I found this simple to install and it works well. There are a couple of things missing that would be good, but excellent value for the price.
To be clear the things I consider to be missing are as follows and I believe only really highlight that this is a new product:
No Central contacts/email search/list - you can search for a contact/lead/etc. from and email but there is no general search for a contact to create a new outgoing email within Outlook.
No Attaching to a Case (or creating a new case).
The plugin doesnt appear in my mobile (iOS) Outlook - I know this feature is a possiblity but its not there (I wasn't actually expecting it to be, but the mobile outlook has the capability and other plugins can provide it).
I installed this to use with an email based support system. Fed up of just receiving emails (that tend to get added to Junk or Clutter) I wanted actual notifications. Along with the PushBullet app (which needed a bit of fiddling - more than this plugin) this now provides exactly what i want - Push notifications and pop ups when I get urgent support queries.
