Hello,
I'm in process of migration users from Exchange 2010 to 2013 and there is some issue i faced regarding ECP redirection.
Internally all works good, but as soon Exchange 2013 is doing proxyng part (internally or externally) there is issue with non-working links and information that are not shown, as you can see in attached picture below.
my environment have:
2 Exchange 2013 CU 2 (2008 R2) CAS/MBX servers facing Internet with hostname mail.mydomain.com
2 Exchange 2010 SP3 CAS servers (NLB but i guess it is not relevant for this situation) external hostname same as in 2013 servers
2 Exchange 2010 SP3 Mailbox servers (in DAG replication, also irrelevant per my opinion)
Checked application logs on every server - no luck.
If user is on Exchange 2013, all works good.
Tried with recreating ECP directories on both sides- no luck either.
Attached is image how situation actually looks. you click on any link- nothing happens.
Any information or help is highly valuable.
Thanks!!
Ivica C.
