HI,<br />
I recently moved my thunderbird profile emails to another folder. <br />
I followed the online instructions and it all went well. However <br />
now when I open Thunderbird, I can no longer see my Calender <br />
nor my Tasks that were previously visible. Any idea how to get them back?

HI,
I recently moved my thunderbird profile emails to another folder. 
I followed the online instructions and it all went well. However 
now when I open Thunderbird, I can no longer see my Calender 
nor my Tasks that were previously visible. Any idea how to get them back? 

Calendar and Tasks have disappeared from Thunderbird

Thunderbird is an email, newsgroup, news feed, and chat (XMPP, IRC, Twitter) client that supports POP and IMAP and LDAP address completion. The vanilla version is not a personal information manager, although the Mozilla Lightning extension adds PIM functionality. Thunderbird can manage multiple email, newsgroup, and news feed accounts and supports multiple identities within accounts. Features such as quick search, saved search folders, advanced message filtering, message grouping, and labels help manage and find messages. Thunderbird incorporates a Bayesian spam filter, a whitelist based on the included address book, and can also understand classifications by server-based filters such as SpamAssassin. Extensions allow the addition of features.
