In a hybrid Exchange environment, you may get an error when attempting to log in to Office 365 when performing a management task involving Office 365. When clicking the "Sign in to Office 365" link, the following error is displayed:

Not really a solution, but you can work around the issue by performing these steps:

In EAC, navigate to Hybrid.

Click Modify.

Click Sign in to Office 365, type in your Office 365 username and password.

If you have the Exchange Management Tools installed, you can easily import the Exchange module into a standard Powershell by running the Add-PSSnapin cmdlet.

Depending on the Exchange version, the module to add is slightly different:

Exchange 2007Microsoft.Exchange.Management.PowerShell.Admin
Exchange 2010Microsoft.Exchange.Management.PowerShell.E2010
Exchange 2013Microsoft.Exchange.Management.PowerShell.SnapIn

If you're not sure about the version, you can also use wildcard characters:

Add-PSSnapin *Exchange*

If you don't want to install the management tools, you can also use PS remoting to remotely access the management shell from a standard Powershell.

One of the most pertinent changes to Windows 10 is how updates are being installed. Unless your computer is using WSUS or some other corporate solution, you do not have the ability to select which updates to install and which not to install. This includes drivers and feature updates (such as the Anniversary Update). While it is usually recommended to install all updates, sometimes it is not wanted, e.g. because of system instability, or simply, because you don't want a particular update (e.g. Anniversary Update). To meet customer's demand, Microsoft has released a tool to reintroduce the "hide an update" function of older Windows versions.

The tool allows you to "hide" s  ...

With PowerCLI, you can generate all sorts of lists. To retrieve the configured and reported OS version of your VMs, try running this one-liner:

Get-VM | Sort | 
   Get-View -Property @("Name", "Config.GuestFullName", "Guest.GuestFullName", "Guest.IpAddress") | 
   Select -Property Name, 
       @{N="Configured OS";E={$_.Config.GuestFullName}},
       @{N="Running OS";E={$_.Guest.GuestFullName}},
       @{N="IP Address";E={@($_.Guest.IpAddress)}} | 
   Export-CSV -Delimiter ";" -Path "vms.csv"

ADMT stands for Active Directory Migration Tool and is used to migrate AD objects (such as users, groups, computers, etc.) from one AD forest or domain to another, supporting complex scenarios in the process.

Why Microsoft hides their most useful tools is a mystery though. So here are the download links. You will need to accept some EULAs and have a Microsoft Account if you wish to download it though.

Navigate to https://connect.microsoft.com/site1164/program8540.

If you have not done so, you will have to log on with a Microsoft Account and join the program and accept its EULA things.

Then, you will be able to click through to the download page and download ADMT version 3.2, and, if req  ...

If your ESX host has lost connection to the vCenter server, but you can still directly access the host's management, and can find nothing else wrong with the vCenter server or its network connection to the host, you may want to the free space on your ESX host.

Logs and other temporary files may have filled up one or more ramdisk partitions (e.g. when you don't have a persistent scratch partition, it gets mounted on /tmp). This can cause any of the following issues:

Connection loss between the ESX host and vCenter server;

Errors when attempting to reconnect or add an ESX host to a vCenter server;

Errors while attempting to activate or configure HA;

Other unexplainable errors...

You can   ...

If the scratch partition (/tmp) gets filled up, check for the presence of the file ql_ima.log. If it is present, you are bothered by a bug from an older version of the qla4xxx driver. Even if you use Update Manager, this driver does not get updated automatically. The solution is add the driver to Update Manager or download and install the update manually.

This procedure describes the manual installation of the update on your ESX host. There's no need to put the host in maintenance mode but you will have to reboot to use the new driver.

Download the driver (you need a VMware account):

VMware 5.5

VMware 6.0

Unpack the download and copy the file qla4xxx-634.55.28.0-offline_bundle-1682448.z  ...

A new Powershell module, called Azure AD v2 is available to manage Office365 from Powershell, and is now the preferred method for managing Office365 tenants from Powershell. Unlike the older MSOnline module, you need to download and install this version from the Powershell Gallery, for which there is no direct download link.

Windows 10 already has the PowershellGet module needed to download modules from Powershell Gallery, so all you need to do is run the following in an elevated Powershell:

Install-Module AzureAD

You may get a message about NuGet provider is required to continue. You can safely confirm this.

Everything pre-Windows 10 and starting from Windows 7 SP1 and 2008R2 SP1, you n  ...
