Hello I have sbs2008 and trying launch Exchange 2007. When I ran ExBPA a receive na error: 'Authenticated Users' does not have 'Read' permission of folder 'C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB\22726331-8a8b-4a7f-a74a...' on server SRV01.xxx.local. This will cause clients fail to download Offline Address Book via HTTP(s). Please add 'Read' permission of this folder to this group. the same for 'Authenticated Users, Domain Admins, Enterprise Admins', but the permission on this folder is definitly granted, even for tests I granted to everyone Full Control but it didnt help. Can someone help me with this problem?

What language is your SBS? Eg. in Polish version of Windows, domain groups are created with Polish names. That's why EXBPA make false errors (in fact proper groups have access to recources, but ExBPA check only english names of the groups) Regards, Konrad Sagala, MCT, MCSE+M, MCITP: Exchange 2007/2010
