Since Exchange 2010 SP1, when giving users Full access to another mailbox, they automatically get that mailbox added to their Outlook (2007 and up). This feature is called mailbox auto-mapping, and has made life a little easier for us IT administrators. But sometimes, you do not want a mailbox to be auto-mapped in Outlook for a particular user.

This can be achieved by setting the access permission through Powershell, and including the parameter -AutoMapping:$false in the cmdlet.

Add-MailboxPermission "Shared Mailbox" -User <user> -AccessRights FullAccess -AutoMapping:$false

You can easily view message tracking logs through the Exchange Management Shell (EMS). The cmdlet to use is called Get-MessageTrackingLog, and roughly provides the same search queries as before, and to be honest, it's faster than using the GUI in older Exchange versions, once you get to know the syntax. And thanks to the power of Powershell, you have a lot more options about exporting said data (e.g. to CSV).

The basic syntax is as follows:

Get-MessageTrackingLog [-Server <ServerIdentity.] [-ResultSize <Integer> | Unlimited] [-Start <DateTime>] [-End <DateTime>] [-EventId <EventId>] [-InternalMessageId <InternalMessageId>] [-MessageId <MessageId>] [-M  ...

You can easily reset the root password on linux-based VMWare appliances through the boot loader. For this to work, you need access to the console of the appliance (i.e. through vSphere (Web) Client), and needs to be performed during offline hours as the appliance has to be rebooted.

Reboot the appliance, and as soon as you see the GRUB boot loader, halt the automatic boot timer by hitting any key (I usually move the selection using the arrows).

Select the first entry, and press e, allowing you to type in some text. At the end of the line that starts with kernel, add the following text:


Do not remove any other text. Then press Enter to confirm.

Press b to continue the boot  ...

By default, when opening up OWA (Outlook Web App) access to the internet, you could technically also get into Exchange Admin Center (EAC) by appending /ecp after the external OWA URL, potentionally creating a security vulnerability and increasing the chance for a brute-force attack to succeed.

While it is generally a good idea to deny access to the Administrator user to manage the Exchange-server, this is not always possible or desireable. Additionally, because EAC is a VirtualDirectory within a site in IIS, it is not possible to have it listen on a separate internal IP address and secure it through the edge firewall. Luckily, IIS also has some other mechanisms to secure access. There's an   ...

You can easily find quarantined mailboxes through Powershell:

Get-Mailbox | Get-MailboxStatistics | Where { $_.IsQuarantined -eq $True } | Select Name,Alias

By default, when a user first logs on to Outlook Web App, they are prompted to choose their language and time zone. Sometimes, it's required to change these settings for a certain user, or even, for all users. This can be done by an administrative user through Exchange Management Shell (EMS), and works for both Exchange 2010/2013 and Office365, with the cmdlet Set-MailboxRegionalConfiguration.

First, open EMS for your on-premise Exchange, or for Office365, connect to Exchange Online using Powershell.

You can then set/change the language and time zone for a user like so:

Set-MailboxRegionalConfiguration -Identity -Language -TimeZone

identity speaks for itself: it can be an alia  ...

By default, in Exchange 2013, OWA prompts the user to type in their username including the logon name. This can be altered so OWA accepts usernames in a different format.

Log on to EMS and run the following Powershell cmdlet:

Set-OwaVirtualDirectory "owa (Default Web Site)" -LogonFormat Username -DefaultDomain your-domain-name

Change your-domain-name to your domain name.

Next, restart IIS to apply the changes:

iisreset /noforce

Note: not entirely correct as, in fact, you change it to the UserPrincipalName, which is not necessarily the same as the e-mail address.

Log on to EMS and run the following Powershell cmdlet:

Set-OwaVirtualDirectory "owa (Default Web Site)" -LogonFormat Pr  ...

If OneDrive for Business stays stuck at "We're getting things ready to sync..." when syncing a new library, or re-syncing an existing one, try resetting OneDrive for Business.

by lunarg on February 13th 2015, at 11:02
If for some reason (e.g. when synchronization no longer works properly), you can completely clear and reset OneDrive for Business in a few easy steps.

First, close down all Office programs (such as Word, Excel, Outlook, etc.). Next, open Windows Task Manager, look for and kill these processes:




I've noticed that sometimes, these processes get restarted automatically, so be sure they are gone before performing the next step.

Next, locate and delete these folders and their contents:



If needed, also delete the local copy of all synced libraries. The location depends   ...

Since Windows 8 introduced "fast startup", Windows no longer finishes the installation of updates when performing a regular shutdown. The next time you turn on your computer, it will ask again to restart your computer to finish the installation of updates. The reason for this is "fast startup", which does not do a full shutdown, whereas a restart does a full shutdown and startup of your computer.

You could turn off "fast startup" but who would want that, right? Luckily, there is a workaround.

When you hold down Shift, then click on the Shutdown button, your computer will do a full shutdown just this once, enabling Windows Update to finish the installation of u  ...

UPDATE: this article is no longer required as 4G for the carrier Proximus and Base are now supported by your iPhone natively!




In Belgium, the carrier Proximus is rolling out the new 4G (a.k.a. LTE) network. Proximus will be using the 1800MHz channels, which is supported by iPhone 5 and a number of Android phones (notably the Galaxy S3 and Note II). Unfortunately, Apple's policy is that carriers providing 4G first have to pass a "quality test" before they are added to the list of "supported 4G networks". Because in Belgium, Apple has a exclusivity contract with Mobistar and the latter aren't rolling out 4G just yet, results in Proximus  ...

Google Chrome v39 introduces a new Avatar menu, which is now permanently displayed at the top-right corner of each window.

The only way to get rid of it is through the "experimental" flags. Type the following in the address bar to reveal the flag:


Set it to Disabled to turn it off, then restart Chrome entirely to apply the changes.

Note that this also works under Mac and linux.

You may get an error during the upgrade of Veeam Backup & Recovery to version 8, stating that the vPower NFS service is unable to start. Alternatively, when updating the individual components, you may also get a similar error (such as: "Error 1920.Service Veeam vPower NFS Service (VeeamNFSSvc) failed to start. Verify that you have sufficient privileges to start system services.").

There are several reasons possible for this, but the most likely one is a wrong NFS Datastore path specified in the registry, usually because the drive that the datastore is pointing to, is no longer present.
Another reason could be that your server has the "NFS sharing" feature installed,   ...

Open an EMS (Exchange Management Shell), and type these in, one by one:

Get-GlobalAddressList | update-GlobalAdressList
Get-AddressList | update-AddressList
Get-OfflineAddressBook | Update-OfflineAddressBook

Some users report having to restart the Exchange File Distribution service after running these PS cmdlets.
