Ah, ok...so you want to copy the contacts from (as an example) User1, to the local contacts of User2, User3, and so on, right?
Are you using D365 or any kind of a CRM that might do this already (wishful thinking, but thought I'd ask)?
How many users do you have and how often do you want to do this?
I imagine you could have Flow watch a folder for a csv (which you've exported from wherever), and when a new file is uploaded, maybe it triggers a PowerShell script to import that csv into each user's contacts folder
- import-contactlist -csv -csvdata ([system.io.file]::readallbytes("c:\test.csv")) -identity (where identity is the username being copied into...so you'd need to either run through each user using whatever the new-fangled equivalent of a FOR-NEXT loop is (am I showing my age?), or have a script with each user listed in succession.
What do you think?
If that doesn't sound fun, let us know and maybe we can come up with something else.
Thanks!
