I had it showing on bottom what each account had reached 1% or 50% and when the "web master' left I was stuck learning how to do Thunderbird with no training. I have no clue what happened but one day the quota bar was showing what each email account had and then poof gone. I believe we had to set it up in a CPanel webmail for Go Daddy account that handles our web site but I cant figure that out let alone how to get Thunderbird to show each accounts quota. I downloaded the add on "display quota" but it still isn't showing up. It says this and to do this: - It will only work if your mail server has an IMAP quota set: right click on your inbox, then in the "quota" tab of the properties, if a quota appears, you're good

so I did it and it has nothing in it? What it says is "There is no storage quotas on this folder. So I am guessing the downloaded add on wont work so I am back to square 1. I need help because if I go past my quota Go Daddy will charge me. Thank you Debra
