Thunderbird Support Forum

Able to receive emails on my Hotmail account on Thunderbird but NOT able to SEND. Started suddenly perhaps after Tunderbird update. Followed article “Thunderbird and Hotmail” at (https://support.mozilla.org/en-US/kb/thunderbird-and-hotmail) and found all settings correct as described. What now?

Mail provider Hotmail.com ISP btinternet.com Firewall part of Windows and AVG Antivirus AVG 22.11.3261 (build 22.11.7716.759) OS Windows 10 Home (64-bit) (up to date) Version 21H2 Installed on ‎17/‎04/‎2021 OS build 19044.2251 Experience Windows Feature Experience Pack 120.2212.4180.0 Thunderbird 102.5.0 (64-bit)

I have two emails dated 11/22/2021 from support@emarkys.com. If I do a global search for them using either “markys” or “emarkys” I get a drop-down window, image attached, that shows an option for support@emarkys.com. If I click on that I get a search tab that opens showing the two emails. If I click on either of them, I just get a blank screen in a new tab. If I click “Show results as list” I get a blank screen in a new tab.

The emails are located in a local folder “__Purchases” If I search for them using a quick search within the folder they are found just fine and open fine.

I have tried global searches for other emails in that folder and some work fine, but others do not, which is to say they fail like the markys search.

I did a right click on the Purchase folder and selected Repair. The folder only has 147 emails so it completed very quickly. But when it is done the folder appears to have no emails in it. If I click to another local folder and then click back to __Purchases all the emails are there.

After the Repair the search problems persist. I rebooted the PC and the problem persisted.

I tried repairing other local folders that also have name beginning with a double underscore and they repair fine and search fine.

NOW this is really odd. I went to my SurfaceGo to try the same search. Periodically I copy C:\Users\...\AppData\Roaming\Thunderbird\Profiles\y6jsbo3s.default to transfer my main PC’s TBird install on that machine. I did the same search on that machine and it worked ok. No problems. Then just for the heck of it I did a repair on the Purchases folder. Unlike the other machine, it appeared to repair fine and all the emails were there without me having to click on another folder. However, when I did the search for Markys I now had the same problem as on the other machine. It no longer worked.

Using TB 115.5.2 in Win10Pro 22H2 OS Build 19045.3693

Since the December Thunderbird update some emails are not appearing in my in box. They are there because when I I do a search they come up. They appear if I use Outlook but not Thunderbird. How do I get help to resolve the problem. Are other people experiencing the same problem but ike me do not know how to report it

Updating to version 38.1.0 Start Thunderbird, Starts up OK. Can view messages and write new emails etc OK. If I select "get messages" OR messages are accessed automatically every 5min. then the whole PC crashes. Three finger salute does not bring up task manager. Only way out is to power cycle.

Thanks in advance for your help Cheers Pete

Hi, thanks for your help in advance.

My Thunderbird keeps stalling every time it checks the Hotmail messages. The "thinking" wheel keeps coming up and it freezes for the duration of the process of checking the Hotmail account for new messages.

This didn't happen before, and it doesn't happen with other email accounts (gmail or others). I believe it started with the last 2 updates or so.

I am using a Macbook Pro 16, 2019, 2,3 Ghz, i9, 16Gb, and TB 102.3.3

I look forward to your suggestions to solving this issue since it interferes with my workflow every time I have to wait for TB to unfreeze after it finishes checking the Hotmail account.

Thanks again. Best. Nacho.

I get this Error message when I try to send emails from my outlook email address in Thunderbird. Basically asking me to enter a Password to login to office365 server ! My Password is correct, and has not been changed recently.

Any ideas please ?

Failed to join the web hosting product identified by Thunderbird when initializing the mail server and account.

Would anyone have the link to this service product?

I have updated to Thunderbird 38.1 running with XP Pro. Thunderbird fails/crashes every time I switch users. We have 3 account profiles and failures occur on all 3 profiles.

Crash reports cannot be sent to Mozilla as errors in transmission occur.

While Thunderbird is working it is good but the constant failures are frustrating.

Today I can not access my thunderbird email. Must be the Google issue, worked yesterday. I have updated to the latest 91.10.0 release and still have the issue. Appears the update that should have updated the settings for this google situation, did not apply. Followed the instructions for possible correction: changed the accept cookies to all copies and always. Do not see a Config Editor under the General Preferences. At least not an area labeled as such. Do not know the status of javascript within my system. Current passwords do not have the oauth preceding any password. What steps should I take to correct this issue and be able to retrieve my emaii? Could not find a phone number available to contact support on this matter. David Brunton

I currently have TB 102 running on a Linux Mint desktop. The email is POP3 from att (actually snet). They require a different app password for each computer. I have the different app password. I want to use my Linux Mint laptop to access my email and use a backup of the desktop's profile when the desktop is out of service. Laptop does not have any .thunderdird folder yet as TB has not been started. I am looking at the http://mzl.la/1ApHiU3 support page. It seems that these instructions are replacing Laptop's hidden .thunderbird folder with desktop's .thunderbird folder. This seems odd since Step3 of "On your Destination Computer", opens Thunderbird. Won't that create a .thunderbird folder with new installs.ini and profiles.ini files? They will be replaced in Step8.

I am concerned that Step3's newly created .ini files (which have a different hash that links them) will be lost in Step8 and there is some dependency on that hash value that is not clear. Is that hash sent to the email server so that they can identify the machine/app that is accessing their server?

Is there a more appropriate support page for what I need to do? I am not clear on the subsequent steps to launch TB on the laptop and change the password on the laptop. At some point I would need to reverse the direction to bring the Laptop's Profile back to the Desktop. Any advice would be appreciated.

It appears in the left column after I set up my account and seems to have no purpose. Right-clicking it and selecting Delete or Rename does nothing. It shows up as a msf file in the Profiles folder but moving it to the trash has no effect because a new folder is created when I restart TB.

Previously one could tap view, and see exactly all the transmission details of emails, especially spam or phishing, and I could highlight, copy and paste to send to SpamCop or phishing.gov.uk so the sender could be traced and blocked. This feature seems to have gone with the new update. Sorry if thick but am 79 yo Geri. Cheers and thanks

when clicking an email link this is shown

"Thunderbird is already running, but is not responding. To use Thunderbird, you must first close the existing Thunderbird process, restart your device, or use a different profile."

How do I make Thunderbird instead open a new email?

This is on Fedora

Hi, I've had this problem two other times with various upgrades, where my setting no longer works. I need horizontal lines between message headers in all folders. My eyes need the lines to be able to scan across and not get lost. I am using TB v115.3.3 on Windows 11 Home.

Here is an old version of my problem: https://support.mozilla.org/en-US/questions/1277758

Here is the full content of my userChrome.css file that is located here: C:\Users\Victoria\AppData\Roaming\Thunderbird\Profiles\hid4pw25.default\chrome

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

/* Add bottom border to thread pane (message list) */

1. threadTree treechildren::-moz-tree-row {

 border-bottom: 1px solid grey !important;

}

Thank you for any help.

This question was asked here and the answer worked for some years, but no longer does.

The method was pretty simple, just change browser.tabs.loadDivertedInBackground from the default FALSE to TRUE.

An update in the last few months (not sure which) broke this. So, what is the new way of doing this?
