After a power outage I now get this message on all three of my computers but only on some accounts:

"An error occurred while sending mail, The mail server responded: <1234@roadrunner.com> sender rejected. The email address you are sending as must match the email address you used to auth. Please check your SMTP settings, AUP#Out-1500. Please verify that your email address is correct in your account settings and try again."

I know what that means but I'm very confused because I use and have always used ONE <default> smpte for all my accounts and never had a problem until now. Thunderbird even gives the user a choice of whether to use one default account or separate smpte password statements for each account. I still can't send when I try to enter separate urls and/or passwords for each account. Anyone know what's going on? Thanks, Joe

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

Is there any way to go back to simply list Emails in chronological order, and not associated with anyone else? Right now I waste A lot of time looking for the new message I am supposed to have after the pop up which says I received a new message.

I read that I now need a secure mail key so I can access my emails with third party app Thunderbird. I have created a secure mail key at att.com which is part of Yahoo. My email app is att.yahoo.com. I was told the passwords for Thunderbird would be within the profile under the Profile Folder but I cannot find them there. All I want to do is update my password within the Profile Folder and it seems like it would easier to break into Fort Knox.

Our email accounts are attached to our host domain name. We are going to be changing the host domain location from a smaller local provider to Spectrum Internet to service. The email addresses XXX@xxx.com 'will not change, only the server host location. As a backup, we are moving all existing emails located in subfolders under the email accounts to the LOCAL folder (creating new "trees" there) so they are in a permanent location to be unaffected by the server change. From my knowledge... we will not create new email accounts in Thunderbird .... only change the server location, ports, etc for that specific email. I want to confirm with others that this should be the plan?

Hi, I have configured 2 accounts for E2EE using OpenPGP. I can send signed emails &/or encrypted messages between the 2 accounts. However, if I send a "normal" message i.e. no signing & no encryption selected, it arrives as not signed (correct), but encrypted according to the "Show message security" icon. If I send a normal message to an account that has no known encryption setup, then the message arrives and the "Show message security" button is missing (correctly).

Any ideas why this is happening? Thanks for your help.

Thanks for listening: Last week, Thunderbird began returning this message with each attempt to send mail: An error occurred while sending mail. The mail server responded: <tedcomo@chartertn.net> sender rejected. Please verify that your email address is correct in your account settings and try again. I have no problem receiving mail. At the same time, my wife began having the same problem on her laptop, which tells me either Charter, or Mozilla, changed something. I started with Charter. They told me to rename both servers to mobile.charter.net (outgoing mail was formerly smpt.charter.net. No effect. They then had me log into Spectrum and send a test mail directly from my account. It went through OK and they said the problem had to be on Mozilla's end. Any suggestions?

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

Yahoo cannot connect my Thunderbird email to their system. When I go there it pops up that Thunderbird refuses the connection. Yahoo techs say this is a Thunderbird problem. Want to continue to use my Thunderbird. Please Help!

I have accounts from Outlook Mail through GoDaddy and Gmail on my Thunderbird desktop app. After the update on 9/17/24 I am unable to send from any of my 3 accounts. Please help.

Fired up 128.2.1 this morning -- worked fine. Pulled email of my Office365 and gmail accounts no problem. Noticed there was a point update to 128.2.2 - applied the update, but now both Office365 and Gmail fail to authenticate. Time out.

Anyone else seeing this?

In Thunderbird calendar, on 27th Oct 2024, entries added are displayed one hour ahead of where they should be. If the entry is edited, the times are correct, and they show correctly in another calendar app (Calendar on my iPhone). The issue does not occur for events on the day before or the day after, and is the same for a newly added event as for an existing one.

See screen shots. You can see my test event displayed at 11:00 - 12:00 but on editing it is actually 10:00 - 11:00 - the latter is correct.

27th Oct is the day that DST ends in the UK (at 0200) in 2024, but the events are several hours after that.

Nick.
