Recommendations

Exchange On-Premises: We recommend to install GALsync on a member server within the domain (e.g., dedicated GALsync server or file server). The machine should be uncritical (e.g., may be restarted without complications). The GALsync server must have a high bandwidth connection to the DC/GC. 

Exchange Online: See recommendations for on-premises; but you can use also a standalone computer.
