[Migrated from MSDN Exchange Dev] copy outlook contacts from 1 user to 1000 users

Question

[Note] This thread was originally posted on MSDN.

[MSDN thread link] copy outlook contacts from 1 user to 1000 users

[Original post]
Assuming I have a mailbox with 4 contact folders, these folders have to be exported and imported to 1000 users so they have the same contacts with me.

It is easy for 1 or 2 users, i could have export and import. But we are talking about 1000 users. are there any tools out there that can help me on this?

Answer 1

If you need the contacts available by that many users, store them in the GAL. If storing them inside individual mailboxes is a must, you can use EWS/Graph API to copy them between mailboxes programmatically. Or adjust the default permissions so that anyone in the company can access them, as already suggested above.

Answer 2

Hi,

are there any tools out there that can help me on this?

To the best of my knowledge, I am afraid there is no official recommended tool for this requirement. That being said, instead of manually exporting/importing the contact folders, personally I would like to suggest sharing the contact folders with the other users so that all the users can use the same contact folders.

1. In People, select the contact folder you would like to share, go to Home > Share > Share Contacts.
2. In the To field, enter the recipients for the sharing invitation message, you can select the checkbox below if you want to grant the recipients with the edit permissions.
   

If you are going to share the contact folders to all users in the organization, you can right click the folder, go to Properties > Permission, change the permission of "Default":

Here is an official article for your reference: Share a contacts folder with others
