This is most likely due to the Global Address Book (GAL) in your Outlook isn’t updating. There are a couple of things you can try
Office 365 Instructions to Fix Error
To begin, go to the Send/Receive tab (Outlook 2010, Outlook 2013, and Outlook 2013) and select Send-Receive Groups > Download Address Book from the Send/Receive drop-down menu. The Download Address Book button is located in the Tools menu in Outlook 2007.
Then click on OK.
Now try sending again from Outlook using your shared mailbox or in the FROM address with a distribution list. Also, try grabbing the FROM address from the Global Address list instead of the GAL.
Close Microsoft Outlook and delete all of the files in the “Offline Address Books” folder. It will repopulate on its own.
It can be found here in Windows 7, 8.1, and 10:
If you are using outdated Windows XP, check the following path:
C:\Documents and Settings\Username\Local Settings\Application Data\Microsoft\Outlook\
To resolve error code 0x80070005 to MAPI E NO ACCESS or E ACCESSDENIED, utilise the Exchange Error Code Lookup tool. This means that the Exchange user must have SendAs access on the shared mailbox (the error still exists then try to add Send-as permissions using Office 365 web base admin panel). Execute the Exchange PowerShell command:
Add-RecipientPermission "HelpDesk" -AccessRights SendAs -Trustee "John Smith"
