For several years, I’ve encountered an issue with Dell OptiPlex workstations related to the Dell wireless keyboard, often overlooked during quoting. Occasionally, clients report unexpected email deletions in Outlook, with messages moved to the Archive folder. This happens when the backspace key is triggered, which can be disastrous.
After searching online, I found a Dell forum thread confirming multiple reports of this issue with the wireless keyboard. One plausible explanation is debris getting stuck under the backspace key, causing it to activate unintentionally.
While some speculate wireless interference, it seems more likely that the design, specifically the spacing between keys, may allow debris to lodge under the backspace key, causing it to remain stuck.
Unfortunately, there are no concrete fixes yet. You can read more in the thread here: Random deletion of text | DELL Technologies
