This is done with a click on File > Compact Folders. If you do not want deleted messages to be imported into Opera, compact the mail folders before you start the import.If you are using a setting where only the header is downloaded, only that header information will be imported into Opera.
Make sure all messages are downloaded to Thunderbird completely.There are a few things that you need to make sure of before you start importing messages: Once done, select Opera > Settings > Import and Export > Import Opera Contacts, and select the address book file from your local directory. You can use this web service to convert the comma separated listing into a format that is supported by Opera. In the address book listing, select Tools > Export, and select comma separated in the save dialog.
In Thunderbird, click on Tools > Address Book. To import your Thunderbird contacts into Opera you need to first export the address book in Thunderbird, then convert it into Opera's format, before you can import it into the mail client. Who would want to switch to a desktop email client that can't import old emails, the accounts or addresses?Ĭontacts were not imported by default, and Opera itself only seems to support importing Opera Address Book files. This is without doubt one of the most important factors.
