Campbell IT 4 Posted December 18, 2018 Share Posted December 18, 2018 Hello, We currently have Mail Security for Exchange version 4.5.10023 on our Exchange 2013 servers. Do I need to uninstall version 4.5.10023 first, or can I install 7.0.10022.0 over the top and have it automatically uninstall the old version? Thanks.

Administrators Marcos 4,841 Posted December 18, 2018 Administrators Share Posted December 18, 2018 I would strongly recommend uninstalling v4 completely, otherwise settings will be preserved which may cause issues with HIPS. Link to comment Share on other sites More sharing options...
