Hi!

if syncing a single user everything works. when syncing all users with DIRECTORY flag i got the following error:

ERROR Failed to Sync-ContactList for user@mydomain.com Failed verify that MY COMPANY contacts exists for user@mydomain.com

also getting 404 and 503 errors

Does the account you're running it from have Exchange application impersonation permissions? Even with an admin account, you need this.

Yes, the account has application impersonation rights. Found out if i run the script at 9:00 everything works fine. if i run the script at night at 2:00 i get 404 or 503 error on every mailbox.

I think its a microsoft thing

Can you verify that the necessary Office 365 URLs are whitelisted in your environment? All Microsoft 365 Common URLs with ID#56 on the following page should be allowed: https://docs.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide
