Migrating your email from Mozilla Thunderbird to Office 365 can be done in a few steps. Here's a general guide on how to do it:

 IMAP Sync

This method involves setting up your Office 365 email account in Thunderbird as an IMAP account and then copying your emails and folders from Thunderbird to Office 365.

Configure Office 365 Account in Thunderbird:

Open Thunderbird.
Click on "File" > "New" > "Existing Mail Account."
Enter your Office 365 email address and password.
Thunderbird should automatically detect the IMAP settings for Office 365. Follow the prompts to set up the account.
Copy Emails:

After configuring your Office 365 account in Thunderbird, you should see both your Thunderbird account and Office 365 account in Thunderbird's sidebar.
You can now select and copy emails and folders from your Thunderbird account to your Office 365 account by dragging and dropping or using the copy/paste options.
Synchronize:

Allow some time for Thunderbird to synchronize your emails with your Office 365 account. The time it takes depends on the amount of data you are transferring.
