We have two single-sign-on (SSO) access areas to our current OWA email system within our luminis portal. One is the email icon and the other a channel box that displays a screen shot of the user's email inbox and acts as a link to it. Both when clicked give the user access to their email account.
Currently we are in the process of switching over to Office 365, but we are not moving everyone over at the same time.
Is there a way to modify the email icon and channel box to connect only those users switched over to the new Office 365 without interring with the email icon and channel box of those not migrated yet?
All help and words of wisdom is greatly appreciated!
