I am currently in coexistence mode with Exchange 2010 and Exchange 2013. When sending email from Outlook mail is delayed in Outbox for up to 20 seconds when using RPC/HTTP (Outlook 2010/mailbox on Exchange 2013). RPC/TCP works right away (Outlook
2010/mailbox on Exchange 2010). I do not see any performance issues on Exchange 2013 server. In addition 2013 OWA works right away, not sure why the delay (sometimes it goes out right away). I see the delay with mailboxes on Exchange 2010/2013/outside
of organization, but again only when connecting over Outlook Anywhere to Exchange 2013.
