Hello Experts. We have exchange 2013 on prem with 1 AD, 1 domain, and 1 exchange. We have more then 3000 users. Looking into migrating to O365. I have heard that password hash syncronization is not recommended for larger organizations, intead they should use pass through sync with AAD connect or ADFS. I was not able to find any reason on the internet as to why that is. Does anybody know. Please let me know. And thanks in advance.
