External Blackberry Enterprise Server and Our internal Exchange Server.

Basically when setting up the BES (which is at blackberry) it needs to see our internal exchange server, what do i need to do to make this happen? just forward some ports? which ones?

Hope you can help,

Cheers,

Rich

If you have a BES inhouse, open port 3101.

Is your OWA already accessible externally?  If so, you should be set.  Outlook Mobile features are enabled by default in Active Directory, unless you went back and disabled them for persons.

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

When configuring the BIS Account, give it the Web URL of your OWA -
     https://owa.domain.com/exchange
Then supply the username, password, and e-mail address of the mailbox.  For the "Mailbox name" use the Exchange Alias.

If you are using POP3 connectivity, then you need to forward port 110 and 995 to the Exchange server.
If you are using IMAP connectivity, then you need to forward port 143 and 993 to the Exchange Server.

Hi, as mentioned above all you need is OWA enabled for the user and it to be accessible via the web.  Once this is confirmed the users just need to create a new account via the BlackBerry Web Client (each carrier has a different page) and add the work email address.  When you add the work address it will fail > Select to manually enter the details > Select the work email option > Select the OWA option > Enter the OWA details.

Just as a heads up the default polling interval for the Blackberry Server to check for new email is 900 seconds with a timeout of 120 seconds.  So if you users mention a 15 minute delay in receiving emails this is normal.

Thanks for all the replys, ok OWA is viewable from external sources but only if i add the security certificate exeption...understandably blackberry if having a hard time with it and still saying it cant find the server.

https://mail.*******uk.com/exchange ---this is how i can get to it externally.

BUT

The certificate is not trusted because it is self signed.
The certificate is only valid for webmail.*********bs.com.

Any Ideas on how to change the certificate? and is this why blackberry still wont work?

Cheers Guys really appreciate this.

The BIS servers will accept untrusted certificates so that is not an issue.  In active directory for that user ensure you have an internal email address listed on the Email Address tab (e.g. gary@yourcompany.local) if applicable.
