Hi,

recently we are having a problem in exchange 2010, we have several sites, each site has exchange full roles (cas/mbx/hub). We enabled outlook anywhere in one siteA (internet facing) while others not OA enabled nor internet facing. I'd like to answer, if enabling just one such CAS will enable our whole organization to use OA normally?

As afar, users in site A can use oa for outlook with fine, but other sites seems keeping prompting credential windows repeatedly?

Please kindly advise. Appreciated.

    Be sure the external URLs for the non-internet facing sites are blank:

    If you only have one site Internet facing, then do not configure any external URLs on the other servers. If you do, then all Exchange will do is redirect the user to the other sites. For proxy to work, the external URL must not be populated.
