issue caused by wrong email address saved in autocomplete

We had email account
Say: for User A

Email address:

Now i have added alias email address for User say " and set it as primary email address.

I have transferred "" email address to "User B" whose display name is same as user A.

Now users who have been emailing "" from outlook, if they email "", it goes to """. I tried deleting  email address from autocomplete from one of user's outlook which fixed the issue for that particular user. So, i know it is causing by cached email address/autocomplete in outlook.

My question is,.. is there a way we can resolve this issue with out clearing autocomplete email address from each user's outlook. ????????

I think that you have to do this per user. You can clean only one address on the list. If you want clean all you can run Outlook.exe /CleanAutoCompleteCache. You can use it on logon script and clean for all users when they login. PS script may look like this
Start-Process -FilePath 'C:\Program Files (x86)\Microsoft Office\Office15\Outlook.exe' -ArgumentList '/cleanautocompletecache','/recycle'

AFAIK Olgierd is correct, this is something you have to do for each mailbox individually.
