File and folder selection
All our products are designed to automatically detect the location of the source data files of corresponding programs. However, if the Thunderbird to Outlook converter software fails to detect the path to .msf data files and mailing list automatically, there might be an issue. For starters, there might be conflicting profiles, identities, corrupted registry entries, or other minor issues that are making auto-detection impossible.
However, this is not always possible. However if Thunderbird to Outlook Transfer utility fails to detect the path to *.msf data files and mailing list automatically, this may be a sign of conflicting profiles, identities, a registry corruption issue or another minor issue rendering path auto-detection impossible. It will also happen in situations when you have multiple Identities or Thunderbird data files are copied from another system – that is, when Thunderbird has never been installed on the user’s system.
In case the program fails to locate your *.msf emails automatically, click the “…” (Browse) button to open the standard Windows folder selection dialog and select the source folder manually. By default, Thunderbird stores emails in a profile folder located here:
C:\Documents and Settings\%USERPROFILE%\Application Data\Thunderbird\Profiles\XXXXXXXX.default\Mail\
OR
C:\Users\%USERPROFILE%\AppData\Roaming\Thunderbird\Profiles\XXXXXXX.default-release\Mail\Local Folders\
Where %USERPROFILE% is your username, and XXXXXXXX is a sequence of arbitrary characters.
Please note that the “Application Data” folder is hidden by default and will not be visible in the dialog.
To make hidden folders visible, do the following:
- Open Windows Explorer (Ctrl+E) , click on “Organize” and select the “Folder and Search Options” command from the menu.
- Switch to the “View” tab
- In “Advanced settings”, find the “Hidden files and folders” node and expand it
- Enable the “Show hidden files and folders” radio button
- Uncheck the “Hide protected operating system files” option
- Click OK.
Doing this will unhide hidden folders and allow you to select the one containing Thunderbird source files in the manual mode.
IMPORTANT: Please bear in mind that Thunderbird to Outlook Transfer tool is capable of detecting the main Thunderbird profile location automatically if Thunderbird email client is installed on the same system. However Thunderbird profile may contain several Identities and Account records. In this case it is required to select the proper source directory manually. For multi-identity configuration we recommend to process each email account separately. Thunderbird to Outlook Transfer program can extract and convert data from damaged mailbox files of all supported formats and import them into 2010, 2016, 2019 and earlier versions of MS Outlook.
While working on Thunderbird to Outlook conversion software, we pursued the goal of automating as many complex operations as possible, and we’ve got most of the process covered by our tool. Your role is restricted to making a couple of simple choices and confirming your selections. You have three options: direct Thunderbird import to Outlook, saving messages to a new standalone outlook PST file, or extraction of Thunderbird mail to EML files The first scenario is fairly self-explanatory, while the second and third allow you to copy the resulting file(s) to any type of drive or cloud storage or transfer it to another system.
Alternative Scenario
If you still have the Mozilla Thunderbird installed at your computer, you may use menu Options | Account Settings | Server Settings to check the location of the email message store. The value of the field “Local Directory:” is what you need.
- Locate the email files
Run Thunderbird and click Options > Account settings - Click on Server Settings
On the next page, click on server settings. On the Local Directory part, you will see the location of your Thunderbird emails.
Prior to starting the conversion
When you delete or move messages from one Thunderbird folder to another, the source mailbox file remains unchanged as the original message is simply marked as deleted or moved and becomes hidden from view. In order to correct the message indexing and optimize space occupied by the mailbox files we recommend to “compact” Thunderbird folders before you start the conversion.
- To compact a single folder, right-click on the Thunderbird folder name and select Compact.
- To compact all folders, select menu File > Compact Folders.
Compaction progress will be shown in the status bar.
Saving emails from Thunderbird to a standalone PST file on your hard drive
If you want to convert Thunderbird emails to Outlook PST format ( .msf to .pst ), but don’t want to export them to Outlook right away, you can save the files to a PST format on your HDD for future use. The Thunderbird to Outlook Transfer software will still require Microsoft Outlook to be installed on your system to convert thunderbird emails to outlook PST files.
For successful PST conversion follow these steps:
- Download Thunderbird to Outlook Transfer software
Download and install the latest version of Thunderbird to Outlook Transfer software on your PC. Installation normally takes less than a minute and does not require any additional components or libraries to be downloaded. - Check your Microsoft Outlook Version
Simply open your MS Outlook software, click on file > Select Office account and click “About Outlook”. This will help you find out the version.
- Run the Thunderbird to Outlook Transfer Software
If your MS Outlook edition is 32-bit, you have to use the shortcut which launches the 32-bit conversion utility, otherwise you have to run the 64-bit tool. Both shortcuts became available at your computer desktop after the installation.
- Locate the .msf files
The program should automatically detect the location of the source *.msf and mailbox files. If it doesn’t, click on the “…” (Browse) button and select the necessary folder on the hard drive (see “File and folder selection” for details). You can also use the File->Open command.
- Run the Folders Scanning
Click the “Scan Folder” button (Find Storages button in old software versions), the program will show a list of available folders (email containers) in the large text area in the center of the program window. You may deselect there a folder(s) which you do not want to be processed, for example, to skip the Inbox emails, you may uncheck the Inbox container.
- Choose a proper Mode
On the top menu bar click on Mode and select “Save to PST File” mode. - Close Mozilla Thunderbird
Exit Thunderbird if it is still launched. Click on “Save“. The program will prompt you for a folder that the resulting PST file will be saved to. Select the location to save the PST file and confirm to save.
- Conversion Complete
Wait until the program has finished processing all the files. Full details about the items being processed will be shown in the log window.
The resulting PST file can be immediately copied to another system and loaded to Microsoft Outlook using menu File -> Open -> Outlook Data File…
If Thunderbird is not installed on your system, you can still use Thunderbird to Outlook Transfer software. Just copy the Thunderbird data folder from any other system and convert its content into a PST file. Copy the PST file to the destination system and load it in Microsoft Outlook to access the converted emails.
