Hi, we have approximately 1000 users with Exchange mailboxes, and utilise ActiveSync with the name activesync.company.com for most users, and this works well.
However, for around 45 users (mostly senior execs, road warriors and early adopters), when we were on Exchange 2007, we used ISA 2006 server, and these people utilise an ActiveSync name of OMA.company.com that is published through ISA server, which connects to one of our Exchange CAS servers directly (no Load Balancer).
We want to decomission our ISA 2006 server, and migrate these 45 users over to using activesync.company.com - we would like to do this without having to visit these users. Is there a way to reconfigure the Android and iOS users to use the new ActiveSync load-balanced name and IP?
We don't use OWA, but our "LegacyURL" is currently blank.
We have considered DNS changes so that OMA.company.com is directed to ActiveSync.company.com - but the certificate at ActiveSync.company.com does not include any SAN names or CN for OMA.company.com
Does anyone have any guidance on how we can remotely transition these users?
