Will I be able to access mail and attachments from Thunderbird once Yahoo account is deleted by admin.
Using IMAP I "backed up" (is that the right word) mail from my work Yahoo Business Mail account (george@sttheresaoakland.org). The contents of that account are now in Thunderbird under the same. The email administrator is planning to delete this account. What happens to those messages in Thunderbird then? I don't need Yahoo and Thunderbird to sync any longer but would like access to the emails and attachments via Thunderbird. Is there a way to change the account email address? Thanks.

IMAP mail accounts have a remote view of the emails on the server. You 'subscribe' to see the contents of server folders. Only the headers are downloaded and when you select an email the folder is copied to a temp cache to facilitate quicker access to that folder. These emails are not stored on your computer.
If you choose to 'synchronize' folders, then a copy of the folder is downloaded to your thunderbird Profile folder.
This means you can view those emails when in offline mode. These emails are on your computer, BUT as these folders are set to synchronize, it means that folder can get updated by the server, if emails are removed off the server and you synch, you will see all of those emails disappear from Thunderbird to synch and match the server.
So the best method is to synchronize the folder to get emails onto your computer, then go into 'offline' mode so that Thunderbird cannot connect with server. Then move those emails into suitable folders in Local Folders. The 'Local Folder' folders will be stored on your computer and will not be efected by the IMAP mail account even when you later select to remove it.
You can use this addon to create a backup of Local Folder folders and emails and also synchronised folders in offline mode.
Right click on folder in Local Folders (or a synchronized folder in offline mode) select 'Importexporttool' then you have a selection of methods available. see image:
