Thunderbird Community Forum

After last update can no longer send or receive emails on 1 account. Found they had changed all the settngs to wrong configuration for this account. I corrected the incoming server name and port but can not find the outgoing server name and port to correct that. Where do I find Outgoing server settings so I can get this fixed? Thanks for any and all help.

My Mailstore installation will not connect with Thunderbird, stating that pref.js cannot be found. Linking to Mailstore is required thus: AppData\Roaming\Thunderbird\Profiles\741kq2if.default\prefs.js

By enabling Hidden Files on my Windows 11 pc I can link to 741kq2if.default but not beyond to the pref.js 'file'. Note that my T'bird is fully installed and operational. I would appreciate advice. Ron

As the subject states: Since installing Thunderbird - 128.3.1esr (64-bit) - the app constantly crashes when running but not actively in use on Win11 Pro 23H222631.4317. Crashes do NOT appear to happen when using the app, tho it has crashed when removing duplicates from "local folders" top level, or conduction a "compress". Quite a few of my crash reports have been submitted.

Any ideas as to why?

I'm running Thunderbird 115.15.0 on Ubuntu 24.04. I have a recurring event that was initiating by an outside invitation. If I try to delete a single occurrence, by any means, it always reappears after a while. It disappears from the calendar and from the "Events this month" pane, but reappears after a while or immediately after starting thunderbird. "By any means" includes when the event initiator sends a cancellation notice and the cancellation is accepted, using the delete key from the "events" pane, using the delete key when clicking on the item in the calendar, or right clicking on the item in the calendar and finding one's way to "delete only this occurrence". This is making the calendar almost useless. This is a purely local thunderbird; I've never tried Caldav or whatever.

(On a 2nd matter, why do not of the "topics" for asking a question on this forum relate to my question?)

Hello, my Thunderbird (version 115.3.1 in OS Windows 10) crashes ~10 seconds after I start the software (without report). It also crashes in the safety mode. So I have installed the latest version (128.3.1) but it also crashes after ~10 seconds. There is no crash report. The other software works without problems. To open the profile directory within Thunderbird for reorganize the Thunderbird profile does not solve the problem. From the Windows task manager I get a (great) dump file. So what can I do?

Cannot connect to email through swcp.com. Thunderbird says: No Message Found".. Info from you says Thunderbird crashed (6-7 days ago), will "try" to reconnect when up and running. Do I have to use Thunderbird if I subscribe to swcp? Send answer to JerryKayaa@aol.com.

HI, I have TBird 102.15.1 64Bit installed on several different PCs and laptops. On my main Laptop I checked the Roaming\Thunderbird folder properties and found the following: Size on Disk: 35.8 GB Contains 253,172 files and 1,533 Folders. Is their anyway I can reduce the size? My TBird seems to be running slowly and occasionally stalls. I do not want to switch back to Outlook client program, I am not a Microsoft supporter. I do know I could move mail to local folders but would that mean I could only access them from one machine? Thanks.

This is a continuation of a problem I reported earlier... https://support.mozilla.org/en-US/questions/1442170

Updating to version 115.9 did not solve the problem. Today I updated to 115.10.1 and the problem persists. Thunderbird is also recommending that I update to version 116, but I don't even see that listed on the Mozilla web page for the change logs.

Thunderbird 115.10.1, Mac OS 10.13.6, iMac 20-in Early 2008 model.

I can open Thunderbird and check mail in multiple accounts. If I close the Thunderbird window (but leave the app running), CPU usage will eventually jump up to more than 100%. It does not happen right away, but could take 10 minutes or so. Currently it is at 115% processor usage. If I open the Thunderbird window again, the processor usage drops to under 8%, then drops again to below 0.4%.

The calendar I had before the upgrade to 128.3.0esr (64-bit) worked fine. After the upgrade, when an event was displayed giving the date/time reminder popup everything appeared normal. If I tried to edit the due date/time within the popup everything was normal, and data saved OK. Now the problem, if I clicked on the main calendar tab, the app would go directly to not responding. Same thing if I do "Alt-3". I tried all the different methods to bring up the calendar. All ended as not responding. Does anybody have the same problem?

Hiya, I have two email accounts running on thunderbird. They are set up with imap. They ran perfect, but since about 4-6 weeks their connecting to imap is not or hardly happening. Last week for some reason they connected back and new messages were loaded, but after that moment, no more. I have checked the imap settings on both accounts (one with dds.nl and one with gmail.com) and they are still correct. I have downloaded the latest version of thunderbird, but no improvement. What is going wrong?

Cheers, Bertus
