Thunderbird Support Forum

I'm looking to migrate from IMAP Rackspace to Microsoft 365. At the moment, we are setup in Thunderbird but since Rackspace can only handle 25GB of emails and most of my users had to archive their emails locally through Thunderbird. Just checking tool that we can use to migrate the exported archive emails from MSF to PST file so it will be compatible with outlook once the migration is complete, or is there a better option rather than converting them.

I am setting up thunderbird on a new computer running Ubuntu 23.04. I can successfully connect to my gmail account in thunderbird but I cannot add a comcast gmail account. I get an error message

"Could not get OAuth2 details for hostname=imap.comcast.net"

I am using the correct username and password. I can connect to the comcast email account on this same computer through my web browser. I would like to be able to continue to use thunderbird for all my email accounts.

Can anybody tell me what to look at to resolve this problem?

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

I created a compressed (zip?) file from my prior computer. I have not been able to figure out how to get the data from that file onto my new computer. My primary need is for my tasks and events calendar. I have been able to access email accounts without referencing the compressed/zip file. When I insert the flash drive, a message pops up asking me to "insert the last disk of the multi volume set" I don't understand this request. Thanks in advance for any help you can give me

I am no longer able to receive emails from my office 365 account(was originally a go daddy account). I am able to send emails out and its showing deleted emails for over 10 years ago. I just have nothing on inbox. I have taken everything out and reinstalled, even changed passwords. anyone have a idea how to fix.

thanks in advance

One day last week one of three of gmail accounts stopped working in Thunderbird; I can’t send or receive email. I have not changed anything that I know of in either Thunderbird or the Gmail account.

I just checked the email account using a Chrome based browser and it works fine (sends and receives). I have attached three screen shots. Two in Thunderbird and one in browser.

The one from the browser shows I have Thunderbird I have given access to Thunderbird to my gmail account. From the two in Thunderbird one for signing in and the other one with the error and a broken robot drawing is what I get when I select next on signing in.

For the last week, Thunderbird hasn't downloaded the mails from my Strato account. I can still send mails, and read the mails when I log in to Strato. Thunderbird still downloads the mails from my other accounts. It worked fine until now, so I suspect the problem is related either to an automatic Thunderbird update or an automatic Windows (10) update.
