Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?

This is the message I get when trying to send emails: "Sending of the message failed. An error occurred while sending mail. The mail server responded: pgbentley101@gmail.com recipient rejected. Please check the message recipient "pgbentley101@gmail.com" and try again."

Since 2pm AU yesterday, I'm getting the message "Login to server mail.tpg.com.au with username XXXXXXX failed". I have tried everything in checking password, settings but nothing is working. TPG has been back online since this morning, but my Thunderbird is not working. Thanks in advance for any help you can provide.

I've done this before multiple times but it seems to not work now and I'm at my wits end. I think trying to connect more than one outlook accounts is purely RNG at this point. I study and work in a college and need to access to the two emails being used from the schools mail server on my Linux machine.

The problem is that both require Oauth2 and and a seperate login scnreen, I've gotten both, at the same installation, to work multiple times before. But its purely by luck and with no connection to how it didn't break that time around.

I saw a post saying to change the names of the server but that's no longer working, and one saying to use 'smtp-mail.office.com' for one, 'smtp.office365.com' for the other nut no matter in which order ior amount i use those servers its still not working.

Is it possible that Thunderbird sandboxes the accounts properly, and it actually doesn't use the same SMTP server from another account?

Does anyone have any solution to this?

Is this exclusively an effect of my cutting text in a reply-to email for brevity of my reply ?

I'm happy to try to replicate it if someone can offer suggestions.

I sent you a note on Feb22nd explaining that I am having problems sending emails,incoming no problems.I am still encountering the same problems to a certain extent.You did send me a reply,however I have to admit that due to my lack of knowledge I failed to understand.This morning I tried to send a "test" message to a friend.It failed with the message "the message could not be sent because the connection to Outgoing server(SMTP-mail.outlook.com) timed out. However I saved the message to my drafts folder pressed Send and the message went to my friend.Following this I repeated the process with another test,that also was sent. I would appreciate greatly any advice or help you can offer me

When I receive an email and I hit reply and the original body of the incoming email disappears. I need help with the settings to have the original email included in the reply. Thanks, Garry

So hard to find -- hours -- multiple days --- my goodness. I have multiple folders and sub folders with my office 365 account. I'm trying to get away from Outlook. That said, how do I get Thunderbird to include all of my O365 folders? I"m almost ready to give up!!

Thunderbird ver115.8.0, Win11, 64bit Ten or so email accounts running on TB with a mix of pop3 and imap. When starting TB, it usually hangs and the only way out is to close using the X in top right. This is followed by the application wanting to report the problem to Windoze etc. Once I have canned out of this and restarted TB, everything goes well. I have default theme, no extensions or add-ons running. Cache is set to clear on shutdown. I recently deleted all .msf files. The status bar always shows one particular imap account during the hang (hang will continue until TB restarted) - that account is the first account listed in the mailbox tree in LH panel.

I am trying to add my university email account that is managed by google, but I get an error message stating Thurnderbird failed to find the settings for my email account. Any help please?

If you give me an email address I will send you the screenshot of my error message.

Or, call me NOW at [removed from public support forum]

Thank You. Marty Straka

I have been getting constant messages when I try to use Thunderbird about Thunderbird being unable to connect, go to Advanced and lower number. It's at 1. Still get message. Now I can't see my Inbox mail. I've uninstalled and reinstalled and the situation just gets worse. I am so flummoxed I don't know what to do. I'm a user not a programmer. How do I just start over or should I just realize that Thunderbird is not an email program I can use and go back to my ISP's Zimbra webmail?

I use Thunderbird as my email client for Gmail from two different machines, so I have two sets of the same database (over 100,000 emails) (three if you count Gmail's dataset). If I add or delete an email on one machine, it synchs with Gmail, which synchs with the other machine. It works fairly well but not perfectly. Is there any way to make the "Local Directory" for Message Storage some kind of shared file rather than a folder on the local machine?
