Daniel, I am sorry to inform you that I was getting crazy in Evolution trying to find some messages. Using the "Search in all accounts" I can find the messages but not if I only search in the folder where the message is (you can check that in the previous search in all accounts).
Finally I remembered this problem, go to View->Show hidden messages, and then all the messages appeared in my folder another time. I think I am sure some users will get crazy with this issue: the Search field in the main view in the email that in some way filter the messages with the field empty. -- Messages in Inbox are hidden after using new search engine https://launchpad.net/bugs/67709 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
