acronis 12.5 advanced Exchange log doesnt clean up or can not stop the scheduler

Hello
after using acronis for over a half year am still not to happy with it.
I used for another organisation Vmprotect 9 and this works fantastic.
for my own organisation i use Ab 12.5 but i have still a lot of issues.
My biggest issues at this moment is that the backup does clean up my log files.
i have to manual backup my exchange every month with windows backup to clean up the logs.
i also cant pause the scheduler. want to pause it for my windows backup but i wil lget this error
POR: Property 'MsSqlOptions' cannot be found.
