In Thunderbird 144, we're preparing Account Hub for Exchange, improving folder reorganization, alerting you to certificate issues, and more!Monica Ayhens-Madon (The Thunderbird Blog)
Not all of our progress is headline worthy! But steady, detail-oriented work, described in our latest development update, is a firm foundation for the next leaps forward.

While Exchange Support and Account Hub took center stage last month, we also continued our work on the new Calendar UI and other issues!Toby Pilling (The Thunderbird Blog)
The… cool people… at @thunderbird have released a new feature called "Account Hub". It works exactly with Outlook.com and Google Mail and crashes on any self-hosted mail server 🤦.
Do they even test their crap with independent systems? OIDC support being limited to Google and a handful others in code was one thing, but how does a feature that simply breaks all mail accounts but GAFAM make it into a release?
Bravo + Glückwunsch!

Is it just me or are IMAP subfolders broken in @k9mail and @thunderbird since 12.0?
Just tried Thunderbird as well and I can't download any emails in subfolders. (12.0+12.1)
Used to work fine 11.1.
Is there some switch one needs to flip?

💬 WECHSEL von #K9mail auf @thunderbird
UPDATE:
Es ist total easy. Die Daten müssen nicht vorher von K9 Mail exportiert werden
#Thunderbird installieren und dann den Weg gehen, wie in den Screenshots zu sehen. Das auswählen, was aus #K9mail importiert werden soll - fertig 👌
Thunderbird liest die Daten direkt aus K9 Mail aus
@thunderbird bug?
a team of people manages eg. team@domain #email .
they all use #thunderbird (on #linux) .
drafts stored by some team member, and then sent by another team member, doesn't show thread as replied..
sounds like a known bug? or something else to look into?

Please leave them in a comment to this post and we'll do our best to answer as many as we can in the recording and blog post!
As if I didn't already know it, #Microsoft customer support has proven to be useless. I requested an export of my #Outlook (.com, not the desktop app) email account over a week ago. The page said it'll take up to four days. I contact support and they tell me that exporting online isn't supported. Why offer it then‽
So I downloaded #Thunderbird, connected to my account and have synced my inbox. Currently exporting it using an add-on.
Next job after that is to import it to my new @Tutanota inbox, then cancel my Outlook subscription.
In my laptop #Thunderbird, I have logged in my email accounts. I want to export them to my Android phone. The export QR is not getting scanned by the Thunderbird app (downloaded from F-Droid).
Is anyone else encountering this issue? Can I export using a file rather than QR code?
