I am running Thunderbird 78.1.1 on a Mac (OS 10.13.6 = High Sierra). I've been using Thunderbird as my email client for over a decade. On Monday Thunderbird asked me to update (to 78.0.1) and after I did that it stopped sending or receiving email via my work account, which is via smtp.office365.com. Thunderbird has frequently been slow via both my accounts, but now it is timing out ~80% of the time to my gmail account and 100% of the time on my work account. I did not change any server or email settings. My ISP is AT&T Uverse, my firewall is the built-in Mac firewall and I turned that off without effect. I am not running anti-virus software, to the best of my knowledge. The error messages I'm getting when trying to send email are

"Sending of the message failed. Peer’s Certificate issuer is not recognized. The configuration related to smtp.office365.com must be corrected."

and the same thing using the gmail server: "Sending of the message failed. Peer’s Certificate issuer is not recognized. The configuration related to smtp.gmail.com must be corrected."

Two screenshots of my smtp settings are attached.

Thanks for any guidance!

After a windows update my computer decided I was on a trial version of windows and made a mess of a lot of things. Not a problem I thought as I had everthing backed up, including firefox and thunderbird (on 78.1.0) both as mozbackup files and by copying the contents of the profile folders. Thats the background, now the problem. Thunderbird refused to recognise my mozbackup restore. Not a problem I though I'll just copy my thunderbird 78.1.0 profile into the 78.1.0 profile on my restored ssd.

It doesn't work. Thunderbird won't read its own profile!

This is very frustrating and I can't see a way round this, any help would be gratefully received as I'm dealing with emails over the last ten years

I am on Windows 10, Thunderbird 80.0b1 (32-bit) and have an HP OfficeJet Pro 8720 printer. None of the print.printer lines appear in my Thunderbird config so hitting the Print key for an e-mail opens up a totally blank box. All of the print.printer lines do appear in my Firefox config and I can print content from it.

Used to be able to create a calendar event that spanned multiple days. Now, for example, whenever I put in 8/15 for start, and then 8/16 for end, the start automatically changes to 8/16.

Tried checking/unchecking "all day event" .

No only that, but I went to take snagit photos of the screen and now both messages are gone. Checked my account via the web and they are gone.

Stopping the use of tags. This is not the first time, emails are gone. They just seem to disappear.

Love Thunderbird, but I am in business and I can't afford to lose emails.

Thunderbird is downloading 3 copies of each email from the POP server.

When inspecting the headers, each of the copies has a different X-Account-Key value, one of which is correct and corresponds to the account being accessed, the other 2 belong to different accounts and yet down a copy of the message intended for the correct account

So checking an email for account11 is downloaded 3 times, once for account 11, once for account 6, and once for account 17 !! Account details from prefs below

Acct# identity 11 george@domain1 (also default account) 6 george@domain2 17 george@domain3

Very strange....

Can anybody help?

I have about 20GB of business emails from last 10 years in my Thunderbird. I want to upgrade my operating system in mac from Hi sierra to Catalina.

Is there any other issue I need to address in Thunderbird configuration before installing the Catalina?

I have my Mail stored on a NAS (in X:\My Documents\Mail) and it has been working fine for years. But recently the NAS failed and I have to go back to my 2 week old backups.

I have an internal HDD (drive D:) that is not being used for much else so I copied my Mail from the backup version of X:\My Documents\Mail into the internal drive D:\My Documents\Mail. Then, using "Control Panel\Administrative Tools\Computer Management\Storage\Disk Management" I changed the drive letter of the internal drive from D: to X:.

Now my mail files are stored in X:\My Documents\Mail - just like the good old days.

But when Thunderbird starts up it is an almost totally blank screen. The Toolbars are there but nothing else, and even then, the Toolbars are not working. There is just nothing there. No mail, no folders, no account details, no Address Book, nothing. Not even an error message.

I notice in Task Manager there is a little Thunderbird activity at first, but that soon dwindles to zero and still I have that near-blank screen.

There are some other applications that expect to find their files in X:\My Documents and they are working just fine on the newly restored internal drive X:. So that redefinition of drive letters seems to be OK.

What have I done wrong? How can I retrieve all my mail, folders, address book, etc?

Currently I have Eudora 7.1.0.9 on a Windows 7 computer. I’m getting a new computer with Windows 10. Since Eudora is no longer supported I’m looking to switch to Thunderbird 78 (which I gather is the latest version). Will Thunderbird 78 import all my Eudora 7.1.0.9 files? If it will, am I correct in assuming that I’d need to install Thunderbird 78 on my current Windows 7 computer and import the Eudora files to it? Then how do I transfer the new Thunderbird on my Windows 7 computer to my Windows 10 computer?

Sorry if topic not quite right.

When backing up Thunderbird - every month or so (for many years) to a separate HDD - always thought that address book was within the -- Roaming - Thunderbird - Folder. Can anyone say please, where to find the address book on the HDD as I now think, to the cost of my wife's PC's faulty HDD, it has to be exported for back up as it appears not(?) to be automatically backed up when backing up Thunderbird. Previously, not sure how long ago, I seem to remember content of emails being shown within the Thunderbird Folder, appears not to be so currently.

My wife is a little upset because my misunderstanding has caused her the loss of her email address list. In future both on mine and her PCs I I think I'll have to create folders header "E Mail Address Backup" - am I wrong?

Thanks in anticipation

6 months ago I was given advice on how - manually - to save/backup/copy a profile, and how to recover/copy back the said profile during a windows version upgrade. Either the advice was incomplete, or it just didn't work, and altho I tried it several times it was a disaster. The only way back was to laboriously copy the profile details from another unaffected PC to the affected one. Furious, a c**kup of the 1st order.

Tonite I've read the article on profile manager, and that old fury returned, and this post is the result. The article just doesn't cover this most basic of profile actions - backup and recovery. The best it can do is refer to the way the firefox browser works, but it's still manual. And who wants to be told to refer to a browser when they are concerned with a mail program???

But I've noted and used several times the way the Thunderbird address books work; export and import from a menu option. A profile may be a tad more complex, but the files clearly exist so "menuing it" removes manual actions with it are hazardous to the desired end result and ultimately to the reputation of the product. Why cannot the simple action of backup and restore to safeguard a profile and re-use it on a new install if necessary follow the same process? - On the 'old' program, click menu backup/export profile, select a folder, Ok. - When new install is up, click menu recover/import profile, select folder where it is, choose apply, OK If it necessarily involves a re-start after a new profile is applied, so what is new?? This way there's no manual interpretation involved, just click and use a navigation panel, OK.

I have been using Thunderbird for about 3 weeks now. Sometime in the last week, as I was composing/saving/sending in the usual way, the Draft folder counter started adding 1 to the total number of drafts in there. So now, when I can go to the folder itself and see it is actually empty, the counter is still telling me something is in there. The problem is not earth-shattering, but a) it is annoying and b) I am worried that it might signify some wider problem now or later.

bold textHi all,

I'm having trouble syncing large calendars (they go back to 1999) using CALDAV. Both calendars are stored on my Synology NAS and sync just fine to Thunderbird on my MacBook Pro.

However, Thunderbird on my Windows PC refuses to sync them, giving me a message that the calendar 'currently is unavailable'. I get this both using built-in sync and using TbSync.

A small calendar I tried as a test, syncs just fine.

Does anybody have clue as to how to solve this issue?

Thanks so much for help!
