Thunderbird Support Forum

Account setup fails with "Incoming server already exists" error. This seems to be the case when the hostname of the incoming server and the outgoing server are the same. My domain is mail.(domain.com) , so imap and smtp are not separate domains.

I accidently powered off system (PC with Windows 10) without closing programs, including Thunderbird. After restarting the system and opening Thunderbird, TB crashed. I have tried numerous fixes:

• Installed the latest version of TB (from 78.11.0 to 102.8.0)
• Opening TB in Safe Mode (disabling all add-ons, reset toolbars & controls)
• Uninstall & reinstall TB

All result in the Crash Reporter dialog, with Report Contents. I can supply the report contents. (It wasn't obvious how to attach to this forum post.)

One KB item (https://support.mozilla.org/en-US/questions/1337785) suggested that the issue may have to do with session.json file. Based on the file timestamp, that seems likely. But I don't know how to edit this file to fix the problem.

I also created a new TB profile, with does not crash on startup, but I cannot get email properly configured.

I have hundreds (maybe 1000s) of email stored in TB that I cannot access.

I would greatly appreciate any help!

Hi

I used MailMerge to create a few hundred emails and put them in my OUTBOX. Now I cannot send them, and when I go to FILE the SEND UNSENT MESSAGES tab is grayed out.

I could do the mail merge again and place the merged emails elsewhere, if need be.

thanks

Hi, I have been using Thunderbird for years. I have always used POP3. Recently I have run into a problem. I can receive emails from my Gmail accounts but I can no longer send emails. It just freezes and shows a “sending message” box. I have checked and checked on the settings and OAuth2 is set and I am out of ideas. Thunderbird works fine for other accounts, (GMX)

oauth://accounts.google.com (https://mail.google.com/ …) entries are in the password listing for all accounts.

So, I removed one the Gmail accounts and reinstalled it. I was asked to confirm that I want to allow Thunderbird to access the account and I agreed. Now THAT one works. I knew the account works because I set it up an a Portable Thunderbird first and it worked.

Is there an easier way? I have EIGHT Gmail accounts an others that use OAuth2. (13)

Also, I noticed that after I removed that account, the “pop.gmail-9.com” was still in the Mail folder. A new “pop.gmail-16.com” was created after the account was reinstalled. As a matter of fact, there are several “pop.gmail-?#.com” entries for accounts that were removed years ago. Can I delete them? Should I?

Thank you. Joe

I'm getting warning icon on my ISP hosted CalDAV calendars (see attached) and even my gmail calendar doesn't sync.

TB will not let me sched new CalDAV events returning "An error occurred when writing to the calendar Calendar of rich@richosman.com! Please see below for more information." and Error Code "MODIFICATION FAILED"

Gcal sync fails silently, but TB scheduled events never show on gcal, and recent gcal entries never show in TB.

My ios device has no problems with either set of calendars using the same network connection.

This has all been stable for several years.

When thunderbird launches, directories "Desktop" and "Downloads" are created in my user home directory. I cannot find in settings how to disable this. The save location for attachments is set to ~/downloads.

thunderbird 102.8.0-2 on 6.2.2-arch1-1 x86_64

Spell check not longer seems to check spelling, and always pops the check window up when must be manually closed. clicking "recheck text" seems to have no effect.

I'm running version 102.8.0 (32-bit) on Win10

When downloading messages from my yahoo mail account the will not load correctly and display the error message "a unique identity matching FROM address is not found" This has only happened since the last update and the messages are apearing as though from my BT connect account and I cannot open them. My BT account works fine and I can download the yahoo mail to my tablet which uses Outlook and I can access the Yahoo mail via my on-line account. I have tried clearing cache and running in compatability mode with no joy. I have had problems with updates before and have lost all my e-mails so am reluctant to try loading a new version.

I find it interesting that after criticizing Mozilla Thunderbird on Twitter, the very next day my laptop seized up and required 2 restarts, then Thunderbird lost three new emails on one email account and started downloading 940 old messages from my Network Solutions mail server. That is some vicious, partisan push-back. Are you all based in Russia? I feel so blessed that religious certitude no longer requires that we heretics be burned at the stake.

If I remember correctly, I opened an account with Network Solutions in about 1998 for aquarien.com. In all that time, I've had few problems with NS, and trust it. A few months ago, I transferred my e-mail accounts with Wild West Domains LLC to NS to avoid the switch at WWD to Microsoft Outlook. But my e-mail for aquarien.com has always been with NS. And since about then, TB has been harassing me every third or so sign-on with certificate errors claiming that NS is not a "legitimate ... site" which provides "invalid information", demanding that I "(checkmark) Permanently store this exception" to "Confirm Security Exception". But no matter how many times I tell it to do so, TB keeps harassing me. It refuses to keep its word about "Permanently" storing "this exception". I'm a retired senior living in HUD retirement housing, who aged out of Social Security Disability Insurance at about 65 onto regular SS income. I don't know about certificates and care less. I trust NS, one of the oldest hosting services, to do the right thing. When I raised this issue before (https://support.mozilla.org/en-US/questions/1397223), I got two guys snarking and talking down to me, addressing not my problem with storing the exception "Permanently", but harping on the "cheap" NS certificates and demanding in so many words that I serve their interests. It's as ethical and appropriate as parents using their kids to fight each other. KNOCK IT OFF Settle any disputes you have with Network Solutions like real adults, Permanently store this exception, and leave me out of it.

Thunderbird is horrible slow in accessing the imap server next door. The debugger shows messages "Message not found in Gloda". What is this supposed to mean? What is Gloda? Is that the reason why its so slow?

1 of my customers are experiencing ThunderBird not responding, very random when it does not respond, Windows 10 Pro 64 Bit I checked that Mozilla ThunderBird is running latest version (x64 en-US) Version 102.3.3 The fixes I have tried are running the setup exe file I have checked email settings are correct Check task manager to see if anything is overloaded such as RAM Memory Check AVG Firewall and allowed ThunderBird Adjusted Windows power management settings to high power plan

A few days ago, Thunderbird asked for the password to my Yahoo mail account. I've been using Thunderbird to access my Yahoo emails for a few years and I haven't changed the password, so I thought it was strange, but I entered the password. I can access my Yahoo emails through other apps without a problem. I think I may have entered the wrong password first time, but checked the password on the other apps, so I know I'm using the right one now. I'm getting the error message "Unable to login at server. Probably wrong configuration, username or password." I've tried removing the email account and re-adding, but it still fails with to connect. Anyone have any ideas, thanks.

When I open T-Bird on one of my laptops, it will not download any emails, and the icon left of "inbox" just keeps endlessly swimming back & forth horizontally.

Additionally, whenever I click "SEND" on an email message, I get the error message below in the screenshot. How can I resolve this issue? Any & all help appreciated.

Thunderbird 111.0b3 shows this behavior:

1. I select a line in the email-list.
2. I press key "1".
3. Thunderbird tags this email as "Important" and colors the selected line in red (screenshot 1), which is fine.
4. I select another email/line.
5. The previously tagged line is not colored red anymore (which is an error, I think - some days ago Thunderbird colored all "important"-tagged lines in red).
6. When I mark the previously tagged line, it's colored red again. So the tag information still exists. It's just not shown as long as the line is not selected.

TB 102.8.0.

Since December 2022, compacting is not working properly. I have set TB to ask me whether to compact when 100 MB would be saved. This has worked fine for years. Since December, I receive a pop-up advising that 237 MB or slightly more can be saved. After compacting, the message repeats every hour or two.

Compacting is actually, working except for the 237 MB chunk of data that either can't be compacted or doesn't really exist and fools TB into thinking compaction is needed. For example, if I set the compaction threshold to 500 MB then the mailbox will grow and I will eventually receive a reminder to compact when more than 500 MB can be saved. Compacting at that point does indeed shrink the mailbox. But, immediately thereafter, if I set the threshold back to 100 MB I get a message that 237 MB can be saved by compacting. Thus, the compact request repeats endlessly, all day long.

I can't take it any more. Does anyone have a suggestion for forcing TB to re-examine or re-index my inbox in a manner that correctly determines its size and ends this nuisance?

Thanks.

Thanks.

When Thunderbird updated to 102.6.1 the other day, my address book disappeared. No more personal address book or contact lists. Gone. (My 'Personal Address Book" went from 2,000 names to 24. Yikes!)

Plus, I can't even type people's names into the emails and expect it to populate like before. I have to search for their emails and rewrite it.

Is there a way to fix this? Or to roll the program back to the previous version?

Since I backed my email list up last month, I've made lots of changes. But if I have to, I'll just re-import and try to recreate what I've done. (Reminder to self to back up more often).

Thanks for any help or guidance. PS - I'm on Windows 10.
