Hi Everyone!

I am currently on Thunderbird 115.10.1 (64-bit) and for a few days now, I can't open the calendar tab. The "Today Pane" is working and showing events though.

When going to "View" the items "Calendar" and "Tasks" are greyed out though.

Any idea on how to get the calendar back? The company will move us all to Exchange and Outlook soon, so I thought I might "survive", but it is pretty impractical have to open my calendars separately in the browser. You only notice how often you use something, when you don't have it. ;-)

Hey all!

I recently migrated my hosting and I deleted the accounts on my Thunderbird client to set the new ones with the correct new Hosting.

The accounts are working correctly, but everytime I open Thunderbird, it shows me a login request from the old hosting service (which by the way, there is nothing there anymore, i deleted all the accounts and data).

I already uninstalled and reinstalled mozilla and tried to "fresh start" again, but this problem doesn't seem to go away.

Help is much appreciated!

I want to change the line spacing in my emails to single line including paragraph spacing. Advice given in previous posts says to select Menu then Options. I have clicked on the 3 bar Menu icon and Options is not there. I clicked on Tools in the Menu Bar and Options is not there either. I apparently have to get to Composition, but cannot find a way of getting there.

Using Thunderbird on Linux I cannot delete any local folders, when I try to delete them I get more copies of the folders on reopening Thunderbird, after the system says it is "not responding" and I close it down. I have tried several times and now have multiple copies of the local folders I've tried to delete.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX. Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.

I have had Thunderbird email account for years and now I have problems getting my emails to come through on a regular basis. I have to shut down my PC and then restart to get emails to come through. What is the problem. Thanks, James Craig Herring

I have a Fastmail and 2 Cox addresses on rolled back Thunderbird 102. The Fastmail is IMap and both Cox addresses are POP 3. Cox is transitioning to Yahoo Mail, but we have kept our Cox addresses. I'm getting Yahoo mail web mail and think I should change the existing settings on Thunderbird and not create new accounts, but want to make sure. I saw something about Thunderbird and Yahoo and want to make sure I do it right or should use the third party setting for desktop clients that Cox provided for the transition. For me, the transition has not gone smoothly and I'm pretty frustrated. I am not a techie and any help in getting mail to the 2 Cox addresses landing in Thunderbird and the Fastmail continuing as is would be greatly appreciated. Thank you.

I've gone into "sort-by" and tried enabling threading. I've tried checking the unthreaded box. Group job related email still just disappears. I can't find received group email in the trash or in the junk. I can't find any evidence in Thunderbird that the group email was received. If I go to a different email tool, there it is. Thunderbird is broken. If I scroll back in time and accidentally scroll past the date of the first group email, there it is. I can't be spending all day scrolling through months to years worth of email just to find out I got a group email from someone today. This is totally unreliable way to find an urgent work email.

I'm setting up TB for the first time with multiple email and calendar accounts. Some are gmail / google, and others o365.

The primary TB account's calendar doesn't seem to be syncing fully. It's an o365. account. But the email is working.

I added an event on my Outlook for Android on my phone. Its appearing in OWA, and in New Outlook on my computer (so it did sync from mobile Android device to server, and from server to my New Outlook on the Windows desktop). But its not appearing in TB.

Not sure what to check or what the issue might be.

Also, I'd love to replace Outlook Android on my mobile with what I think is K-9. But can't get the same account referenced here to connect to the outbound server.

Welcome any help, and appreciate you all doing this collaborative work.

I just installed Thunderbird (working elsewhere) on a Windows 11 machine, and used the 'auto setup' feature. Sending/receiving works fine, but for every message sent:

1. A pop-up appears, which reads 'Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message to Local Folders/Sent-mydomain.com

2. The current command did not succeed. The mail server for account mydomain.com responded [TRYCREATE] Folder doesn't exist. (Failure).

Sent messages appear just fine locally in Thunderbird, and also on Gmail, and they send fine as well, so I just need to disable the incorrect error messages. Thanks for any help (NOOB level tech savvy).

Hello, I have Webmail by Godday. I have been using Thunderbird for many years to connect to my accounts without issue. Past couple days I get an error message saying it can't connect to the server. Godaddy says they haven't changed anything. I can log in on Webmail but not with Thunderbird. Thunderbird brings up my mail from before it couldn't log in so I have all my stuff I have saved but I can't get new mail or send mail. I deleted Cache, restarted and all that... Disabled add-ons in trouble shooting mode. Here is what I got. Much appreciated

Along with most of the world, I hate threads. My normal practice is to keep only the last email in a thread quoting all the contributions, and to delete the rest. Then I have one email with everything about that in it, with a history trail. I've done this for years and years. Then, some time last year, after an update of Thunderbird, everything was in threads. Someone replies to my message, and the thread goes missing from Sent, and appears in Inbox, but not marked as unread - you only see this when you expand the thread. If you reply, it jumps back into Sent. Finding anything is now a time-consuming nightmare. But there also appears to be at least one bug.

Suppose I now go into a thread and delete an intervening email. Thunderbird clears the preview panel of emails. If I click on Sent then back in Inbox, they reappear! But if I'm now confused as to exactly what that delete did to how many emails, I click Edit / Undo Delete. What it seemed to do tonight when I hit the Delete was get rid of a big chunk of the large thread, including some emails I hadn't read yet, and some not in this or other threads! They are not in the Deleted folder - they are gone! I think it has also done this before. What a mess! As for evidence, reproducing it is not something I want to do.

Since I updated to the last Thunderbird version, the messages in my inbox are deleted after one month if I don't "star" them. I don't think I changed any settings? Can somebody help me with this?

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks
