WDSEML is a Thunderbird searchable email file that the Mozilla Thunderbird client creates to help users in searching message content using Windows search. To know more about this file format, read our other article on WDSEML file extension.

Here, we will focus on the method to import WSDEML files to Outlook 2019, 2016, or 2013 in bulk. But, before we move onto the conversion method, take a minute to consider a few things beforehand.

Things You Should Consider Before Importing WDSEML to Outlook

Know that a WDSEML file is only a partial copy of your actual email message. They do not contain the data visible on your Thunderbird application. So, if you actually want to import Thunderbird emails to Outlook, then importing the WDSEML file is not the right way.

Mozilla Thunderbird stores its actual email messages in an MBOX mailbox file. It is a no-extension file having the same name as the mailbox it represents. For eg: the INBOX mailbox file contains all the emails you see in your Thunderbird Inbox folder. So, you will need to process these files if you want to move the ‘real’ emails.

WDSEML file is only useful when you wish to search for specific Thunderbird message content directly from your Windows search panel. It loses its significance in MS Outlook.

Furthermore, the WDSEML file does not have any attachments. So, don’t expect attachments in the output emails in Outlook after importing these files.

If you still wish to import WDSEML files to Outlook, please proceed with the article. But, if you want to get your actual emails in Outlook, opt for MBOX to Outlook Converter.

WDSEML files reside on your computer in the Profiles directory. To know its location, go to Tools menu >> Account Settings >> Server Settings and check the location in Local Directory.
