We are rolling out a new Exchange server for a big client. The have mixed PC & Mac computers. We are also switching email domains in the process. The solution is to use profile switching to start fresh with the new server, & keep the old emails separate, but still functional. We can not do fast user switching, or have a separate user account on the computers for this. To our dismay, Outlook 2011 does not really support this. We are all attached to the same domain, & use AD. Not sure what we can do. Having both accounts active under one account is not going to wok for us. Does anyone know a 3rd party profile switch, or a work around to have 2 separate accounts under Outlook 2011?
