I have not been able to test this combination and looked at the compatibility matrix but didn’t find my answer.
The customer is creating a new workstation build with Windows7 and wants to include viewmail in the build. The matrix shows that they will need to use ViewMail 8.x for Windows 7 (exchange 2007). This customer is currently using Unity 7.x and has no immediate plans to upgrade the servers to Unity 8x
I realize viewmail is usually backwards compatible however due to the differences in the workstations builds (XP v/ Windows7), I’m looking for clarification / confirmation that Viewmail 8.x on Windows 7 will work with Unity 7.x. If not, can they install viewmail 7.x on the Windows7 build?
