Office 365 - Contacts

[Jean-Philippe_Bergeron]

Hello, I have a small project to sync contact that we have in a system to all the employes.

Right now, i'm importing the contacts to a generic account using Import-ContactList and Search-mailbox to delete each time because it's creating duplicates instead of updating the existing ones, and then I add the generic account to all mobile phone using our mdm.

It's working but it's really not the best...
Any way with powershell in 365 to EDIT a contact inside a mailbox ? that way I could manage it without having the delete everything before pushing the changes...

thank you!

If you want to share them with everyone in the company, the best place to put them is the GAL by creating a mail contact entries. Or if you don't want to clutter the GAL, something like a PF Contacts folder: https://www.cogmotive.com/blog/office-365-tips/create-a-company-shared-contacts-folder-in-office-365

If you insist on storing them in a mailbox, you will need some EWS-based script, such as the one here: https://www.allabout365.com/2010/07/using-powershell-to-import-contacts-into-exchange-and-outlook-li...

Thank you for your quick answer.

Yes GAL would be easy but with more than 1500+ employees, I need to push by departments or it will be too craazy...
I'll check EWS, I tough it was only for onprem not 365

Thank you again
