"Regarding the size mismatch, we will not be able to assist you from our end as this is beyond our support boundary. You may contact Thunderbird support team for further assistance. In our records, your account shows 8.63 MB used out of 5 GB." - the message I got from Zoho unable to explain the discrepancy in TB local inbox size.
I got 5 accounts, including 2 Zoho accounts, but the one in question is the most active so usually larger then others. However, I matched all the settings with other imap accounts, regularly delete messages and compact folders as my server size shows, but local inbox is not getting smaller. I moved the app from a 1G SD card to 32G card, but prefer to stay with imap. What's wrong? TB 184.108.40.206 on winXP system
