I've been using Thunderbird on a Windows machine for years. I now have an iMac and recently downloaded Thunderbird to start transitioning over. When I try to set up an existing Email address, the configuration is found in the Mozilla ISP database. After I enter the password though (mobile.charter.net), I get an error stating "Unable to log in at server. Probably wrong configuration, username or password". The password is correct and works on the Thunderbird version on the Windows machine. I have multiple Email addresses and I get the same error on all with verified correct passwords. Any help to correctly install would be greatly appreciated!

Hello,

I accept Teams events over the email, but cannot join them because the Join Meeting hyperlink is removed in the event's description. When I try to edit the event's description manually, the Edit option in the event's context menu (right click) is grayed out as can be seen in the attached picture. I also did not find any other way to change the event's description to insert the Teams meeting URL.

How do I fully edit events, including description and event dates? I need to have calendar events based on Teams meeting invitations work out-of-the-box. How do I achieve this?

Note: Exporting an individual calendar event would also help me solve this problem, but I don't think such a feature exists. If there would be, I would have exported the broken event, correct it manually, delete the old one from Thunderbird, open the event with Thunderbird and then add back the corrected version.

Thank you, Razvan Chisa

This version is very slow when opened ... it seaches through for various emails (gmail and Outlook) and snags on something called 'Checking Mail Server Capabilities'. Other issues include a slow copy to the Send folder once an email has been sent. I am not a technical person, been using TBird for many years and until now have really enjoyed its capabilities

Is there a known related issue? Overall the performance is very poor ... I use a series 7 processor and have WiFi speeds in excess of 100 MB.

Thanks Ron

Bonjour, Je reçois des mails d'un même site, certains sont cliquables, d'autres non. Si je les lis avec orange, tout est ok, sauf avec thunderbird. Que dois faire pour continuer avec thunderbird. Merci pour votre aide

Today I agreed to the update of Thunderbird. After the update all my data have been distroyed - no calender data have been shown nor my previouse emails nor my structure of emails worked as ususal. I safed a backup file (zif) from another PC to an external drive. Now it is not possible to import this file because the zip is to big and I get the order to unzip first. If I do this I get a long list of errors and nothing works. Please tell me how to solve the problem! Ralf

My email (bnmalm@att.net) was associated with the Name "Christmas family." Now, when I send an email from bnmalm@att.net it displays "Christmas family" instead of "Bruce Malm" as it should. I cannot fix this.

New laptop. Took it to the Geek Squad to move the data from my wife's old computer to new. They had me sign in to Windows on the new machine and perform the setup steps, then took it and the old computer to do the data transfer. The issue is that the returned new computer had my MS profile on it but my wife's mail under that profile.

To try to correct this, I set up my wife's profile on the new laptop and my thought was to export the email from my MS account's TB data to a public folder, turn off TB and sign off my MS profile, sign back on to my wife's MS profile, start TB and import the zip file in the public folder. However, it tells me the folder is too large and I must unzip and import from the extracted folder. Windows Explorer won't let me unzip the file saying it's not a valid zip file. Ideas?

Thanks!

When I click on an email, instead of just showing the email, it sets up a Reply screen showing From me and To Me. At the bottom there is an alert: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity......" (lists my email user name and address). Im not clicking Reply, I'm just double clicking the message to Read it.

Running Sequoia 15.7.2 on MacBook Air. It just started today. I have turned it off and on, no change.

I want Thunderbird to stop marking everything I delete as having been read. The way it works now, if I accidentally delete mail that I haven't read yet it's much more difficult to find it when everything is marked read even when it wasn't. I searched everywhere and haven't come up with a solution for this. It was reported as a bug years ago and was never fixed.

No longer a Spectrum cable user. Been using Firefox/Tbird for years. Will I still be able to use existing (charter.net/Spectrum) email address via Tbird?

At startup of Thunderbird, get error related to Outlook which I do not use. Get message - "UserHasNoMailboxandNoLicenseAssignedError"

How do I get rid of this error, has been present since last esr release and expected it to go away with new release - did not. Do I have to reinstall Thunderbird to clear.

Why suddenly has Thunderbird stopped logging my messages that I filter manually even though I have logging enabled? It used to work just fine. It no longer logs ANY message filtering. I have not changed any settings. I depend on it especially to confirm that new filters I set are working properly. How can i fix this?

Hi, I have two email accounts configured to Thunderbird. One stopped receiving emails this week. When I open TB, it's asking password for the account.

Then it shows at the screen bottom xxx@yyy.zz: Host contacted, sending login information.

then after a moment, a popup window says

Login to account "xxx@yyy.zz" failed Login to gamma.yyy.zz with username xxx failed.

Sending emails works ok.

Any ideas ? Possibly a corrupted profile ?

Best regards, Jarmo

This morning when I opened Thunderbird it got all my new messages in inbox but when I went to transfer some to local folders there wasn't any. I probably had about 25 folders in there. I still have email on my older computer and it still works fine. Local folders are still there. What do I do?
