I just lost over 5 years of 'saved as important' mails from my inbox thanks to the new system. Possibly as much as 7 pages worth. All I did was delete buff mails from a friend by ticking the box next to them as always and then used the 'context menu' to delete all. Next thing I know all I have in my mailbox are the guild coin payments for recent guild quests. Gone are all the maps I have made and saved in mail to send to guild members as and when they need them, gone are all the contact details of game friends going back well into 5 years, phone numbers, emails etc, also gone are all the links I have saved to websites with useful tips for guild members, add to that all the standard mails I send to the guild for events, to new members, hints and tips etc etc etc.
At no stage did I use the new 'collect and delete' button.
Fantastic work BB. I look forward to seeing if you can reverse the process but also know that if I mail support nothing will be done and after the first mail to them all I will get is the 'Oh you are trying to respond re a closed topic'' mail. Be good to see a BB sort this out in response to this thread but.....
