Disable the Calendar on a User or Shared Mailbox In Exchange

This works for Office365 or an internal Exchange server to disable the calendar on a Shared Mailbox or User’s Mailbox. First, you’ll have to pull up the Exchange Management Shell. Then run the following commands:

New-OwaMailboxPolicy –Name “New Policy Name”

Creates a new mailbox policy

Set-OwaMailboxPolicy –Identity “New Policy Name” –CalendarEnabled $false

Sets the calendar for all mailboxes under the policy to be off

Set-CASMailbox –Identity “shared mailbox” –OwaMailboxPolicy “newpolicy”

Applies the policy to the mailbox in question


Enabling SMB1 or CIFS on Windows Server 2012

Ran into this this week. Even though I hate doing it and definitely don’t recommend it, I had to enable CIFS on a Server 2012 instance. To do this, you first have to install the “SMB 1.0/CIFS File Sharing Support” Feature, and then do the following:

Open the Registry Editor, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer and change the value of DependOnService from SamSS Srv2 to SamSS Srv.

Reboot the server and that’s it! Enjoy your legacy application / device!

Outlook 2016 Crash at Startup

Ran into this one today… the Office 2016 Preview for Mac crashes. The solution is to open Terminal and run the following commands:

defaults delete com.microsoft.Outlook

killall cfprefsd

They delete old preference files and then kill cached preferences. Voila!

Using Dell Command Configure to Enable TPM for Bitlocker

After configuring Wake On Lan via Command Configure in a previous post, I then wanted to enable Bitlocker on the Windows 8 machine. Unfortunately, the Dell laptop did not have TPM enabled in the BIOS, which allows for a secure key to be saved. Command Configure to the rescue!

There are a few commands you have to run. For some reason, Dell requires you to have a BIOS password to enable the TPM. Don’t worry, you can enable it and disable it all at once without needing to reboot the machine. Here is what you need to run:

cctk –setuppwd=biospassword        // This sets a BIOS password

cctk –tpm=on –valsetuppwd=biospassword         // This turns TPM on and provides the BIOS password you set previously

cctk –tpmactivation=activate –valsetuppwd=biospassword          // This activates TPM and provides the BIOS password you previously set

cctk –setuppwd= –valsetuppwd=biospassword          // This removes the BIOS password. Just put one space after the = sign. You need to feed the old BIOS password to make the change.

That is it! You’ll have to restart the computer and Windows will see the TPM device and be able to enable Bitlocker.

Using Dell Command Configure to Enable Wake On Lan (WOL)

I’ve been playing with Dell Command Configure recently and will be doing a few posts on my work.

First up is enabling Wake On Lan (WOL) on Dell Optiplex, Latitude, XPS, Insprion, systems. The main advantage is this can be done remotely, through Windows, and can even be scripted.

You’ll need Dell Command | Configure which you can grab from here. If you are interested in more features, you can read up on the full documentation in the Reference Guide here.

After you install it, you can open the aptly named “Command Configure Command Prompt” tool. From there, you can enter all your arguments that you want to change. To change your Wake On Lan settings, simply type in:

cctk –wakeonlan [enable, disable, enablewakeonwlan, lanorwlan]

The options above are what you can do. You can set it to wake on just wireless, or both wireless and ethernet LAN. For both wlan and lan, your command would be:

cctk –wakeonlan lanorwlan

Fix for Slow Internet Speed While On VPN

I’ve encountered this more times then I’d like to say. Basically, when you create a VPN connection in Windows it automatically routes ALL traffic, even traffic not for the remote LAN over the VPN connection. This slows things down considerably. To stop this, do the following:

  • Go into the Properties of the VPN Connection
  • Go to the Networking Tab
  • Select TCP/IPv4 and click “Properties”
  • Hit “Advanced” and then uncheck “use default gateway on remote network”
  • Click OK until you are out of the menu system

That is it!

Generate Mailbox Size and Usage Report using PowerShell for Exchange 2010 / 2013

Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,

Exchange 2010 Add Mailbox Folder Permissions including Subfolders

I was asked by a user today for access to a specific folder in an old user’s mailbox within Outlook. There were no free computers and so the easy way out of setting up Outlook with the mailbox was not an option. I fired up Google and found this handy script for use in the Exchange Console:

ForEach($folder in (Get-MailboxFolderStatistics AliasofSharer| Where { $_.FolderPath.ToLower().StartsWith(“/Invoices“) -eq $True } ) )
$foldername = “AliasofSharer:” + $folder.FolderPath.Replace(“/”,”\”);
Add-MailboxFolderPermission $foldername -User AliasofRequestor-AccessRights PublishingEditor

  1. Change the name of the folder to be shared to where Invoices is here: ‘FolderPath.ToLower().StartsWith(“/Invoices“)’
  2. Change ‘AliasofSharer’ to the alias of the user who will be sharing the folder
  3. AliasofRequestor is who will be given access to said folder
  4. In the above example I’ve used PublishingEditor but this can be changed as required.
