We recently installed Cisco Unity 8.5 and everything is great except for the voicemail to e-mail feature. When you click on an e-mail that comes from the CallManager with a WAV file attached containing the voicemail, it locks up Outlook for anywhere between 30 seconds and 2 minutes. This is true for both Outlook 2003 and Outlook 2010.
This problem doesn't occur with OWA or when playing the attachment through an iPhone, iPad, Blackberry, etc., it is just when trying to access the e-mail through Outlook. This is true whether using the Cisco VMO tool or not.
We are running the latest version of Kaspersky for anti-virus. I have worked with Kaspersky to adjust settings to ignore these files, but this has not worked, and if I just disable Kaspersky the problem still exists.
