.com accounts set up and looks like I can't send emails from outlook.com using Thunderbird. To send a new email or respond to my emails I have to manually log in to my outlook website account or use my phone (Android). Every time I try to send or respond to email the Thunderbird I get these messages (included in the attachments): no connection to the server or it keeps asking me to put my password even though passwords has not changed. There seem to be no problem with receiving emails.

Hi folks! I use Thunderbird Beta (128.0b1 (64-bit)) for my email currently. I've been having a problem with some emails, mainly in my Sent folder, showing up as long strings when I try to view them. It looks like untranslated code put into plain text to me, but I'm not sure what would be causing it. I have no problem reading the email if I log into our webmail to do so. Example text from an email attached. Is this a known problem? Any ideas on how I might solve it? I like Thunderbird, but not being able to search and read through sent emails is a real problem. Thanks!

I have deleted 4 years of emails and yet you now say my mail box is 85% full. How can that be. What do I do to change this ? I need to maintain a system of emails and contacts for years at a time

I added a second IMAP profile on thunderbird and i keep getting the message 93% memory used. I understand he maximum capacity should be 4 GB, but when i checked, the first profile had 3.5 GB full, and the second only 1 GB. Is it because i added the second one and thunderbird split the memory capacity? I removed the first acount and stil the second one has only 1 GB memory. i need the emails received and cannot delete anymore messages, I am afraid it reaches full memory capacity and will not be able to receive emails. Please advise

With the moving of Cox emails to Yahoo would it be feasible for Thunderbird to put an instruction list(with screenshots) of how to get all our TB email accounts from Cox to TB? Do we have to delete all our TB email accounts and re-enter them into TB under the new Yahoo or can we just change the server settings on the existing Cox settings? If just changing server settings what are the settings for the new yahoo? All my accounts are IMAP so if instructions could be made, maybe one for IMAP and one for POP for those who use either. Thank you

I have been running Thunderbird Beta for a while and recently when I go in I get an error that it cannot compress folder because not enough disk space. I have > 90gb available. How do I resolve this?

Yesterday I was hit with what I understand is a mail or spam bomb in my work email. From 5am to 10am i received 1,400 emails from all random sites. Today i already received 200 emails. This is very stressful searching through these to find actual legit emails from my customers. Speaking to one of my employees this happened to they said they had to close their account and open a new one because the emails never stopped coming. I have had this email for 17 years and it's associated with many business accounts and website contacts so it's not feasible for me to change emails. Is there a way to filter these directly to the junk or spam folder so they don't hit my inbox? Or something else you can recommend to block these? please help

My service provider is QX.net which uses Magic Mail web email. I have Firefox 115.ll, 64 bit. I have Thunderbird 115.11.1, 32 bit.

The Magic Mail on my Server shows 253 unread messages. I have identified some of those 253 messages in my Thunderbird folder and they have been read, and are shown as read in Thunderbird. There seem to be 3 different dates involved. This is a concern as it is unacceptable not to receive all of my messages.

Please advise what I can do to address this so that I receive all my messages and so that when I have read them they are shown as "read" in Thunderbird and in Magic Mail.

Thank you so very much for any help.

I'm a keyboard only / screen reader user. I have been using thunderbird for a week and love it. I use the portable version. Anyway, is there a way to rearrange my email accounts without dragging? when I add an account I want it to not appear at the bottom of the list. could there be a way to rearrange said accounts either with a keyboard, or via a setting to move up and down the account via buttons and have it take effect in the tree view? I've been looking for such a solution for a while now. If not, might there be an add on I can use which can aid in doing this? thanks.

This just started. 115.11.1 (64-bit)

I cannot select multiple messages in any folder and move them to any other folder/ Filters will not work either.

As an example, I select 3 messages if my inbox and try to drag them to trash

I get an error popup that says "The messages could not be moved or copied to folder 'Trash on Local Folders' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then choose Compact Folders, and then try again."

Trash folder had been compacted and emptied.

Thanks for any help.

I have been a Firefox and Thunderbird Beta user for decades and all is well until I installed the latest Thunderbird 127 (Beta) It's suppose to be a Final release. Now I get a large ad/notice, informing me to use this version at my own risk and to download the older, stable release.

See attached image. The add takes up a large amount of space on the email client and is very annoying.

How do I get rid of it, never to see it, again?

Thank you and regards,

I do not have an account that I wish to migrate within Thunderbird but I just need to use it to view some .msg files. Each time I try to open a .msg file to view it, I am asked to log in to Thunderbird. Is there any way of just viewing the messages without requiring an associated email account? The messages relate to an investigation I am conducting and I do not own the recipient's account.

My email inbox is really a task list. I find that I email myself items that I need to work on so that they are in the inbox. It's a tiny thing, but it would be so much more convenient to be able to view/edit the task list alongside the email inbox. I organize my emails with the listing of emails full-height on the screen with the preview window to the right of that. I would like to be able to see the Task List to the right of the preview pane. At this point, it appears that only the Today pane can be shown there. This requested feature is supported in Outlook, but the Outlook "task list" is not as nice as Thunderbird's because their "tasks" are just emails that have been flagged - not very useful. Thanks for your consideration.

Company uses office 365, I have my Thunderbird. Since a couple of weeks sync issues appear (i.e.: TB has no right to delete folders in office 365). Finding a solution took several hours in various forums - nothing helps. - the only suggestion I didn'T try so far is asking the office365 helpdesk.

Problem description: When I delete folders they reappear at the old position. empting the trash yields also reappearance in trash. Same for moving folders - a copy is made, but at the old position and empty folder remains. They are gray - so hidden folders. Overwriting obviously does not work, as the folder already exist, but is not accessible. subscribing/unsubscribing does not work. In office365 the folders do not occur. If I create a folder in office 365 (web, outlook) it appears in TB. When I delete it in office 365 (web, outlook) it disappears in office 365 (web, outlook) but reamains - in gray - in TB. By now, the number of gray empty undeleteable folders has grown significantly. Only solution I got sofar is to switch from TB to outlook. :/
