Here is the situation.
OS: SBS 2008 (EX 2007)
I have tried to find solution to this problem for several hours and I can not get BlackBerry to work with OWA/blackberry services.
I found this article that tells that there is a problem setting up OWA setup.
KB18567-BlackBerry Internet Service cannot connect to a Microsoft Outlook Web Access account using Microsoft Exchange 2007 or Microsoft Exchange 2010
so I entered the domain name and tried the link.
That did connect me to the services, but any type of authentication fails. I use usernames. usernames with domains etc.
I checked authentication settings for OWA in IIS and in Exchange and they are both correct.
When I tried totally different domain, and it authenticates without any problems.
The customer has a different email account on his blackberry like yahoo which works with his black berry (but that is most likely POP/IMAP).
I know I could instal BES free version, but I would like to use OWA.
Any help appreciated.
