Sometimes Thunderbird may not load all folders from the email server after adding the account. In that case, you need to subscribe to them manually.

1. In the left folder panel, right-click your email account.
2. Select Subscribe…
3. In the “Select the folders to subscribe to” list, tick the folders you want to display.
   The essential system folders required for correct functionality are:
   • INBOX
   • Drafts
   • Junk  Email
   • Sent Items
   • Deleted Items
4. Confirm the selection by the OK button.

Since Outlook uses different names for some system folders (e.g., Thunderbird’s “Trash” folder corresponds to “Deleted Mail” in Outlook), you will need to manually map these folders in Thunderbird. This will prevent the Thunderbird from creating its own folders or using unsynchronized local folders.
Note: A correctly mapped system folder in Thunderbird is indicated by a special icon representing its function (instead of a generic folder icon).

1. In the left folder panel, right-click your email account.
2. Select Settings.
3. In the left panel, go to Server Settings.

Setting the Sent Items, Archive, and Drafts

2. Select Settings.
3. In the left panel, go to Copies & Folders.
