I have created an AD account (Bobt James) + exchange mailbox (SBS 2011) with incorrect Firstname. I have updated and it has shown correct first name (Bob James)
Recently we have migrated our exchange to office365 and uses Dirsyc to sync our AD account when we do the initial setup.
When i go to O365 admin console, find Bob James it shows email address alias Bobt.James@XXus.onmicrosoft.com
When i go to Exchange Admin Center and find Bob james > edit properties > email address > i can see there is SMTP: Bobt.James@XXXus.onmicrosoft.com and i'm unable to delete it since the object syncs from on premises organization.
How do i delete this? I go to Attribute editor for this AD user using ADSIEdit, i could not find any entries. Where else can i find it?
