Is it possible to lock some emails so that we don't accidentally delete them? I know that I can put star and mark as important and create search criteria in such a way that no starred message or important or messages marked with certain label are not returned, but I'm curious to know if it is possible to lock or prevent some messages from accidental deletion.
I use Gmail for most of my email communications. Hence, I have hundreds of emails. Sometimes I get a feel to cleanup my inbox and try to delete them by searching by some criteria. However, there are times I get some important emails in the search results and accidentally delete them. I only realise this after few days/months and have no way of getting them back.
