How can I be sure that I can access an email that I deleted in the last couple months if needed? I get this message whenever I open TB "The messages you have deleted can be purged from disk. This operation will save about 1.6 GB [it was 395 MB until I started deleting a lot of email] of disk space. Select the option below to let Thunderbird do this automatically without asking you." I am reluctant to allow TB to purge deleted email automatically. Under my Inbox folder I recently created an Archive folder an other folders where I put email that I know I want to save. However, sometimes I delete an email and then realize that I should have archived it. When I look in the Deleted folder under the [Gmail] folder I see older and newer email but I don’t always see the email I am looking for. The Important folder also under the [Gmail] folder keeps some email. I don’t see a clear pattern to which emails are saved in these two folders. I have TB 78.6.0 32 bit with updates installed automatically.Here are some settings that may be relevant. Account Settings - Server Setings > Server Name is imap.gmail.com: Junk mail is moved to the Spam folder, Enable adaptive junk mail filter logging is not checked: Disk Space > Always keep starred messages is checked. Options - General > Disk Space, cache currently using 762 MB of disk space, Override automatic cache management is not checked, Compact all folders when it will save over 200 MB in total is checked. Thank you for any help you can offer.
