What shortcut might archive messages on outlook.live.com?

The fact is, I never actually use an app, but the outlook.live.com website. I don't have shortcuts disabled. When I was addressing this with the support team, I typed E multiple times in reply e-mails, which was not in caps lock, but shift e. I found that in my case, e-mails were disappearing seemingly when I possibly was typing the key of e with keys that were next to it with the same finger on accident. If I did accidentally press he shift key with my pinky finger, I am not aware of it. But it would be strange that pressing shift e multiple times to reproduce the issue when writing the e-mails to the support person did not make messages archived. Another thing, that is not a good shortcut. Imagine if somebody's name is Emily, Elisabeth, Edward, etc, or a street starts with capital e, or you need to explain something is East in an e-mail. This could be problematic, if capital e will archive an e-mail. One of the earlier respondents said that it only works when selecting e-mails, but you are saying it seems to work while typing an e-mail. For me, it doesn't seem to work. Are you using outlook.live.com, or the 365 application? Because it doesn't seem to match up that it is happening to you, but not other people. Also, their support team doesn't really help with this issue, as for me, they told me to turn off the shortcuts, use the onscreen keyboard, or attach a separate keyboard, saying that these help disabled people. I am not physically disabled, but i had accidentally touched other keys a few times, so i kind of found this a little irritating that they said this. I think that nobody who is good at typing, or knows how to type would like this suggestion. I don't want to peck on keys, or be told to use some sort of external keyboard, when mine works fine.

Could you be accidentally triggering 'sticky keys'? This can be done (if not disabled) by hitting the shift key 5 times in a row, and has the effect of 'holding' the shift key on for the next key stroke. I get an audible arning each time the shift is held, so one might think it would be obvious that 'something' was happening. In addition, I had to click 'yes' on a prompt after the five shifts before SK was turned on, so one might think accidental triggering was impossible.

Having turned sticky keys on, another 5 shifts turns it off (accompanied by a nice little 'tune'.

To stop SK from being triggered at all, go to Settings>Ease of access>Keyboard

Definitely not sticky keys causing the problem. I do type around 100 words a minute, so a combination of keys is possible. However, I can't seem to reproduce it when I type the same sentence over and over after it happens. No idea what is going on. That said, this has not happened in several months, so perhaps there was a patch that fixed it.

I noticed that when it happened to me most recently, I was not touching several keys next to each other. It could have been the shortcut, but I do not know. It still had happened randomly, and does not happen frequently. They also removed the "undo" feature, which was not there originally. I find it odd that I can't get any answers when I ask questions through outlook.live.com. They also keep asking me to produce PSR logs when I don't know what happened.

Happens constantly, I HATE IT!!!!!
