The family admin can see all of my recently edited files on his computer when I store them...

Dear Charles,
<br />thank you so much for your help. I must update the given information a bit: When I posted this, I thought that only two docs were affected, but in reality there a more - yet, by far not all of them. I can open others, that are filed on that same external drive as well (in the same folder or in others), without any issues. All of them are docx.
<br />I worked on two of them on Dec 9 the last time with Word Microsoft 365, and all was fine. I sent these docs via email back then, but when I try to open them in that email, the same error message appears.
<br />Strangely enough, these docs can be easily opened by another email recipient (android), who tried to file it under a different file name and then sent it back to me, with no positive result, unfortunately. Just now, however, I decided to send the docs to another email address of mine, where I could open them and add a small modification, file them in the cloud and send them back to my inbox - and, gladly enough, it worked, I can open the documents without any issues. What on earth is the issue???
<br />Cheers, Denise

Hello George,
<br />thank you for your quick reply and your kind words.
<br />Unfortunatley, the information in the link you provided, did not help me.
<br />There are no restrictions on the account of my son. I am just unable to remove him from his "organiser" role within his Family settings - there is no button, menu entry or anything else.
<br />Within my own profile i can opt to leave the family (in the menue right next to my profile picture)
<br />This option is not available for my kid in his family settings.
<br />HELP ..please.....
<br />

Unfortunately not for a batch of files. Individually when double clicking the header or the footer it will edit all of them but of the same file.

Thanks

And then everybody can add his file with a link and can edit it from the browser? Or can just I use my own files?
<br />Edit: I don‘t want to sign in. I just want to use the share link

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
