Older messages in Thunderbird are listed but their content is not showing. I have been using TB forever and I never had that problem before. It is POP3. When I try Folder Repair, the program simply throws out all messages whose content is not accessible (so if my Sent folder has 40,000 messages it comes back with a Sent folder of 2,000). Clearly something got corrupted but I am not sure what. In the picture below, the header is visible but (a) not clickable (different header showing) (b) no content is displayed. I used to copy the content of the TB folder to my laptop and back (while keeping different profile names assigned during installation. The problem seems to have started when I changed profile names and began using identical profile names on both the desktop and laptop. Also, the total size of the folders is around 65Gb, in case there is a size limit. Any ideas? Thanks

Hello, I have recently been unable to create new messages in Thunderbird. I am currently on the latest version, 139.0.2 (64-bit). There is no Create New Message Button, and Control + N does work either. I am also now getting a lot of extra information in the Header Pane. Refer to the Screen Shot JPG. Thanks, Graeme

Hi,

On my desktop, thunderbird does an awesome job cutting spam. While on the mobile its terrible, not just are most spam mails coming thru but some legit emails are getting flagged. Is there some way to make it mimic the desktop.

Thanks in advance

While looking for another setting, I noticed that a setting about how T-Bird handles spam mail. I have it checked. Today, I received a DOOZY of a spam mail, but Thunderbird didn't flag it. It was so obvious spam, as it asked for credit card, banking, automobile license! Also, the Subject asked to update payment info, but the From field wasn't that company.

I have a couple of hundred filters and one of them occasionally kicks in and unexpectedly moves certain messages to a new folder but I can't figure out which filter it is. Rather than me going through every filter manually, can't Thunderbird tell me which filter affected a given message? I'd like to be able to right-click a message and be shown the exact filter(s) which affected it.

I use Thunderbird on a MacBook Air running Sequoia. In the last month or so, Thunderbird has taken to sending emails to my spam folder when it shouldn't. To clarify: I am aware Thunderbird does not have its own whitelisting process, but makes use of address books. All the addresses recently characterised as spam are listed in my basic address book, Mac OS's proprietary "Contacts"; most of the emails were from private correspondents, and as far as I can tell included no spam trigger phrases such as "special offer"! If this problem is insoluble, or inherent to the application, I will be forced to abandon Thunderbird, which is otherwise perfectly satisfactory. Any suggestions?

Hi everyone,

I'm having trouble with my Samsung Email app. For some reason, my emails are not syncing properly. I’ve noticed that new emails are not coming in unless I manually refresh the app. This has been going on for a while, and it’s causing me to miss important messages. I’ve tried restarting my phone and checking the internet connection, but nothing seems to work. I'm not sure if it's an issue with the app settings or something else. Is anyone else facing this issue? Any help or suggestions would be appreciated!

Thanks in advance.

My filters seem to work for emails received but not for ones I've sent. I use the rule "From, To, CC or BCC" combined with a persons email name (i.e. preceding the @ sign) and while From works the To doesn't and remain in my sent folder. Periodically I have to use "Run Filters on Folder" or "Run Now" from within the Sent folder to move everything to their respective folders. Do I have to have a separate rule just for "To"?

Thunderbird does correctly mark emails I choose as spam spam. Problem is, TB fails to move these marked-as-spam emails to the selected spam folder. I've searched for cures here but nothing helps. Now what Mozilla??? See attached pics...
