Starting yesterday 4-3-2025 my Thunderbird email keeps locking up and saying it is not responding. I can close it and open it and then work with it for 2 or 3 minutes and it will start not responding again. This is a consistent problem the last few days. I did check and it said there was an automatic update on 4-2-25. I am not sure if this had anything to do with it but i did go in and request an update about 2 hours ago today. This has not helped as I still consistentaly get the not responding problem. Please advise what I can do to fix this.]

I have tried to add this address to my address book. Normally, one clicks on the icon and a pop-up appears to modify information and confirm entry into address book. This address always shows up as "not in book," clicking has no apparent effect, until one checks the address book and now duplicates exist.

First image you can see that Freeman is in the address book Second image you can see that Tbird thinks the address is not in the book Third image after I've clicked and no apparent action is taken, a duplicate appears.

When this bug first appeared I had clicked on the icon multiple times, and multiple entries appeared in address book. I deleted them all, tried again, bug still happens.

I went to use Thunderbird mail on my laptop for the first time in ages. I can receive emails but they won't send:

Log in to server SMTP-mail.outlook.com with username x failed Retry - Enter New Password - Cancel

- I entered the current password, which works fine for Thunderbird Mail on my desktop PC, and checked the box use password manager.

Send Message Error: Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp-mail.outlook.com Please check the password and verify the 'Authentication method' in Account Settings | Outgoing server (SMTP)

Server Type: IMAP Mail Server Server Name: imap-mail.outlook.com I CHANGED THIS to outlook.office365.com - to match the server settings on Thunderbird Mail for my desktop PC - and restarted Thunderbird, but the Log in to server failed message displayed again. Port: 993 Default: 993 Connection security: SSL/TLS Authentication method: OAuth2

I trust I have provided sufficient information for you help me. Thank you!

In Windows 11, Thunderbird 140, how do I increase the font size in new events box?

- I have tried to make the changes in Windows 11 settings (text size) and this has not helped. - I never had this problem in the past when using Windows 10.

I have "Googled" this problem and had no results.

Kind regards: Gary Shaw

I used to use these add-ons

Old Icon Phoenity Buttons Phoenity Icons

to make Thunderbird more attractive, but now I'm having constant problems. The interface has become schizophrenic, and every time I open it, the icons have a different style, so I've been forced to disable the add-ons.

The question is, are there any supported add-ons left? I can't find any on the website. :(

I can't receive or send e-mails. The software asks for a password for pop.orange and none of the passwords I have works. I am thus in a no-man's-land. Perforce, I use the Orange e-mail client, which hasn't the capabilities of the Thunderbird client. . The other facilities - addresses, calendar, all work.

I shall be grateful if you would please direct me to a fail-safe solution enabling me to arbitrarily impose a password which I can generate using Norton password manager, and once again receive and send e-mails?

when I try to run Thunderbird it opens with my folders but the comes up with the message "Login to server imap.gmail.com with username scoteng1961@gmail.com failed." I exported my details then used the thunderbird uninstall program. then reinstalled it. but problem persists. What password is it asking for and how can I get a reminder of it or a chance to change it?

I'm currently on Office Outlook 2021......something happened and the license became invalid....according to Msoft.....I will have to re-purchase.......bought if it at huge discount on ebay so should have expected this... I'm investigating moving to Tbird.....but I have some questions.... 1. The importation of PST file seems rather complicated....is there an easy way to do this...??? 2. In Outlook I use the email....calendar....and notes.....I have a lot of notes as this is how I keep track of what I do for my clients......If somehow I import my PST file into Tbird....does all the email...calendar and notes come with it or just emails...??? 3. I POP Gmail into Outlook....but Gmail requires an App Password......can Tbird handle this..??? 4. My current PST file is about 3gb in size....Can Tbird handle this large amount of data..???

Thanks in advance for any assistance the community can offer... Steve

Tbird starts to d/l messages: "nn of mm new messages" counts up and just before it gets to the last few, it stops. It doesn't put the retrieved messages in the inbox or anything. Then it gives this error message:

"The DELE command did not succeed. Error marking a message as deleted. Mail server pop.mail.yahoo.com responded: Too many requests."

But this is POP mail, so delete request don't go back to the mail server. The number of emails deleted from the local db shouldn't have any effect on d/l... I'm mightily confused.

Yes, I did delete thousands of old emails. Still shouldn't make any difference for retrieving mail, nor should the client be overwhelmed by commands it successfully executed days ago.

Failure to download email from Optus. I have spent a number oif hours to no avail talking and typing with the Optus staff regarding this problem. 1. I can send email from TB but cannot receive. 2. I can see the incoming emails in their Webmail site. 3. Optus confirm my settings are correct for both the mail server and SMTP server. When I go to Settings> Security > Passwords > remove server so I can re-submit my password, the only one showing is the SMTP server. Should the incoming mail server also be shown?

I am frustrated and ready to dump TB but have bee with it many years and don't want to start again with another programme as I am 83 and am partially blind. Please can anyone assist?
