Hello Guys,

First of all I was using outlook but since with new update there's bunch of annoying stuff, limitations and ads everywhere, even tho If I force to use old app still get that "Update Outlook" & "Try new outlook" notifications. Thats pretty annoying so I decided to go use Thunderbird. but I have been experiencing significant synchronization issues with my Hotmail (Outlook.com) accounts in Thunderbird. Specifically, when I add more than one Hotmail account, the folders for those accounts do not appear at all. Additionally, when I attempt to send a test email, it shows as “sending” but then the process hangs, nothing happens.

To resolve the issue, I have tried:

• Removing and Re-adding Accounts:

I removed all my Hotmail accounts from Thunderbird and re-added them. During the re-adding process, I cleared the saved passwords (so that the login prompts would reappear) and manually configured the account settings (IMAP server, SMTP server, etc.) & cleared caches on %AppData% Thunderbird>Profile>Imap folder

• Connection Settings:

I verified that the incoming and outgoing server settings are correct (IMAP: port 993 with SSL/TLS; SMTP: port 587 with STARTTLS) and that the authentication method is set to OAuth2.

• Rebuilding Profile Indexes:

I backed up and deleted the local index files (.msf files) in my Thunderbird profile for the affected folders so that Thunderbird would rebuild them.

• Security Software Check:

I temporarily disabled my antivirus/firewall software to rule out any interference with the connections.

Despite these efforts, after re-adding the accounts, the folders still do not synchronize, and during a test email send, the message remains stuck in the “sending” or "Hanging" what ever you call it.

So I need help :D

Thank you.

I have successfully set up one of my email accounts in Thunderbird, so I know the software works as installed. However when I tried to set up my gmail account, and I get to the sign in with Google popup, I get an error saying that the request cannot be performed because it is "malformed". See attached images.

Hello, I did a lot of search and followed all these advises: https://support.mozilla.org/en-US/questions/1229615 https://winaero.com/remove-your-browser-is-being-managed-by-your-organization-from-firefox/

1. I have not entry "DisableFirefoxAccounts" in "HKEY_CURRENT_USER\Software\Policies\Mozilla\Firefox". 2. I have no policies.json file in firefox directory. 3. I have a message "Your browser is being managed by your organization." in "Settings" (about:preferences). 4. In "about:policies" I have DisableFirefoxAccounts=TRUE. 5. in "about:config" identity.fxaccounts.enabled=false and grayed out.

Please help me to turn on the sync of bookmarks. All these listed issues obviously have something to do with it.

I have 2 email accounts. I have been using [edited] @yahoo.com for a long time. At some point, I got [edited] @gmail.com for more official-type emails. I don't care for gmail and use it very little. Yahoo was just okay but they have recently made some changes I despise. A friend recommended Thunderbird so I downloaded it but needed a mozilla account. Google was an option so I used my gmail account. However, I am a long-time Firefox user. Do I now have 2 mozilla accounts?

'spouse hacks my internet activity through firefox. somehow he gets on and then has free access to every movement i make on the internet everywhere. This has gone on for 3 years. how do i stop this?

Hi I have an Imap account, where i mistakenly moved a folder called Bulk to the Deleted folder (see attached). I have tried searching this forum and tried various options but nothing seems to work.

note when i right click on the Bulk folder there is no "Move To" option

I deleted the folderTree.json and the folderCache.json files as these where large and had lots of references to previous folders i had deleted.

Any ideas what my issue may be, thanks in advance for your help

Hello, I have a huge problem with the recovery of my email messages. Due to a network error, I could no longer access my Thunderbird. I therefore had to (!) reinstall Thunderbird. Unfortunately, the reinstall could not access my backup files stored on a NAS drive (Q-NAP). All attempts to reconnect me to the network / NAS drive have also failed with 2 other PCs. However, the backup files are displayed via a PC still connected to the NAS drive. Then, in the hope of being able to transfer the backup via this way, I installed Thunderbird on this PC as well. Unfortunately, the recovery via the import tool does not work with this installation either. The methods described on the support page for "transferring Thunderbird data to a new computer" have also failed Is there still a chance to save / restore my email messages?

My company is switching to gmail and I rely on Thunderbird, so I need to add the account. I've followed instructions correctly, as best I can tell, but I'm sure I'm missing something. No emails are loading. I'm on Thunderbird 128.7, MacOS Sequoia 15.3.

Why does a folder for my "flagship@..." account appear in two places? (See image.) The upper one is a "real" folder in that it contains messages. The one low in the folder list just contains a bunch of links to TB features--no messages.

I cannot understand why the lower "folder" is present for that one account, while the same is not true for my other email accounts. The only difference I can think of, is that the "flagship@..." account is POP3 while the others all have IMAP access.

Ideas?

I'm struggling to understand where Thunderbird stores everything on a Windows computer so that I can use my incremental automated backup system to keep things backed up.

This support article :

[- Where Thunderbird stores your messages and other user data]

only mentions about the <user>\AppData\Roaming\Thunderbird\Profiles folder but there is also a <user>\AppData\Local\Thunderbird\Profiles folder that appears to be used and needed.

There is a ton of other conflicting 3rd party information out there so I'm hoping for a definitive answer here.

My question is : Can I backup just the '<user>\AppData\Roaming\Thunderbird\Profiles and <user>\AppData\Local\Thunderbird\Profiles and be assured that I will be fully able to recover my email client in the case of needing a complete reinstall ?

I was originally with Frontier as my service provider/email server. They have shifted this to Yahoo!. Receiving emails works fine for me, but I cannot get Thunderbird to send emails. I get two notifications when sending... 1) Login to server smtp.mail.yahoo.com with username ******** failed. 2)Send Message Error.

   Sending of the message failed.
    Unable to authenticate t Outgoing server (SMTP)smtp.mail.yahoo.com.  Please check the password and 
    verify the 'Authentication method' in 'Account Settings  Outgoing server(SMTP)'.

I have checked the password dozens of times/tries. I currently have the authentication method set to 'normal password', though I have tried all choices. Type of security is SSL/TLS and port 465.

All of these settings work on my Android phone email app (all 3 accounts I have with Frontier that are hosted by Yahoo! work) I am at a loss. I hope you can help! thank you Jeff B.
