Modifying Outlook profiles in Outlook 2010 with VBS and Powershell

Outlook profiles can present somewhat of a challenge to any mail administrator regardless of the size of the mail system. One way of looking at Outlook profiles is that they are just a whole collection of registry settings on a machine which is true but the number and compelxity of structures involved means that if you want to write a script that will modify a particular profile for a particular user its not just as simple as modifying a single registry key. In previous versions of Outlook you could generally rely on the GUID "13dbb0c8aa05101a9bb000aa002fc45a" to locate the key where the values for the Exchange settings are located but if you have done any work with Outlook 2010 on windows 7 you will generally find this is nolonger the case and its now more reliable to enumerate all the keys under a particular profile and find a particular setting which will indicate this particular key has the values for the Exchange Setting you want to modify. The one thing that computers are really good at is processing things quickly so if you wanted to for instance modify the cache mode setting within a profile in VBS you could use the following code to locate the default profile

Set WshShell = WScript.CreateObject("WScript.Shell")
strComputer = "."
HKEY_CURRENT_USER = &H80000001
Set oReg = GetObject("winmgmts:\\" & strComputer & "\root\default:StdRegProv")
keypath = "Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\"

profile = WshShell.RegRead("HKCU\"&keypath&"DefaultProfile")


Then enumerate all the keys under this profile to identify the key that has the cache mode value.

oReg.EnumKey HKEY_CURRENT_USER, (keypath & profile & "\"), arrSubKeys
For Each subkey In arrSubKeys
oReg.EnumValues HKEY_CURRENT_USER, (keypath & profile & "\" & subkey & "\"), arrSubValues
on error resume next
for each ValueKey in arrSubValues
if ValueKey = "00036601" then
oReg.GetBinaryValue HKEY_CURRENT_USER,(keypath & profile & "\" & subkey),"00036601",prProxyValRes
if not IsNull(prProxyValRes) then
if prProxyValRes(0) = "132" then
Wscript.echo "Cache Mode Enabled"
else
Wscript.echo "Cache Mode Disabled"
end if
end if
end if
next
on error goto 0
next

If you want to change the setting instead of just echoing it out the current setting then you would need to include something like

newValue1 = Array(&H84,&H05,&H00,&H00)
oReg.SetBinaryValue HKEY_CURRENT_USER,(keypath & profile & "\" & subkey),"00036601",newValue1


Note the hex value that you put in the second array element can vary depending on whether you want to enable the download public folder or shared folders check boxes.

If you think vbs is for mugs and you want to do this in powershell instead then you would need something like this

$RootKey = "Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles"
$pkProfileskey = [Microsoft.Win32.Registry]::CurrentUser.OpenSubKey($RootKey, $true)
$defProf = $pkProfileskey.GetValue("DefaultProfile")
$pkSubProfilekey = [Microsoft.Win32.Registry]::CurrentUser.OpenSubKey(($RootKey + "\\" + $defProf), $true)
foreach($Valuekey in $pkSubProfilekey.getSubKeyNames()){
$pkSubValueKey = [Microsoft.Win32.Registry]::CurrentUser.OpenSubKey(($RootKey + "\\" + $defProf + "\\" + $Valuekey ), $true)
foreach ($values in $pkSubValueKey.GetValueNames())
{
if ($values -eq "00036601"){
if(($pkSubValueKey.GetValue("00036601"))[0] -eq 132){
"Cache Mode Enabled"}
else{
"Cache Mode Disabled"
}
}
}

Export calendar Items to a CSV file using Microsoft Graph and Powershell

For the last couple of years the most constantly popular post by number of views on this blog has been  Export calendar Items to a CSV file using EWS and Powershell closely followed by the contact exports scripts. It goes to show this is just a perennial issue that exists around Mail servers, I think the first VBS script I wrote to do this type of thing was late 90's against Exchange 5.5 using cdo 1.2. Now it's 2020 and if your running Office365 you should really be using the Microsoft Graph API to do this. So what I've done is create a PowerShell Module (and I made it a one file script for those that are more comfortable with that format) that's a port of the EWS script above that is so popular. This script uses the ADAL library for Modern Authentication (which if you grab the library from the PowerShell gallery will come down with the module). Most EWS properties map one to one with the Graph and the Graph actually provides better information on recurrences then...

Downloading a shared file from Onedrive for business using Powershell

I thought I'd quickly share this script I came up with to download a file that was shared using One Drive for Business (which is SharePoint under the covers) with Powershell. The following script takes a OneDrive for business URL which would look like https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filename.txt This script is pretty simple it uses the SharePoint CSOM (Client side object Model) which it loads in the first line. It uses the URI object to separate the host and relative URL which the CSOM requires and also the SharePointOnlineCredentials object to handle the Office365 SharePoint online authentication. The following script is a function that take the OneDrive URL, Credentials for Office365 and path you want to download the file to and downloads the file. eg to run the script you would use something like ./spdownload.ps1 ' https://mydom-my.sharepoint.com/personal/gscales_domain_com/Documents/Email%20attachments/filen...

Sending a MimeMessage via the Microsoft Graph using the Graph SDK, MimeKit and MSAL

One of the new features added to the Microsoft Graph recently was the ability to create and send Mime Messages (you have been able to get Message as Mime for a while). This is useful in a number of different scenarios especially when trying to create a Message with inline Images which has historically been hard to do with both the Graph and EWS (if you don't use MIME). It also opens up using SMIME for encryption and a more easy migration path for sending using SMTP in some apps. MimeKit is a great open source library for parsing and creating MIME messages so it offers a really easy solution for tackling this issue. The current documentation on Send message via MIME lacks any real sample so I've put together a quick console app that use MSAL, MIME kit and the Graph SDK to send a Message via MIME. As the current Graph SDK also doesn't support sending via MIME either there is a workaround for this in the future my guess is this will be supported.
