BES, Exchange 2010 Hosting Mode and EWS Impersonation

I speak with a lot of people about getting BlackBerry Enterprise Server 5 working fully with Exchange Server 2010 Hosting Mode, and repeatedly come across the same problem with calendars.

While Microsoft have done an excellent job documenting Exchange Management Shell Cmdlets, RIM seems to have completely missed required sections from the deployment documentation.

With Exchange Server 2010 SP1 BES must use EWS to access calendar, to configure the service account we need to create a new Management Role.

New-ManagementScope -PartnerDelegatedTenantRestrictionFilter {Name -eq '*'} -Name BESTenants

New-ManagementRole -Parent PartnerDelegatedTenantManagement -Name BESEWS

New-ManagementRoleAssignment -Role BESEWS -User "BESAdmin” -CustomConfigWriteScope BESTenants

One thing I have been surprised by is few of the automation and control panel vendors are properly documenting this which to me suggests they may be missing steps in validating their solution.

What is your experience with Exchange 2010 /Hosting and BES?

Send as permissions with Hosted Exchange 2010

If you need to assign Send As rights with Hosted Exchange 2010 it can easily be achieved with PowerShell.
I want the user Daniel to be able to send email out as the Event DL address:

Add-RecipientPermission "Event" -AccessRights SendAs -Trustee "Daniel"

Nice and easy.


snom UC600 Optimized for Microsoft ® Lync

Well this came as surprise to me, snom have released the UC600 an Optimized for Microsoft ® Lync USB device.

To use the phone you will need Office Communicator 2007 R2 or later. I’m hopeful to get my hands on one of these to check the build quality meets the high standard on devices such as the snom 821.
