Are you an Executive Admin?
As in, do you administratively support a boss and/or a team of folks?
In that case, you should have a central location (aka website) where all members of the team (boss included) can access files and information.
Now of course, I personally recommend SharePoint to do this :-)
You should create a SharePoint site to house any and all information that folks on the team will need.
I actually have three tips for what things you can put on this site.
1 - SharePoint Lists (instead of spreadsheets)
2 - Event information (from a group calendar)
3- Link(s) to important MS Teams
