Few things:

TB frequently freezes, not responding. I assume it's due to huge file size and number of emails stored offline. Also, I often have to "repair folder" to the inbox because the message body is commonly just scrambled text or contains the message from a totally different email message or file attachments are missing, etc....

I'm using AOL, so I've accumulated about 50K emails in my account. I separated them by year, on the AOL server, in an attempt to reduce folder/file size(s). Doesn't appear to help, but doesn't make it worse. When I search for an email or sort by a column, it usually freezes for a few minutes up to a full lock up...

Also, no matter if the inbox is fully synched, the message at the bottom always seems to be "Downloading Message # out of 48,915" or whatever the new email count is at the time... After it completes the synch, I notice it starts over from "1 of " after some time.

Is there a max file/folder size that TB can handle for offline storage? Is there a way to increase the size? I don't want to delete emails as I need to reference years of archives on a regular basis. Do I completely delete (and data) and reinstall?

Thanks!

I have not been able to get Thunderbird to work with my outlook.com email address since MS requires 2FA, for me about 3 days ago. My server configuration is :

W10/32 bit fully patched Thunderbird 128.2.3esr (32 bit) POP Mail Server outlook.office.365.com, port 995 my MS "user name" which is my email xxxx.outlook.com SSl/TLS OAuth2

       In SMTP Server 

outlook.office365.com 465 SSL/TLS OAuth2 xxxx@outlook.com

The error message I get with this config says "Thunderbird could not connect to server outlook.office365.com; the connection was refused".

I DO NOT have an office365 account.

Logging to www.outlook.com with my UN (=outlook.com email address) and password WORKD. Although the lack of a way to turn off the MS spam filtering makes it useless. I have put some MS thing on my phone and I have to do some 2FA thing when bringing up www.outlook.com.

Help please.

Hi,

Is it possible to add a Thunderbird Settings option to show its email notifications on a Windows 11 PC ONLY when Thunderbird window is inactive and hidden behind other app windows on screen? When the client window is active, and new emails arrive and appear in it, there is no need to dublicate it by popup notifications, so this feature is redundant and should be auto off.

Email won't send with error message: "Must issue a STARTTLS command first. Verify email address in setting first and try again." I went to my settings and check that STARTTLS is the email connection security and my email address is correct.

I don't have and edit for account settings so I made sure it was correct then closed and restarted TB and restarted my computer. Neither worked for me.  I can receive message but not send anything out. 

I have started using an older version of T-Bird,[since v. 115 is such a pain in the ass] but most of my contacts are missing even tho it says the Profile is the same as that in 115.10.1 checking the profile contents, via notepad, it appears to contain all the contacts but they don't show up.

Trying to configure Thunderbird to work with hotmail again. It stopped working a few days ago. Following the 6-step instructions at the end of the thread on this page: https://support.mozilla.org/en-US/questions/1436296

At step 3 I don't have OAuth2 in the drop-down menu. Just

No authentication Normal password Encrypted password Kerberos / GSSAPI NTLM

With OAuth2 selected in the places it *is* available, I just get Host contacted, sending login information... ad infinitum.

How do I fix it? Thanks.

Thunderbird 115.15.0 on Windows 8.1

Sometime around Sept 18-19, the Local Folders has become 'hidden' and not fully visible. My wife thinks she chose the 'Hide Local folders' option from the 'folder pane options'. I tried to disable/re-enable that option but Local Folders still do not show, even with that option disabled. There is 1 folder in Favorites that does show it is a sub-folder about 5 levels deep, (although most of the upper level folders will show emails when selected). There are 20+ folders shown in the Recent folders that do show emails as expected. When i select the 'All Folders' option under 'Folder Modes', nothing happens. The display does not change, and when i click back to show the options again, 'All Folders' is NOT selected (even though i just had selected it!).

I read though several topics related to Local Folders, but i do not see this specific issue. I verified the Local Folders directory on Windows does have data (.sbf, MSF, and File) and all the sub-directories. It contains about 4.3GB of data. I tried Copying the actual Local Folders directory on Windows to a new directory, and then changed the Local Folders Account settings configuration to use that new path, however same result, Still cannot see Local Folders entire directory structure. Using TB v128.30.esr. Have it configured to apply updates when available. I saw in the release notes there were updates released on or around Sept 18-19. I initially thought the Local Folders index was corrupted somehow on Windows, so i tried the 'Repair Folder' option on the 5 levels i could see in the 1 Favorite that was showing, especially the top level, however that did not change anything. Since I cannot see the whole Local Folder structure, i cannot try on any other folders. I now suspect there is an issue with 'Hide Local Folders' function. that seems to be what has caused all this.

will attach screen caps showing the menu options, and Recents/Favorites. I can provide others if needed. thanks for any guidance. Eric

Every time I try to forward an email in Thunderbird I get this message. I can get emails in Thunderbird, Firefox (from Comcast) and Microsoft outlook. Firefox lets me into the my emails by my signing in thru their discovery website and I can forward them. I'm not sure about Outlook.

You don't have permission to access "http//login.xfinity.com/login" on this server.

I have been using Tbird for years and have never seen this issue. I have a client that when she sends an email, usually with PDF attachments, the email goes to the recipient but what gets placed in her sent folder is the header followed with random characters.

For example, this is what showed up in the sent email folder from a email sent with PDF attachment. This does not happen all the time but certainly happens enough for concern.

Thanks in advance

The email goes on like this for a while and ends with some more header info.

I can't find a setting to adjust the print size of an email anywhere. I've tried searching for the answer online but all I find is how to increase the font size on the screen. I want to increase it on a sheet of paper.

Been using TB for about one month. When I look at the real Inbox with a text editor, the first two messages received in mid-September have the initial "From" line which separates messages looking like this:

  From - Thu Sep 12 13:02:54 2024

All the other messages I have received (and stored locally) since then have their initial "From" lines that look like this:

  From ^M

where my text editor displays a carriage return as ^M (caret cap M). There is no hyphen and there is no timestamp for all the other (later) messages. I have upgraded (recompiled) TB at least a couple of times since those first two messages arrived. In TB everything looks fine, but if I use a different MUA to attempt to read and display the several hundred messages that are in this Inbox, only the first two messages from mid September show up. Could this be a bug? The TB Inbox is formatted in standard mbox format, and should be readable using a different MUA.

Am I missing something? Thank you in advance.

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

I started to learn DevTools for Thunderbird, because I want to fully customize my TB. And I'm stuck with such thing. I want this: <Picture 1> Both search boxes are blue.

For the upper search box is this code snippet responsible:

input {

 position: absolute;
 inset: 0;
 width: 100%;
 height: 100%;
 font-size: 1rem;
 border: 1px solid var(--color-gray-40);
 border-radius: var(--button-border-radius);
 padding-inline: var(--padding-block) var(--search-icon-clearance);
 background-color: var(--layout-background-0);

}

So I change it to:

input {

 position: relative;
 inset: 0;
 width: 100%;
 height: 100%;
 font-size: 1rem;
 border: 1px solid #82D6FF !important;
 border-radius: var(--button-border-radius);
 padding-inline: var(--padding-block) var(--search-icon-clearance);
 background-color: var(--layout-background-0);

}

And then I have this <Picture 2>

So I get additional frame. But I don't want it. And I can't understand, why I see this additional frame in this place?

Can someone explain me this please?

When I open my Thunderbird e-mail on my PC, I immediately receive a pop-up saying "failed to connect to server hp110.hostpapa.com." Hosp Papa is a web site manager that I use, not a server, at least that is what I was told when I called them about the issue. I ignored it for a while and everything worked, but now I can't send e-mails. I can receive no problem. I have a business to operate, and it is getting very difficult when I cannot receive e-mails. Can you please tell me what to do? How do I find out what version of Thunderbird I have? Thanks! Bev

I use SMTP settings

Description: smtp.office365.com Server Name: smtp.office365.com Port: 587 User Name: mypersonalaccout@hotmail.com Authentication method: OAuth2 Connection Security: STARTTLS

but TB is incapable of sending email. Either I got dialog https://software9119.technology/__other/tb/dialog.png or error https://software9119.technology/__other/tb/timed-out.png.

I tried cleaning cache and made some re+/search with no avail. There seems to exist some Authenticated SMTP but this is only available on Exchange 365 while this is my personal Outlook.com account.

Same question had Bill Swartout at 1/9/24, 2:30 PM with no answer, https://support.mozilla.org/en-US/questions/1423404#answer-1629472.

Hi guys, yesterday after trying to search for a message on my local folders suddenly all the messages dissapeared, the folder structure remains but the messages stored on them are gone. I've checked if it was a hard disk problem but it's OK, I ran a recovery software but couldn't find any message. I had 5 years of mail stored on local folders and now are lost. I've found in forums the same problems with Thunderbird v115.15.0. Is any way to recover the messages?

I would appreciate any help with this.

PERCY

With the recent "drive" by microsoft to "2 step auth" (ie.oauth2) and its final steps of implementation, my older imac (ios 10.11) which was working with thunderbird (78.14.0 (64-bit)) now can not handle my outlook email account. During the process and adding back the account, you jump thru most of the setup and authorizing steps but it ultimately fails with the following

"AADSTS7000112: Application '08162f7c-0fd2-4200-a84a-f25a4db0b584'(Thunderbird) is disabled."

I guess there is some older version checks that have diabled this app??????

I am not able to update to any newer tbird version because of the "dated" imac. Is it possible to cause the app to be enabled somewhere in azure or whereever this check is done?

I know my system is old but so am I ... :-) Any guidance on how to get this working again would me much appreciated . I tried both "pop and "imap" settings but both resulted in the same error.

I do not have any problem sending messages that I originate, but when I reply to a received email the message that I send appears in my inbox, but does not get sent to the intended recipient. Can you suggest a solution to that problem?
