Effects of "disable Exchange Fast Access" on mailboxes with disabled caching

Hi guys,

Do you know whether "disable Exchange Fast Access" affects mailboxes with disabled caching? I have users for whom caching was enabled (for their primary mailboxes), but they also have additional mailboxes for which caching is disabled.

Also, do you know whether "disable Exchange Fast Access" affects non-email content, for which caching is disabled in users' primary mailboxes?

Thanks

Zoran
