I am new to ManageEngine Plus as a Administrator, I have used it as a tech before but I cant seem to set it up properly. Have a few questions, I might be missing some steps but I prefer asking then having to mess up

I am using ManageEngine ServiceDesk Plus 8.1.0 Enterprise Edition, I have my requesters puled up from AD, all requesters can log in to the system and place requests but what I cant configure is, a MS an email account that alerts technicians and also cant configure the technicians account to log in to the ManageEngine site (with domain accounts not locally) and pick the request 

Any feedback is appreciated 

Thanks
