Shutdown the VM.
Open .vmx file with Notepad or another plain text editor.
Add these lines:
hypervisor.cpuid.v0 = "FALSE" mce.enable = "TRUE" vhv.enable = "TRUE" vpmc.enable = "TRUE"
Save and start the VM. Now you can install the Hyper-V role.
Wanted to install the latest BES Express (at the time of writing, this was 5.0.4) on a fresh Windows-server. Starting Setup.exe briefly shows the Blackberry splash-screen, then immediately crashes ("this program has stopped working...").
Apparently, RIM did some sloppy programming: changing the regional settings to English (US) or English (UK) resolves the issue.
A useful Technet article on sizing Exchange 2013:
If for some reason you need to enable Basic Authentication, you can do so quickly through the Exchange Management Shell. This is sometimes needed if you're migrating to Exchange from another (third-party) e-mail provider.
If you do not know what Basic Authentication is, you do not need this!
Start up EMS as an account which has the required permissions to make changes to the virtual directories used by Exchange. Then, run this:
Set-WebServicesVirtualDirectory -Identity "EWS (Default Web Site)" -BasicAuthentication $true
Note that Office365 has Basic Authentication enabled by default.
Exchange stores plenty of things in Active Directory, including mailbox information for each account. In case of a deinstallation of Exchange, this information usually remains behind, making it impossible to perform a new clean installation of Exchange and assigning a new mailbox to this user.
This command-line tool allows you to query and/or remove Exchange-attributes on AD objects (such as users and groups).
A reminder to myself...
Set a bit:
Var |= Bit;
Clear a bit:
Var &= ~Bit;
A very interesting read about Wi-Fi implementations and its pitfalls in larger deployments, in particular about the usage of channels and the importance of channel plans.
