I'm having some trouble here doing a migration from Outlook 2019. Whether in the latest version or version 31.8, Thunderbird is not finding my Outlook file. Currently, the file is in a non-standard location. Where does it need to be? Will it need to be on the C: drive (which is rather small)? Or can it be found on the D: drive?

I've looked at other means of importing. I tried exporting from Outlook into a CSV file, but Thunderbird does not see all of the columns that were exported. For instance, the email addresses were not in that second column to be paired. That's rather useless.

Another option that came up in the search of previous answers was to export to vCard. It does not appear that I have that option in Export. And individually saving hundreds of contacts as vCards is not a particularly viable option, either.

What would you suggest?

How do I import Apple mbox's from Apple Mail to Thunderbird. The explanation provided makes no sense. Where do you find this profile folder? How do you import if Thunderbird is closed?

How to migrate 'Contacts' and 'Addresses from MS-Outlook 2010 to TB? the Thunderbird so-called 'Import' does NOT work.

Attempting to do so merely produces a 'window' that states

   "Addresses successfully imported from Outlook
    "No address books were found to import

And, surprise, surprise NO data is made available in TB !!! What is WRONG?

I have an archived .mbox file from my old gmail account that is closed. The .mbox file is 23.6 MB (so I cannot import it into a new free gmail account that only goes up to about 15MB). But I do not need to import it into a new gmail or other email account, and no need to upload it anywhere else.

I ONLY need to access and read the archive on my computer.

I have installed Thunderbird 102.1.1 and I followed the prompts to create an account which seems to link it to my current free gmail account (which I don't need or necessarily want).

Under add-ons, I have added and enabled "ImportExportTools NG" but I don't see how to use this tool to import or access my mbox file.

I am not savvy with this program and do not find any of them menus to be intuitive, so simple instructions and no abbreviations would be very much appreciated.

When I go to the far right menu, and I click Tools>Import, I see no options to import an .mbox file.

At this point, how do I import or view the .mbox file using Thunderbird and the Import/Export?

Thank you very much!

I was told to use mailstore to archive old PST files from 2010 outlook which I no longer use. I used mailstore and archived a PST file (have more PST files to do) but now I do not know what to do to get these onto Thunderbird. It called it "microsoft outlook". I clicked on "run" and it ran successfully but I do not know now what to do to use it in thunderbird. Please help

I need to export a lot of emails from Thunderbird on an old iMac. It seems the import/export tool is not on the version I have so I have a problem. I need to get a plug-in to do this now. However, the version of TB is very old and I'll need a new version of Thunderbird to install the plug-in... So the question is - if I upgrade the old TB I have, will I keep or lose all my old emails? I need a sure answer to this because I can't lose these old messages. I don't want to import them anywhere, I just exported text or html for file storage.

Reading thru this forum I don't have high hopes, it all seems vague and complex (even tho we're now in 2021, no less, and ye olde issues rattle on and on). But a definitive answer would be useful to help me decide what to do. Thanks.

Recently tried upgrading from 91.x.x -> 102.x.x. Everything seems to go fine, with one critical show-stopping problem -- any attempt to connect to outlook.office365.com fails. Completely.

Under 91.x.x, I use POP as server type, server name is outlook.office365/com, SSL/TLS, and OAuth2 for connection and authentication security, respectively. Set up this way, port defaults to 995. Works *perfectly* under 91.x.x.

But, using the *exact* same setting under TBird 102, absolutely refuses to connect. At all.

Any suggestions as to what to look for?

I bought a new phone from AT&T and I wanted to use Firefox and get away from chrome and when they used smart transfer to transfer all my data from the old phone to the new phone no open tabs or passwords came with it and now I can't figure out how to import them. I've searched on Google and tried to follow the steps but I don't have the options that they say to use. I have tried installing Firefox on my old phone and importing them from chrome to Firefox on my old phone and then to the new phone and that doesn't work. I managed to export the passwords from Chrome on my old phone to Chrome on my new phone but I can't get the open tabs to and I can't transfer my passwords from chrome on my new phone to Firefox on my new phone. Please, can anybody help me?

I have followed the instructions located here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

but still cannot get my new computer to access my email accounts.

Apparently I have missed something with the profile or the proper path for it but I cannot figure out what it is.

Is there another step to take to complete the migration?

About a week ago my email server, Windstream, deleted our email account. I use Thunderbird all the time and it (of course) just quit. I am very irritated at Windstream and decided to create a Gmail account. My problem is I have used Thunderbird and my windstream email (us4448@windstream.net) for years and years. Now I cannot use it for sending email...BUT, all my addresses are there plus about 25 files that I used for holding important emails for myself. I do not want to lose those. I am hoping I can just add the gmail address to my existing thunderbird account. I have been looking at support....and I see how to add that email....but I don't want a new Thunderbird account......I want the old one with the new email address. I can't see where it says that the Thunderbird will stay the same with just a different address. I hope you can help. Thank you so much for any help you can give me.
