outlook on one drive to Thunderbird on another

Posted

changing old hard drive with Win 7 and Outlook 2010 (lots of important subfolders) to a brand new SSD with Win 7; at the same time want to drop Outlook and transfer it all to Thunderbird. So far, following blogs and u-tube, my attempts were unsuccessful; I wasted long hours . I am fairly good user but I am definitely not an IT tech. Hoping somebody can give me a very detailed step by step guidance. Thanks Rad.

Install Thunderbird on your OLD drive, which you have started the machine using. Run the import wizard. It will offer to do it on installation. (it is on the tools menu (alt+T if you have missed that boat)

Then move you profile folder from one drive to the other once the import is completed. Thunderbird import from outlook was disabled for some years, but it has now been fixed and reenabled.

Anything to be imported from Outlook must be "in" outlook. PST/OST files that are not loaded do not get imported. The import is from Outlook the application, not the files it creates.

On the OLD DRIVE (which you have booted from so it will be C:) Windows key+R Type %appdata% press enter Copy the Thunderbird folder shown to a USB drive as an intermediary.

On the NEW DRIVE(which you have now installed as the C: drive and booted from) Windows key + R Type %appdata% press enter copy the Thunderbird folder from your USB media to the new drive replacing the Thunderbird folder you will already have, or creating a new one if Thunderbird is not installed on that drive yet.

Start Thunderbird. If the copy has been placed in the right place and you have all the files you outlook mail and accounts as well as contact will be in Thunderbird.

Note that it is good practice to right click the Thunderbird folder after each copy and in properties check the number of files and folders is the same. as you had before. Disk space used may well change due o different block sizes, but the number of files and folders should be constant.

Your best bet may be to install TB on the same drive that currently has Outlook and run the import wizard. Don't choose 'Import Everything' as it doesn't work - choose 'Mail'.

Using MailStore Home as an intermediary has also been successful:

After the Outlook data is moved to TB, copy the Thunderbird folder to the new drive:

Question owner

Once again I carefully followed the instructions (copying Thunderbird profile to external drive and then to the new ssd that replaced the old one ) - actually repeated it twice, to no avail. I could see data being transferred to that new drive drive but when opened Thunderbird, there was nothing. So, where did the data go? Is there a way to transfer directly, by connecting the removed old drive via USB? Thunderbird is installed on the new drive, just needs a profile to be assigned to it. Please keep in mind, I am not a savvy young (ish) IT person. thank you. Rad.

The transfer saga continues . There is probably something wrong with the backup on the external drive. After maaaaany attempts I finally managed to paste the profile from external to newly installed Thunderbird on the new internal drive. Once Thunderbird opened, I realized that only some, no more than 30% of folders visible on the old original drive showed up on the new install. New mails keep coming in just fine. Is there a way to check/open the backup drive to see what actually got transferred to it from the old drive? Could the missing folders be somehow "transplanted/added" if not found on the external backup? thank you for any hints...

Did all your Outlook mail on the old drive get imported to TB on the old drive? What is the size of the Thunderbird folder on the old drive? Is the size the same when you copy it to the new drive? If it's the same, you should see the same setup on the new drive as on the old one.

Out of deep frustration after failed attempts to transfer all data I decided to wipe the hard drive clean and install Windows and Thunderbird anew. Then pasted the Thunderbird file from external backup. Bingo, it worked this time, all folders showed up.
