Can I use newtwork storage for Thunderbird message store reliabily?

david replied

Considering migrating from Outlook to Thunderbird (TB), as it is a logical potential path. Best I can tell from AI input is placing my message store on a network share (colocated, stable network), would likely be unreliable. Said that TB storage format was basically fragile and subject to corruption if there was any kind of hiccup in the data transfer or if something happened during a power outage for example. Wanted to see how the real community felt about that and if it was indeed inadvisable to do so.

As you stated, it's not a Thunderbird issue, but a network issue. Again, as you stated, hiccups happen. My advice in such an environment is to copy first, delete later.

Copy what? Not following you.

Copy files to new folders, not move to new folders. Thunderbird is only a messenger in the network, having no power there.

Still not sure we are on the same plane. I am talking about what I'd call the "message store" where all the emails are stored. I gather that is in mbox format as the Maildir format is not ready for prime time. I'm not copying files or folders per se, I'm just receiving mail.

You're right; we weren't. I agree, for mbox files, that doesn't look stable. I have no experience with maildir.
