Have anyone faced this issue.. outlook for mac 2011.. exchange server 2007 sp3 UR 5.... scenario
1. site A internet facing CAS... CAS proxy enabled for Site B.. mails with attachment can be send to mailboxes residing on site A mailbox Server.
2. Site B ... when mail sent with Site A CAS (cas to cas proxy) to site B mailbox .. the http error: http request cannot be fulfilled error -18500
have tried all the settings that needs to be done on ews.config file but still the CASto CAS proxy the mails larger than 1 mb gives error.
tried to send directly mail using site B cas and mails get delivered site B mailbox user. Seems there is some issue while proxying ews request from site A to site B.
