Empty messages that cannot be deleted on webmail only

Hi,
I have a found, that only in one specific folder (with reports from firewall) I have like over 200 empty e-mail messages, with no sender, receiver, subject, date, size, even when I want to check source, it’s empty and these messages cannot be deleted. What’s weird, I can only see them over webmail, when I check this folder from cell phone, or Outlook, it’s not there. Can it be some corruption in file system, or how to get rid of it?
I use 10.3.3.53 version, but it’s there a bit longer, couple updates back, but I don’t know when they showed up, because I didn’t use webmail as often as now.

Anyone had the same issue? Thanks for help

Hello Asterix,

Please review this KB and use purge option if you like to remove corrupted messages.
