Second laptop erases in Onedrive my work from the last days on my first computer.

I didnot install office on my laptop. It had come with preinstalled office 365 apps.
I received the purchase confirmation from lenovo germany on my gmail id (which is actually from India)
I have actually used the student discount while purchaseing the laptop using my university email id to get discount and while billing I gave my indian gmail id.
I am using the same indian gmail id for logging in to my microsoft account for activating the office on my laptop. I also tried asking for help on lenovo support but they say to ask microsoft support to give product key or activation help. I also asked microsoft but I get no response.

Hi Antonio,
<br />thanks for your answer. I'm not looking for the iOS-Shortcuts.
<br />I try to explain my problem once more in English:
I have created my own shortcuts in MS WORD, f.e. command+control+r gets my characters red.
<br />For different reasons I created two accounts on my Macbook (iOS Big Sur):
<br />- The first one has an data immigration by Time Machine. But this produces a littel other problem, which is not off topic here. To fix this I create a secona account
<br />
<br />- The second account: All datas were put on there manuel from a second backup, so all the applications. That means the application are "fresh", without my individual created shortcut.
<br />-> My question is: Where does Mac OS hide these indidual shortcuts, so I can go into the system of the first account, copy that file and move it to the system of the second account.
<br />I thought to rember, that they are in the "hidden library". You can open it: finder menu -> go to + option --> then you look in the folder preferences for com.microsoft.Word.plist
<br />I found this file and some others with this beginning. I copied them and moved them into the same folder of the second account's system. But it changed nothing.
<br />I hope, I explained my problem better. Sorry for my English
<br />Ulf

Hello

I am , Independent Advisor, to work with you on this issue. You should create a new notebook in Onenote online and copy the sections there from these .one files (on a Windows computer). Then you can access these onenotes from your Mac also

.

if I could - instead of installing Win 10 and OneNote 2016 - just subscribe to Microsoft 365 to get access to my old OneNote files on my MAC? - This won't work.

Dear Augustine_E,

Thank you for your engagement in my case. There should be two answers to my problem message by me: The first of should be a screenshot, the second an all-clear signal, that the problem, a overloaded processor, is solved. It seems to have not worked accordingly.
I am so sorry.

dear Juliet,
<br />thank you for your answer.
<br />I started my PC on safe modus, but the problem was still there unfortunately..
<br />it happened for the first time yesterday, as I pasted some new diagrams from an excel to my word file but without these diagrams being linked to excel ..
<br />anyway, thank you so much..
<br />
