The option "Edit as New Message" is only available when a user right-clicks on the body of an email.

The option is not available in the menu displayed from the "More" button on an email. The option is also not available in the right-click menu on an email in a mailbox list. The option is only available in the right-click menu from the body of an email.

Requiring a user to use the right-click option in a specific area of the user interface is an accessibility issue which should be fixed.

I activated the sidebar of my calendar to display the events. It works fine, but I'm missing the data of an serie of events.

Example: I made an events from Nov. 1 to Nov. 3, entire day. The sidebar shows me only the first and the last day, but it hides the others days - in this example Nov. 2. See attached screenshot.

The "full calendar view" shows this event correctly on all 3 days.

Bug or feature or wrong setting?

I am using Thunderbird as an email client. I have the option set to normally send emails as plain text. If I receive an email that is formatted and then reply, the email is composed as unformatted. I wan the reply to be formatted.

Is there anyway Thunderbird can detect formatting and automatically format the reply the same as received?

How can I reply to an already formatted email so that the reply is formatted?

Good day Thunderbirds

I seem to have done something rather disastrous. This morning when starting up my inbox is empty and though i have sent test messages from other mail platforms and they arrive in my Gmail account they are not downloaded to my Thunderbird. I did change the Gmail conversation option, because i want each mail to be separated. The combining of all related mail confuses me. I have reset the option but nothing has changed. All the other folders are intact and if i open "All Mail" every message is still there including the added test messages. Can anybody figure out what i have done and help me restore my Inbox? What if i re-install Thunderbird or something like that?

Here's hoping. I really do not want to access my mail online via Firefox. Thunderbird is my only way of managing 158.0mail.

When I attempt to write or forward an email, the send option is grayed out and I can not send. But I can reply to an email and the send icon is active. Could this have something to do with the fact that I have had a substantial number of emails and I have used thunderbird for many years causing a pointer to flip? If so is there a way to fix this?

On my Windows 11 PC, when I open my Thunderbird Address Book and click on any entry, or right-click and select any option, a solid grey veneer overlays the Address Book window, and nothing else happens: The feature hangs. I can close the window and continue to use Thunderbird, but all I can do in the Address Book is scroll through the names and email addresses. When this first happened, I updated Thunderbird to release 159.0 (64-bit), but the same thing happens in that version. I've done web and forum searches and have not seen any other reports of this. Any ideas as to why this is happening to me, or how I might fix it? (I've attached a redacted screen image showing what I see.)

So I uninstalled Thunderbird, and just minutes ago tried to reinstall. I got to the donation page, donated, but I never got Thunderbird. I cant get mail from Thunderbird. In fact, I'm not sure it's even installed. Can you help me?

Thunderbird 158.1 – Outlook.com SMTP OAuth2 authentication failure

I am using Mozilla Thunderbird 158.1 (64-bit) on Windows 11.

I recently created a new Outlook.com email account, kim.bailey69@outlook.com, alongside my existing Hotmail and ntlworld.com accounts.

The problem

Thunderbird successfully receives emails from my new Outlook.com account using IMAP and OAuth2, but cannot send emails from it.

The error messages are:

"Login to server smtp-mail.outlook.com with username kim.bailey69@outlook.com failed."

"Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp-mail.outlook.com."

SMTP configuration

Server: smtp-mail.outlook.com

Port: 587

Connection security: STARTTLS

Authentication method: OAuth2

Username: kim.bailey69@outlook.com

Troubleshooting already completed

Verified all incoming and outgoing server settings.

Confirmed IMAP works and messages arrive successfully.

Confirmed sending from Outlook.com webmail works.

Confirmed my existing Hotmail account sends successfully through Thunderbird.

Tried smtp.office365.com as an alternative SMTP server, without success.

Created a completely new SMTP server entry and assigned it to the Outlook.com account. The same error occurred.

Deleted and recreated Thunderbird's saved Microsoft OAuth2 authentication token.

Checked Microsoft's authorised applications page. Thunderbird has explicit permission to send emails, and Microsoft confirms it was used today.

Checked Microsoft's recent account activity, which showed no unsuccessful sign-ins.

Verified with PowerShell that TCP connections to both SMTP servers on port 587 succeed.

Checked that cookies are enabled in Thunderbird.

Attempted SMTP diagnostic logging using MOZ_LOG with SMTP and SMTPClient modules, but the resulting log files remained empty.

When sending fails, Thunderbird immediately displays the authentication error without opening a new Microsoft sign-in window.

My question

Why does Thunderbird successfully authenticate to Outlook.com for incoming IMAP mail but fail SMTP OAuth2 authentication, despite Microsoft granting permission to send?

Is this a known Thunderbird issue, and what specific diagnostic or corrective action would you recommend that has not already been tried?

I would prefer to resolve this without deleting or recreating my existing email accounts, as they contain many years of messages.

I hate when I receive an email with a calendar event attached. This event automatically imports into my Calendar. I dislike this. Now I am getting spam emails with calendar events attached that are importing into my calendar. With so many calendar events it's not obvious I have junk events.

How do I prevent Thunderbird from automatically importing calendar events. I mean, Thunderbird has no clue whether the event is wanted or not. In fact, when I delete an event automatically imported without my permission, an email is sent out saying I declined the event. This is just not reasonable.

Can I turn off this automation because it caused way more trouble than it's worth?
