Thunderbird Support Forum

Is there a way to schedule a time (daily or weekly) during which Thunderbird doesn't check for new mail?

I have several mail accounts, some for work, some private. I want Thunderbird checking for new mail on my work accounts during my work hours, and pause checking when I get off work. I don't want Thunderbird to check my private mail while I'm at work (or specifically, up until an hour before the end of my workday).

Eg. I'd like to "tell" Thunderbird to check my work account monday to friday from 8am to 5pm, and my private account every workday from 4pm to 8am and every weekend all day. Ideally, clicking on "get new mail" would only fetch mail for the currently unpaused accounts.

I don't want to have to manually pause checking for messages for each account several times a day.

The "check for new messages every ___ minutes" doesn't help.

Disabling notifications isn't a solution - I need the messages (especially work messages) not to be downloaded from the server (or receive notification that there's mail waiting). I'm looking to "disconnect" from work while keeping up to speed with my private communications.

I have just completely reinstalled Thunderbird v115.11.1 after uninstalling the previous installation. There are two problems, possibly linked to a faulty or missing setting.

Remote images will not display, even after specifically enabling remote images for each email, or after turning on "display remote content" as a default. Also it claims there is a potential security threat with Thunderbird's own web addresses: "live.thunderbird.net." and "addons.thunderbird.net.".

I have attached screen-shots of the error messages, and of a thunderbird email that fails to display its images.

Good afternoon I have 2 accounts in Thunderbird - a gmail and a Yahoo. Both were running great from the time I set up Thunderbird about 2 weeks ago until yesterday when the gmail account stopped sending and receiving. The Yahoo account is still fine. I have not received a message in Thunderbird in my gmail account since, although I have logged in on the web and confirmed that there are incoming messages in my account.

When I attempt to send a message from the gmail account I receive an error message - "Add Security Exception". If I click "View" nothing happens. If I click "Get Certificate" the section "Unknown Identity" changes to "No Information Available". However, when I cancelled the message I noticed a new error message appeared - "Send Error Message" and when I returned to the main Thunderbird screen I noticed a new tab appeared "Certificate for smtp.gmail.com".

As you can imagine, I seem to be getting nowhere with this and as I am only an intermediate user with computers I don't know where to go next. Subsequently, I sincerely hope that someone out there is able to help me. Any assistance would be very much appreciated.

The following are my Thunderbird settings for the gmail account :- Incoming Server Server type : IMAP Mail Server Server name : imap.gmail.com Port : 993 User name : [myname]@gmail.com Connection security : SSL/TLS Authentication method : OAuth2

Outgoing server Description : Google Mail Server name : smtp.gmail.com Port : 465 Connection security : SSL/TLS Authentication method : OAuth2 User name : [myname]@gmail.com

A copy of the error messages as well as the Certificate are attached.

My wife & I have the same PCs running Windows 10 & Thunderbird 115.11.0 (32bit).

We have a hosted web-site that also supports email, and we each have an email account (eg neddy@goon.com.au & minnie@goon.com.au). I've checked that both our POP server configurations are identical but despite that about once a week minnie@goon.com.au receives a warning to add security exception but neddy doesn't. This started happening two weeks ago after a years error free running.

The host has checked that goon.com.au has a valid SSL certificate, so what could be causing the discrepancy and how do I set about fixing it please?

I always use Thunderbird online so no need for offline storage. When I installed Thunderbird, online storage was set on for all accounts. I've since turned this off, but would like to recover the disk space. What Windows folders can I delete? Thanks.

I am using Thunderbird in Windows 11 on an Intel NUC 12 computer. I am using Thunderbird in pop mail for gmail.com and mail.com. I save all important messages daily to Folders in Local Folders. Today I attempted to look for messages in one folder named Family and Friends and found that messages older than 2/14/2024 are missing. I checked other folders and found that they seem OK with messages going back 5 to 10 Years. I tried running repair but nothing changed. Any idea where these files can be? I do have backups of the app data for Thunderbird and am considering to try a prior version but I'm afraid I might lose new saved messages. If I tried to Archive messages, could this be the problem? I have looked in Archive and found very little. Any help would be appreciated. Frank

Please ignore this question. I found my older messages.

There is one correspondent whose emails come in, flash on the screen for a second and then disappear. I find it in Junk. I've got the email addres whitelisted on my provider's filters. How can I intercept this process. It's only the one address. So far. Can I whitelist address on TB? I've got it set to not intercept anyone in my address book and this address is definitely inmy address book.

I have created an entry in my Personal Address Book. When I am in that address book I click on the Import tab. I select CSV file. It provides me a File Dialog to select my CSV file. But then it provides me with a File Dialog to select an address book file. The address book I want to use is the one I am currently "in" in the program. But if I for some reason I wanted to import into another existing address book, I should either have to get "in" that one, or it Mozlla Thunderbird would list the address books it knows about as a selection.

It appears I am supposed to select the file that Mozilla Thunderbird created somewhere. From a search it appears (this is on Windows 11) from the App Store that is somewhere in ..\AppData\Local\MozillaThunder.MZL_h<numbers and letters>\LocalCache\<Roaming | Local>.

I don't understand why I am choosing a file that is already open in Mozilla Thunderbird?

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!

I was in the middle of generating a long "reply all" to a message and wanted to jump to a new page when it would be printed. I absent-mindedly hit Ctl-Shift-Enter and the entire window disappeared and there was nothing in Drafts! Ctl-V just restores the last thing I added to this very long reply! I had been working on this for 90 minutes, doesn't Thunderbird continually update Drafts while working on a long email?

Hi,I have 4 email address & my Default Email is ismda3@westvic.com.au(on SMTP) Regardless which email I TRY to REply to.I receive the Samr Message See attachment I am getting very desperate Thanks Darryl

I've installed TBSync with Thunderbird and my O365 calendar is now syncing.

However, my email subfolders are not fully updating.

I have a # of subfolders I've created in O365 but they aren't appearing in TBSync in order to choose them to sync in Thunderbird. I am getting some (what I would call 'standard') subfolders in TBSync to choose such as Contact, Calendar, Tasks, and some other email accounts I have 'sync'd' into O365, but none of the actual email subfolders for the O365 account itself (i.e. 2024 Financials).

In Thunderbird, the only folders I see to sync (Synchronization & Storage > Advanced)are: Inbox, Draft, Sent, and Trash

What am I doing wrong or missing?

Hi Windows 10 64bits - Thunderbird 115.11.1 (but same happens with Linux Mint 21.3 Cinnamon). It is the 1st time I ask in this forum, so I hope I respect the rules... "Sometimes", in my e-mail "imapmail" sub-folders, "some" files with an added "-1" appear ("draft-1", "sent-1" , ...). They are always newer (modification date) than the file without the "-1". What are they ? Why create a "-1" that consumes space, and not over-write the existing files ? Is there a parameter somewhere in TB to avoid this behaviour (I closed TB, deleted them, but they "sometimes" reappear when I reopen TB ) ? Thanks in advance

installed Ubuntu 2404 on my acer laptop along with Thunderbird, added gmail email to Thunderbird and it fails to connect to google for their security check.

popup when trying to login to google to let Thunderbird access gmail.

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

I think the linux Thunderbird is broken.

I have been through this google process with Thunderbird 3 times windows 10 and 11 and once on an android phone with no problems

Dear Support,

suddenly my INBOX file has a size of 480GB - the mails in all my IMAP folders online is less than 4GB.

How can that happen?

Is there a fix or should I just re-create the account?

Best wishes, Johannes

TIA , Time to Migrate TB Portable to new computer : I was advised that all need to do is Copy this Folder C:\ThunderbirdPortable to new computer . But that doesn't bring over all my email accounts . Pls , what else do I need to do ? Thanks...

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?
