When an email is attached to another mailbox it shows old contact information in exchange, sharepoint, and skype

Hi,
We've recently noticed a problem that started happening.
We have former employees who's emails are attached to another users mailbox so that they can get the emails the former employees. Because our policy states that their mailboxes must be removed and archived.

The users will turn into the former employee in Skype, and Exchange, even though the email used is the correct email. while in SharePoint if you hover over them it shows the proper user name but the contact is the other users information.

Is there anyway to fix this? we have tried applying patches and updates. It might have been happening before but recently we have had a lot of departures.

What do you mean by "employees who's emails are attached to another users mailbox"?  Do you mean the terminated employee's email address is saved as an alias to the current employee on the Exchange server?

I've seen a similar issue with what was back then called Lync.  It was related to personal contacts saved in the current employees' instance of Outlook.  Search the contacts and see if you can find any entries for the terminated employee and delete.

Yes, basically when the employee leaves the address gets attached to their managers mailbox as an alias for them to take care of what ever they were doing and re-delegate work.

Also yes, removing the contacts from outlook, solves the issue for one user, but when its a whole company this becomes tedious and extremely time consuming and was tasked for finding a better solution.
