I logged into Microsoft OneDrive which I have done before but this time my thunderbird page changed with the Inbox reading 'Microsoft Inbox' and the tab for the Thunderbird Calendar and the one in the tools box have disappeared. How do I reinstate the Thunderbird calendar?

Kind regards Geoff

Go to the Add Ons page, the Extensions tab. Is Lightning listed there. If not type lightning in the search box and install it. If it is just disabled, enable it.
