Hello,
I've installed Exchange 2013 into Exchange 2010 infrastructure
[ single Exchange 2010 server; single AD site; AD = 2003 ],
and moved one mailbox [ Test user ] to Exchange 2013.
When I login internally through 2013 OWA to access mailboxes on 2010, then proxy works fine.
When I login internally through 2010 OWA to access mailboxes on 2013, then a message appears:
Use the following link to open this mailbox with the best performance: with link to 2013 OWA...
What is wrong ?
I've checked and changed settings by:
Get-OwaVirtualDirectory, Set-OwaVirtualDirectory
