Avatar of Mr.XMr.X"msExchangeHideFromAddressLists" - this attribute property is missing from AD user in server Hi, got a server running DC got office365. got ADSync going on between DC and Office365 now i need to hide few users from global address list. when i try to do it in office365, it gives me an error - i know its because there is a sync going on. in AD, user attributes editor tab- i could not find "msExchangeHideFromAddressLists" - this property is missing. upon research i found, i need to extend the active directory schema to contain the required exchange attributes. if i install the evalution version of exchange 2013 in my server, will it create any problems with my office365 emails ? ? ? i found this solution from the below article. https://www.tachytelic.net/2017/11/office-365-hide-a-user-from-gal-ad-sync/
