Hello,
we upgraded some clients: Scalix Connect 9.2.0->9.4.2. After update outlook failed with "UAL-DLL"-error. Seems that in winnt\system32 two older Scalix-dll´s (sclxresde.dll, sxfb32.dll) could not be updated or removed. Same dl´s with newer Versions resist in Scalix Connect programm directory. After deletion of the older Versions in system32 everything works fine.
bye,
Zoran Lorencic
