I have few requirements:
1. I have Primary emails created in O365: email@example.com
2. I want to export the list of all users in O365 with their Email addresses.
3. I want to create Alias's for all the user, which will be more than 1 e.g. firstname.lastname@example.org & email@example.com & firstname.lastname@example.org
In the above step there is a different Domain name also, i have the accepted domain already staged.
4. Also, I want to delete the .onmicrosoft.com for all users (if possible)
I would prefer if I can export the existing users in csv, then update different columns with Alias's & then update via powershell calling updated csv.
Thanks a lot in advance for your kind help.
