I'm using x64 Linux Mint 13 (Maya), which is based on Ubuntu 12.04 (Precise). The current version of Thunderbird installed is 17.0.2. My goal is to archive my messages into custom folders that are a) separated by month, as shown:
and b) stored in my Gmail account, not in the Local Folders are of Thunderbird. However, the Archive Options are greyed out unless I select Local Folders, as shown:
On a different system, one running Ubuntu 12.04 x32 itself (not a Linux Mint derivative) and running Thunderbird 17.0 (not 17.0.2) the Archive Options button is not greyed out and I can set monthly folders as an option. Archiving works properly, and the monthly folders are created automatically.
How can I archive my emails to these monthly folders in Thunderbird 17.0.2? Using Gmail's All Mail folder is not an option in Thunderbird because that folder in my gmail account has hundreds of thousands of emails, and enabling it in IMAP slows the program drastically.
