Thunderbird Support Forum

When I opened the Thunderbird Calendar this morning 99% of information, appointments, meetings, birthdays, etc. are missing. The Monthly view shows one or two events, the rest of the days are blank.

I have my University of FLorida (UF) email downloaded in thunderbird. It is IMAP so whenever i delete something on the UF website it then deletes in Thunderbird and vice-versa. I am now experiencing for the first time in years a few emails missing in Thunderbird, but that are in the UF website. See for example the email below from PC-Progress I received yesterday (5/16th) at 10:28 am. It shows on the website under imbox, but not in Thunderbird. When in Thunderbird I put the PC-progress email in the search box it founds the email (see screenshot below), but when I click on it it goes to the conversation and the email is not there. Any suggestion?

In a previous thread 5 years ago, it has been asked how the e-mail filters can be backed-up. Back then, the suggestion was to locate the msgFilterRules.dat in the profile folder.

I just created a new user profile in Thunderbird 91.9.0 and I created some new filters, but the file msgFilterRules.dat hasn't appeared in the profile directory. Has the file been changed? Any tips on how to back-up the filters? Using Ubuntu 20.04.

SOLVED: one has to do the following steps:

1. Go to Help>More troubleshooting information>Profile Directory > Open directory 2. Right click, open in Terminal 3. type the command "find . -name 'msgFilterRules.dat'

this will list all the filters, dependent on different e-mail servers

I recently updated Thunderbird to 101. from a much earlier version, and of course it destroyed all my custom settings. I found most of the addons I had previously were no longer valid. I managed to get a lot of the previous functionality back with settings and other addons, but one still has me stumped. When I bring a message up, I have it set to fully occupy the screen. There are some buttons at the top of the message header I was able to get working, like Reply, Forward, and Delete. But 2 that I use (or use to use) a lot are the Next message, and Previous message buttons. I can't seem to find any way to get them going again. Is there some way to get a link button, or icon for these in the message header?

My Tbird no longer shows me a "Send" button once I have written a new email or am trying to reply to a received email. I've searched for possible settings regarding this, but have not located any in Tbird's help section. How can I repaid this loss?

Hi, I removed an email account that I no longer use via deleting the account under Account Settings - Account Actions - Remove Account. The email account is now removed, however I am regularly being prompted to provide the password for this removed account. What can I do to stop this message?

Many thanks

I can not get thunderbird to bring over email for 6 days now I get the following error everytime. (Sending of password for user .........................@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later.) I have tried creating a new password on the server account and restarting thunderbird with the new password . Did not help. Any Suggestions?

Why would Thunderbird be refusing to add folders to the three e-mail addresses I use it for? One account has 24 folders , next has two, last one has five. I've looked at all the switches in Settings and can't find anything indicating I'm locked out from creating new folders. But I am.

If anyone has any ideas on this, please let me know.

Thank you.

I am setting up a newsletter which will go to my five hundred contacts every day. can I download mozilla thunderbird, and will it be acceptable to do so with that email using another platform email marketing platform? My list has given me permission (signed up) for this, there is no cold emails, but they are forwarded on for several generations, from one person to all their contacts, to theirs ,and on and on. Would this be permissible with thunderbird? I thank you for your attention to this matter.

Have asked SEVERAL TIMES WITH NO RESPONSE. Need to delete old email account in thunderbird. Tried posted solutions but nothing works and it is always asking for sign in/password which will not work. PLEASE HELP...Very annoying.

Under both Windows 7 Thunderbird 101.0b9 (32-bit) pop and imap all messages from the previous day are being deleted from my inbox on all systems accessing my e-mail account.

I have previously been running pop when this event started about 3 weeks ago. On the advice of my internet provider who said they investigated my mail account I converted to IMAP.

I receive mail on my cell phone, an IMAP laptop and my IMAP desktop. The laptop and desktop are windows 7. The lap top and cell phone are set to never delete. My desktop is set to move deletes to trash and to never delete. If I move all the mail that has accumulated overnight from my laptop to a local folder, it is retained there even when the mail on my desktop disappears. If I do not and the mail spontaneously disappears, it is gone from all devices.

If this appears to be a beta related problem, I would be happy to leave the beta system if it did not entail reinstalling Thunderbird. In the meantime, I will refrain from updating beta unless it is a solution to my problem.

I get emails from Reddit through IFTTT, and each and every one of them will not format in TB so web links are clickable. I've attached an example. (Note, I have no issues with any other emails with web links, just these from IFTTT)

Would be grateful if someone knows how I might correct this.

After a recent upgrade of Thunderbird, I am getting the following message: "A unique identity matching the From address was not found. The message will be sent using the current From field and settings from identity ------------" In addition to no links being "live" in received messages that are in my Inbox, there are no longer options available to "reply" or "forward" etc.!

I haven't a CLUE how to troubleshoot this and have never had this problem before in the 3 years I've used Thunderbird?

Hi, Quite recently, my main INBOX (unified folders) does not have the incoming counter working. It used to pick up everything from all addresses. I have obviously done something to make this happen, but I don't recall touching anything ! When things are running ok, I just leave 'em alone. Coincidentally I'm sure, but it started around my last 'update'. Any ideas please ?

I have an account with Spectrum that I used for years. Now I've added a second Spectrum account, but I don't know how to navigate to it. I looked in Tools>Preferences but didn't find anything there.

TIA for your help. SweetTasha
