Who all has had problems with 2013 proxing requests to 2010? I tried a migration and couldn't even get OWA to proxy or redirect. I was receiving errors like this:
- Autodiscover would fail for 2010 users but fine for 2013 users:
HTTP Response Headers:
request-id: d1e90875-53e1-4be5-ad64-24a9a5eb0c19

and
Created a new user on 2010 and login to OWA does this:
Microsoft.Exchange.Data.Storage.NotSupportedWithServerVersionException
I've tried it multiple ways and I've actually done this migration before. Either way this was the same AD site, and I checked/tried the following:
- Checked AD Replication and it was fine
- Exchange 2013 was at SP1
- Exchange 2010 was at SP3 Rollup 6
- Exchange 2010 was a single server with CAS/HUB/Mailbox
- Exchange 2010 was not using a CAS Array
- Exchange 2013 had two mailbox servers in a DAG and one CAS server
- I've tried both setting all external URL's on 2010 to https://legacy.domain.com/* and also not setting External URL's. Neither fixed the issue
- https://legacy.domain.com/autodiscover/autodiscover.xml worked fine (600 invalid request response) and https://owa.domain.com/autodiscover/autodiscover.xml worked fine too (2013) but Test Connectivity and Outlook didn't work
- I checked for bad HTTP Redirections on new and old servers and made sure there were no HTTP redirections added
Would really love some input to see what I did wrong. Thank you!
