M365 Subfolder Contacts

[DoubleHSystems]

Hello everyone,

I have a problem with a customer where I need all the contacts from subfolders of a single mailbox in the global 3CX phone book.

So, I have a mailbox called [email protected], and there are about 15 subfolders with contacts there. (Almost 3,000 contacts)

And I need exactly these contacts from all subfolders to be available to all users in 3CX.

Thank you in advance.

Addendum: It is about an M365 mailbox

Contacts need to be in the root folder, no subfolders.

Thank you for your answer.

Can I do it through public folders?

So I create a public folder for each contact folder?
