Question

Is it possible to add multiple emails onto an outlook profile?

Tony 0

I am attempting to add new users emails to an existing outlook email profile without the use of Azure or Exchange. I have tried using this PowerShell script but I am unable to see the new user's email in the outlook profile.

# Prompt the user for input 
$profileName = Read-Host "Enter your existing Outlook profile name" 
$emailAddress = Read-Host "Enter the email address of the additional account" 
$password = Read-Host "Enter the password for the additional account" -AsSecureString  

# Convert the secure string password to plain text 
$passwordText= [System.Runtime.InteropServices.Marshal]::PtrToStringAuto([System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))  

# Add the new account to the existing profile 
$accountPath = "HKCU:AppData\Local\Microsoft\Outlook\Profiles\$profileName\9375CFF0413111d3B88A00104B2A6676\" $accountNumber = Get-ChildItem $accountPath | Measure-Object | Select-Object -ExpandProperty Count $accountNumber++  

# Set default server values if not provided
if ([string]::IsNullOrEmpty($smtpServer)) {     $smtpServer = "smtp.example.com" } 
if ([string]::IsNullOrEmpty($imapServer)) {     $imapServer = "imap.example.com" }  

# Create the new account registry key $accountKeyPath = Join-Path $accountPath $accountNumber New-Item -Path $accountKeyPath -Force | Out-Null  

# Set the new account properties 
Set-ItemProperty -Path $accountKeyPath -Name "SMTP Server" -Value $smtpServer 
Set-ItemProperty -Path $accountKeyPath -Name "IMAP Server" -Value $imapServer 
Set-ItemProperty -Path $accountKeyPath -Name "SMTP User" -Value $emailAddress 
Set-ItemProperty -Path $accountKeyPath -Name "SMTP Password" -Value $passwordText 
Set-ItemProperty -Path $accountKeyPath -Name "SMTP Port" -Value 587 
Set-ItemProperty -Path $accountKeyPath -Name "IMAP Port" -Value 993 

# Display a confirmation message 
Write-Host "The additional email account has been added to the '$profileName' profile."

Am I going in the right direction? Should I use another method? Thank you in advance for your assistance!

Hi @Tony ,

Welcome to our forum!

I am attempting to add new users emails to an existing outlook email profile without the use of Azure or Exchange.

What do you mean about "without the use of Azure or Exchange"?

As i know, we can only add email accounts one by one to a Outlook profile manually in Outlook desktop client. Please open Outlook and click File>Add Account.

Hello Christy,

I was attempting to add a new email account to an existing Outlook profile that is already on our domain. I was trying to use a PowerShell script in order for the user to enter the profile they wanted to add the email account to, add their new email address, and add their new password. This was supposed to be a quick automation for the end-user, but I guess the only way to do so in Outlook 2016 is to do it manually.

Hi @Tony ,

Agree with you, we need do this manually.

Are you logged in as that user? The "HKCU" (HKEY_CURRENT_USER) you're updating may be your own, not the target user!

Howdy Rich,

I feel like if I were to log into the new user's account to set it up for them, it would still give me the same results. I feel this way because the current user is prompted to enter their provided domain specific email address and password in order to create the new Outlook account. Therefore, the current user would matter? I could be wrong, but I am also wondering if I need to use an extended-MAPI? Thank you for your response Rich!

Edit: I tried logging in as another user and it still does not work :(

I'm a bit confused. The $accountPath variable, at first glance, I thought was a registry reference (HKCU). But looking closer it looks like a registry shortcut followed by a location in the file system (in the users' profile directory?).

Using MAPI to alter an existing profile is one way to do it. Another way is to modify the registry. But modifying the registry means working with GUIDs, and I've not found a ready reference to what each GUID contains (and there are many of them!). Years ago (almost 20, really) I had to do this for a mass email migration. At that time I used KixStart (it was before PowerShell came with Windows). It took a long time to suss out which GUID (key) and property did what with Outlook. Unfortunately, I no longer have the script.

Unless there's something like an Outlook profile template, probably the best way to do this is to start Outlook on a machine that has no Outlook profile and then set up the profile the way you want it. Then examine the registry and locate the keys, properties, and values you need. From that information, create your script to modify the profile created from Outlooks' first use.

Someone from the Outlook area would be better qualified to guide you in this. They might give you a VB script as a reference to work from.

Yes, the HKCU was a registry shortcut to locate the user's profile in order to add an additional email account to the profile.

I have used the Office Customization Tool, but it really doesn't do much since it is using Office 365. I am able to access the registry, but I am unable to locate the keys/properties/values needed for my script. Do you know how to can obtain them?

Thank you for your input Rich! I will be actively trying to find solutions and keep you updated.

Just to give you an idea of what one of those additional email systems looks like, I found my gmail.com account here:

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Profiles\Outlook\9375CFF0413111d3B88A00104B2A6676\00000004

A lot of the data in there is in binary and won't be the same for every user.

Note that the "16.0" in the key is the Outlook version, and there may be several depending on how many different versions of Office have been used on the machine.

Also note that "HKCU" is the user currently logged on. If you're not that user you need to get the users' SID and use that. The user may be local user or a domain user.

Here's where the profiles are on the machine:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

. . . or you can try Get-ADUser and/or GetLocalUser.

I was able to locate the correct path for the Outlook profile thanks to your comment.

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\S-1-5-21-3032970520-4117709591-2976762979-5678"

Now there is an error code of:

Set-ItemProperty : The property string SMTP Server=smtp.example.com does not exist or was not found.
At line:27 char:1
+ Set-ItemProperty -Path $accountKeyPath -Name "SMTP Server" -Value $sm ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ReadError: (string SMTP Ser...example.com:PSNoteProperty) [Set-ItemProperty], IOException
    + FullyQualifiedErrorId : SetPropertyError,Microsoft.PowerShell.Commands.SetItemPropertyCommand

I was trying to find a way to set the smtp/imap for the account, but the only results I could find were pertaining to sending emails, not setting up emails. Do you know of a way around this?

There are 20+ values that are present in the IMAP key I noted in my last post.
