After the last update I lost all my e-mails. Only the shells were left. Took advice from the forum and repaired the folder. Started again, since then it has been impossible to delete any e-mails. Am reduced to checking mails on my phone before opening my e-mail account. Forgot this morning and now I have a malware e-mail in my box (not opened of course) but I can't delete it.

Have tried this file repair method but did not work.
