Thunderbird Support Forum

Hi, As the title suggests, I am unable to delete emails from my work Microsoft account.

On attempting to delete an email, the following message is displayed:

"The current operation on "Inbox" did not succeed. The mail server for account [email] responded: [TRYCREATE] The destination mailbox could not be found."

Checking the account settings, it seems Thunderbird cannot see the "Deleted Items" folder (it only shows Inbox and Drafts). I have attached images to show what I mean, comparing with a personal Microsoft/Outlook account where it sends deleted email to the correct place.

Using the latest Thunderbird version that is available on the Microsoft Store version on Windows 11. (115.9.0) I have tried removing and re-adding the account yet the problem persists. Any troubleshooting ideas welcome!

This is a recent change, and in fact I don't *think* there's a "missing message" problem after reading and watching for a couple of days. I *think* something has changed and Thunderbird reports having "downloaded x messages" even if it *just downloaded them a moment ago*.

So it may download 5 messages, then a few seconds later you hit the Get Messages button, and there are no actual new messages but it still reports "5 messages downloaded" but nothing new is shown. As of last week, it would have reported "there are no new messages" when you hit that button soon after having received messages.

So I think:

• there is no serious messages-missing problem
• there is a disconcerting issue with a change in how Thunderbird reports status where a message arrival state is "sticky" and for some duration after getting new messages it will re-report the count of the last receipt when asked to download when there are no new messages.

I could be wrong about either of these, but there's a definite change in a behavior that I'd gotten very accustomed to. It is alarming to hit the button, see a message regarding some number of new messages, and receive none.

I'm guessing others, like me, spent some time panicking, searching forums, repairing the inbox... I think I'm as interested in confirming that there isn't a bigger problem as I am in getting back to the accustomed behavior.

Hope this is useful; thanks for your attention!

Currently on 115.11.0 (64-bit) on Windows 11; first occurred at least one version prior.

How can I get back to being able to search for an old calendar event of up to 2 years ago, now that a recent Thunderbird update removed that ability and replaced it with the 7 search periods option box to the left of the 'contain' search window?

"Unable to connect to IMAP server. You may have exceeded the maximum number of connections to this server. If so, use the Advanced IMAP Server Settings dialog to reduce the number of cached connections." I do not have that option under Advanced Server Settings. I'm using POP3 mail server with Optusnet.

If I deleted an email or moved it to another folder - on my apple app for any of the accounts that I also have on thunderbird

The changes would sync seamlessly - a few seconds after I deleted or moved an email on my apple iPhone mail app - on my laptop - thunderbird would show the same changes.

The same worked the other way if I deleted or moved an email on thunderbird on my laptop - my iPhone would show the changes in seconds.

However now if I do the same on my iPhone The changes do not show up at all.

BUT if I do the changes on my laptop - they will show on my iPhone. It just doesn’t work if I do the changes on my iPhone.

Is there a reason for this?

I have set up PGP with the following guide: https://support.mozilla.org/en-US/kb/openpgp-thunderbird-howto-and-faq#thunderbird:linux:tb115

Under test set up it says I only have to ensure that the from: email is correct.

But what if I use a different reply-to email address?

for example:

• Person A has a PGP is set up for PrsA@example.com, they also publish their public key in https://keys.openpgp.org/, Their reply-to email is PersonA-lastname@example.com
• Person A sends email with PGP public key attached to Person B. Person A already has Person B's public key.
• Person B receives the public key and saves the cert in relation to PersonA-lastname@example.com just to be sure they go to https://keys.openpgp.org/ to check but it is not there.
• Person B sends an encrypted email to their only known address (personA-lastname@example.com) with the encryption public key provided.
• Would Person A be able to receive the email?

tests I have done:

• I tried this with edward-en@fsf.org and I get an email back saying: Diagnostic-Code: smtp; 550 Edward needs reply-to or from to be the same as envelope from
• I tried this to myself and I am able to read the email.

Hello,

I have a strange issue that i didnt find a solution for online. I have made a few new folder and message filters for them. I dont get number notification in taskbar for mails that go in the new folder while the notifications for mails that go in the inbox work just fine.

I am really getting tired of TBird resetting my all my default preferences whenever there is an update. One more time and, contributor or not, I'll abandon the app. I've lost critical emails in the past. This time it's reverted my Threads setting and there seems to be no way to get rid of these damned thread filings. I don't want threads. They make no sense for me and my correspondences get lost as they are buried deeper and deeper into the ooze of Thread world. Can somebody tell me how to turn these things off? And can somebody please, please, please tell Mozilla to stop screwing with my settings when they update!? And don't tell me they don't because we all know that they do.

When I view emails with photos attached inline (both in preview pane and fully opened) i can't see the images as they are massive and go way off the screen. Is there a setting to provide some kind of sensible default so the images are sized within the email i am looking at, so i can view them without downloading and opening in a photo viewer? thanks

I’m running Supernova 115.11.0 (32-bit) on a Windows 7 desktop (64-bit), and – from the beginning – it has been freezing at least once every 24 hours. The only way to “unfreeze” it is to use Task Manager to close Thunderbird, and then reboot it. No troubleshooting reports are ever shown.

Is this a wide-spread issue, that may be addressed in updates?

I have an email conversation that's gone back and forth many times, with the other party including useful links for me. I noticed today that links are only live (blue, clickable) in the most recent email, if I scroll down to past emails in the chain, all links are plain text and not clickable. How can I make them all clickable please?
