Hello, I have some questions about a particular Thunderbird installation. There is this company which uses a LOT of accounts (PEC emails, to be exact, something we have here in Italy) and they are all managed by the same Thunderbird instance. There are a lot of them, and I do mean a lot. More than 100 for sure. The PC is old, too. So what happens is, Thunderbird loses a lot of e-mails. The accounts are all configured as POP and for automatic download (at startup, every 10 minutes and so on) but even if you manually ask to download all messages, it won't happen. There's no error or anything, some folders just don't get updated. If you actually want everything to be downloaded, you have to manually browse account by account and download them for each account. I noticed the system takes a whole lot of time to just show the inbox folder on many accounts, minutes even. So I was wondering, do you thing there's a way around this? Like maybe archiving messages so that inbox folders aren't huge and full of messages? Any setting, anything that can make things more fluid, aside from changing the computer?
