Hi All,
I need your help
I'm migrating exchange 2013 to exchange online. but when I created a new custom address list on exchange online but It did show members inside.
Because I created the address list after user syncing to exchange online, so I understand that I need to resync all object in AD to O365 again to update members into the address
list.
But After updating object info ( in my case, I use externalcustomattribute1 for updating each object) and resync, the address list is still empty.
I also check that the filter is working or not by using cmdlets and It shows all members in Powershell but not on UI.
