Thunderbird Community Forum

I periodically can not send emails, the message displayed is: An error occurred while sending mail: outgoing SMTP Too many concurrent SMTP connections

Please advise Thank you in advance

After escaping from the blank screen it says it could not access server. But my credentials are copied from my gmail login that works fine. And I have checked the configuration with other gmail accounts that are running in Thunderbird and they are the same. So why am I getting a blank screen? How do I get my google permissions authorization form to show up?

This procedure now fails to work for a gmail account that I have put into Thunderbird successfully in the past.

I went to a lot of trouble to get all my email accounts into Thunderbird. I really don't want it to fail me now.

Thank you to anyone who can help.

When I am supposed to get a google sign-in from Thunderbird, all I get is a blank white window on my computer. I another computer it works. I have tried a lot of settings and cleared a lot of passwords and cookies. Nothing I have found after hours of trying has helped.

I hope there is something easy I have overlooked.

Thank you for helping.

since upgrading to nebula TB is very slow to open messages and also very slow to delet messages -unless this can be fixed I'd like to go back to the previous version which I think is 115 - anyone know how to do this proerly without ruining things

Weird Data Corruption. Subject in Preview mismatches with Actual Content of the Message.

The mismatch was not due to cache or refresh because it persisted through Thunderbird restarts and also moving the message across folders.

Thunderbird Version Number: 128.1.0esr (64-bit) (on Linux Mint Wilma)

I have two o365 accounts from different companies. One of them works fine the other I get "user authenticated but not connected" I turned off ipv6 globally and specifically for outlook.office.com and tried relogging even revoked the app and allowed it again. Sending emails somehow works but it keeps loading even after the email is received. I'm on Linux tried both native and flatpak app. These account also work just fine through davmail. The irony is that the account which doesn't work recommends Linux users to use thunderbird that's what promoted me to switch to it instead of davmail.

When I originally set up a POP account in Thunderbird for Mac some years ago, my address was at interchange.ubc.ca, then the POP server migrated to mail.ubc.ca

In Account Settings, my e-mail address, POP server name, and Copies and Folders names all reference mail.ubc.ca (as they should).

But in my ~/Library/Thunderbird/Profiles/<profileName>/Mail folder, the POP folder is still named pop.interchange.ubc.ca.

(N.B. <profileName> is a placeholder for my actual profile name, not displayed here for security reasons)

I have many filters set up to move messages to specific folders at the same level as my Inbox in my mail.ubc.ca POP mailbox, but whenever I restart Thunderbird and run a filter, I get the error, "The folder 'folderName' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder." (N.B. <folderName> is a placeholder here, for example it might be "Trash")

I can then select the destination folder in the "Choose folder ..." dropdown menu and run the filter, but whenever I restart Tbird, I get the same error all over again.

In the msgFilterRules.dat file for this account, I see lines like these: "actionValue="mailbox://<username>@pop.interchange.ubc.ca/<folderName>", e.g. actionValue="mailbox://<username>@pop.interchange.ubc.ca/Junk"

[N.B. <username> is a placeholder for my actual username

I'm wondering if this is due to a mismatch between the POP server name and the name of the POP mailbox folder in the Finder. Is it safe to change the name of the latter to "pop.mail.ubc.ca", and should this fix the problem? Will this automatically update the server name in the msgFilterRules.dat file, or do I have to edit it to replace all references to "pop.interchange.ubc.ca" with "pop.mail.ubc.ca".

If it is not safe to do this, or it is unlikely to fix the problem, any advice as to what to try instead would be greatly appreciated!

Many thanks!

Is there a way to set/change the organizer of an event in Calendar?

I'd like to create an event but set someone else in my address book as the organizer to whom all event replies will be sent. This is useful, for example, when my account is limited to ME@localhost and my Mail Transport Agent does address conversions.

thanks!

I deleted a work account (hosted on google) and I keep getting pop-ups from Oauth to authenticate it. Looking at the troubleshooting information while it is not in the mail and news accounts list it does show up as an account.

Also, looking at the profile directories I seem to also see possible accounts that were deleted a long time ago but still straggling around.

How can I resolve this?

Thanks leon

All email files on this windows10 laptop appear to have become encypted (inbox and sent and all defined folders). Able to access and view them all, but when sent to printer, they remain encrypted and print encrypted code. Have tried reinstalling Thunderbird, over previous installation.Have not tried uninstalling thunderbird before reinstalling.

I have two email accounts coming in to my Thunderbird app on the desktop. One account stopped loading messages to my inbox. I can get the messages on my phone for that account if I access them I don't use Thunderbird. I'm getting message that certificate if not valid. I did the trouble shooting for Thunderbird and cleared the cache. Can you please help? I downloaded the trouble shooting file if needed.

Hello, If you could explain what happen that caused my emails below a given point, having been received before the emails above said given point (about 20 emails ) will not open as usual, but instead I need to open in a different tab after right clicking. If I go to "conversations" I can see my incoming email. Hope that sort of explains the problem that I don't understand? Thanks for any help. Lee

I have comcast/xfinity email. I reset my Comcast password. Now Thunderbird is asking me to enter a new pawword. I enter it, and tell it so save it, but it doesn't work.

Does Comcast email have a different password from the main password?

How can I fix this problem?

When I try to open Thunderbird, a message pops up that says the application had a problem and crashed. It also says that the crash reporter is unable to submit a report for the crash. It then says "Details: The application did not identify itself."

What do I do to fix this?

Thank you.

I couldn't stop the 'need password' popups so I decided to uninstall my Hotmail account from Thunderbird and reinstall it. Unfortunately I am unable to reinstall it. When I try I get a message that the incoming server exists. I go into the advanced configuration and all ports are correct and Oauth2 authorization is selected. I changed to normal password and got the same error message. I checked and there was no outlook server under passwords on output server.

Next I opened a new outlook email and tried again. Now I get the error message 'could not get issuer for oathe authentication". I changed the authorization to normal password and got the error message 'Unable to log in at the server. Probable wrong configuration, username or password. I am sure that I am using the correct username and password.
