Chee Wai Koh 1 Reputation point


I am setting-up AAD Connect between On-Prem and Azure AD
Do I need to open inbound ports (443 and 80) from O365 IPs' to On-premise Azure AD connect server? I'm using Password Hash Synchronization method.

    Hi @Chee Wai Koh , a list of all firewall requirements can be found here. From what I can see is yes, you do need to open 443 and 80. Please let me know if you have any questions!

    If this answer helped you please mark it as "Verified" so other users may reference it.

    Thank you,

    Hi @James Hamil

    Thanks for reply, if I never turn-on password write-back feature, do I need to open inbound ports to my corporate network?
