Q:  Can I recover deleted items from Thunderbird?Additional account settings

A: It is recommended that you configure your Thunderbird account to move your deleted messages to the Deleted Items folder on the server (webmail).  This setting allows you to recover deleted items.

Q: Can I use webmail for both my Thunderbird and my Office 365 mail?

  3. Click your @NU account name to display the Thunderbird main window. Under Accounts, click View settings for this account.
  4. In the Accounts Settings window, click Server Settings in the left panel. In the Server Settings section of the window under When I delete a message, select Move it to this folder, and then choose the Deleted Items folder on the server.
  5. Click Copies and Folders options in the left panel and make the following changes:
    • When sending messages automatically, place a copy in: Select Other and choose the Sent Items folder on the server.
    • Keep message drafts in: Select Other and choose the Drafts folder on the server.
  6. Click Junk Settings in the left panel.
  7. Uncheck the box for Enable adaptive junk mail controls for this account.
    NOTE: Server side junk/spam filtering is already enabled for Office 365 accounts.
