Dumbest thing user accused you for?

This was a while ago … when Blackberries were the new(ish) hotness. I was working for a pretty small company, with a single remote office. The CEO and CFO, both worked at HQ and had just gotten set up with their shiny new BBs. The lady who ran the remote office, not to be outdone by the CXOs, went and get herself a BB as well. But since she was remote, she had to set it up for herself. There was no exchange, MDM wasn’t really a thing at all. It was a classic IMAP set up. She did all of this without telling us. The morning after she got the device, she submits a ticket stating that her BB won’t send or receive emails, but her laptop was getting emails just fine. As you might expect, she immediately escalated to the IT manager. Since this particular user had a reputation of being not very nice, and quick to escalate to the CEO, the manager asked me to see if I could figure out what was going on. Being relatively new to the biz, I immediately assumed that it was weird config thing on the mail server or on the BB. I went through the mail server config and logs. I hit the forums for the mail platform, and I jumped on an IRC channel that had some of the support techs from the mail platform. After some “encouragement” from IRC, I reached back out to this user to confirm that she had in fact typed in her password properly. She insisted she had, and she even had someone else from the remote office type it in for her (‘twas a different time). I asked her to close Outlook on her laptop so it would stop syncing, and then power cycle the BB. My goal was to be 100% sure I had a log entry from the BB connection. As soon as I did that, I immediately saw the issue in the log. An important fact in this tale is that her username had 2 consecutive ‘n’s in it. And those BBs had tiny screens. Very easy to misread something. I informed her that she had in fact mistyped her username, which was first initial last name. Her reply was, “I most certainly did not. I know how to spell my own name. “ I told her that I was going to paste the log entry into Word, increase the font to 18 point so it would be really obvious that where there should have been ‘nn’ it was in fact ‘nnn’. I CCd the IT manager on the email with the log excerpt attached. Her reply was that I had manufactured the log to make her look stupid. (I didn’t need to work that hard to make her look bad, trust me) Fast forward 3 days. The CEO comes into my office asking why I’ve not helped this person get her BB working properly. I explained the situation to him, and showed him the Word doc. His response was, “You mean to tell me that she’s been complaining for 3 days because she’s convinced that there’s no way she typed in her username incorrectly? That tracks I guess.” The following Monday I get an email from her stating that she resolved the issue on her BB and mail was flowing as it should. In the end, the CEO had called her back and told to stop being stubborn and try the suggested fix. She never admitted she was wrong, or apologized for being so rude about it all. But it’s still one of my favorite tech support stories. I think it’s been right around 20 years since this all happened.
