I have modified two files for branding our OWA in C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.0.639.21\themes\base\
After replacing the existing files with the two new files, my changes do not take affect. I have cleared my cache. Still nothing. I did notice that our OWA change from:
C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.0.702.0\themes\base\
C:\Program Files\Microsoft\Exchange Server\V14\ClientAccess\Owa\14.0.639.21\themes\base\
and I don't know why. When I made the changes in 14.0.702.0 the changes were successful and I could see them immediately. Is there a service I need to restart? Also does anyone know why it would have changed from 14.0.702.0 to 14.0.639.21?
