The IT NoHelpLine

I work for a large architecture firm. As anyone who works in the field knows, it's easy to get yourself in trouble if you don't keep a paper trail of everything you do. So for the last 2 years I've been filing all my important incoming and outgoing emails in a "cabinet" on our office email network. I've accumulated several thousand emails, all sorted into their appropriate folders and subfolders, and I reference them on a daily basis for one thing or another. To give you an idea of what's in there, it includes:
--Projects I'm currently working on / tasks to complete
--Old projects that I use for reference
--Office information, in case I need to look up where Joe Smith sits or what codes to bill on my timesheet

Suffice it to say that I have a lot of extremely important information in there. So you can imagine how I almost keeled over in my chair when on Friday I opened up a folder and ALL my emails were GONE. For the next five minutes I panicked, opening folder after folder as though the emails might sense my distress and reappear. Finally I came across my Trash folder, which to my shock (and great relief) contained 3300 emails...everything that was missing. Then I looked at the deleted date, and that's when my relief turned to anger. They were deleted at 2 am on 7/1, the Saturday before, when I was not even remotely near the office. It seems that our brilliant IT department had decided to run some kind of cleanup over the weekend, with no prior warning, that deleted every email over a month old. WTF?? So I angrily spent over an hour re-sorting my emails back into their folders. I managed to clean some old junk out along the way and ended up putting about 1800 emails back into the cabinet.

It didn't end there. First thing Monday morning, guess what...there were 1800 emails back in the Trash. Apparently whatever the IT department did is deleting the emails on a daily basis. I spent about 30 minutes dumping them back into the correct folders and then sent a complaint to the IT Helpline. This is sort of an email forum where you can ask a question and the IT people (supposedly) will get back to you. Well, by 4:45 today I hadn't heard a peep from them so I marched myself over to their office, where the last IT guy was just heading out for the day. I asked him about the lack of response and he brushed me off with an "Oh yeah, that's on my list to come talk to you tomorrow. " Nice. So once again I spent 30 minutes sorting my email, knowing full well that they'll be back in the Trash tomorrow, because I'm terrified of what will happen if I leave them there overnight. I really don't have time for this crap. Thanks for nothing, IT jerks.
