Once I delete a message, T-bird (147.0.4 on W11 Pro) begins compacting, and then I'm stuck until it's done. This is new behavior. Previously the system compacted occasionally, but now it's every single time I delete something from the inbox (which happens frequently during the day, of course, sigh).

Anyway, many thanks in advance for help/guidance and if it matters, I'm one of those who contributes monetarily for use versus freeloading. Also, no, we don't believe updating to the latest version is productive for our situation so I hope this is not the solutuion. -- Regards,

Hello everyone. Thanks for all your support.

A few weeks ago I started noticing a pop up window was occurring every (approx) 5 minutes in Thunderbird suggesting that I run a compact to save 992MB. I assumed this would stop happening after a few weeks and a few updates from Mozilla, but the problem has remained, so I'm coming here to ask about it.

Context: I'm on Windows 11. I have multiple email accounts that my Thunderbird reaches out to. At least one of the accounts is retired so reaching out to its historical server fails.

Reproducing: For me to reproduce it, I run the compact. Quit Thunderbird. Start Thunderbird. It reports 992MB can be freed. I let it compact. The main inbox disappears and reappears. I wait a few seconds and restart Thunderbird. It again tells me that it can save 992MB by running a compact.

What I've tried: I've tried repair on the inbox folder of the account I'm typically in. That didn't help. I have many other folders across many accounts and not tried to repair any other folders. I've searched the Mozilla help system.

Logs: It seems to me that a compact is probably failing but I don't know where to look for evidence of the failure.
