I have about 1500 users i need to modify attributes for, so we can merge them with Office 365. I want to use the powershell to do this. I need assistance creating the proper csv file and help with commands to run in order to update the following:
MailNickName = email@example.com
proxyAddresses = firstname.lastname@example.org
I am not sure I have the proper field names, so feel free to correct.
I would like to experiment with a single sub OU before applying it to all users.
