One of my user in AD has changed her name due to marital caused, therefore her previous AD name was DOMAIN\JJane changed into DOMAIN\JHenderson
The problem started when she got assigned to send email as HR@domain.com, it is not possible no matter what I tried before and wait for more than one week.
I've granted her Send as permission from Exchange Server 2010 SP3 management console Full Access and Full Send As permission, I've checked that in AD Users Account and Computers, her newly renamed AD account has got Send As permission checked.
So how do I enable her to perform Send As from her Outlook 2010 as HR@domain.com email ?
Note: I've tried with other username that hasn't changed, it works after 2 days
Exchange Server 2010 SP3 on premise
