Hi, I have configured Exchange 2010 SP1 with Two Mailbox Servers (DAG) and Two HUB&CAS Servers (CAS Array configured).Also i have installed one TMG and Outlook WEb Access published through this and OWA is working perfectly through this. We have BlackBerry Internet service users those who are accessing from outside to access their mails. But BlackBerry users are not able connect to the exchange server. Can any one help me to configure TMG for accessing exchange 2010 SP1 using BlackBerry (BIS). Thanks Murali

Hi Murali, What is the error message users are getting? I worked on one issue recently, check out the link: http://exchangeranger.blogspot.com/2011/03/blackberry-bis-not-working-after.html Post the update.Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com
