You can use the Guided Search Wizard for VMWare Compatibility Matrix to figure out if a certain version of ESX or feature is supported by a certain server or hardware platform:
Technically, you can't set up out-of-office for shared mailboxes through a normal way, because you can't log in with Outlook on those accounts. A workaround would be to temporarily convert it to a regular mailbox, grant a license to it, and then log in with Outlook, but this is not always possible or desired.
Fortunately, you can also enable out-of-office through Powershell on any mailbox, including shared and resource mailboxes.
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).
