Global Outlook Signature - Office 365 Inside

Global Signature

A global signature is like a regular signature however it’s managed by your company. This is not a disclaimer that gets appended towards the end of every email. I have gotten a lot of requests to have a global signature so here goes.

This signature will pull attributes from the user profile (MsolService | Office 365) and apply it on the Mailbox (Exchange Admin Center). So let’s first connect to the EAC (Exchange Admin Center) and Office 365 via PowerShell.

Run the Windows Azure Active Directory Module for Windows PowerShell as Admin
Run your initializing commands and enter the credentials for the Global Admin

$LiveCred = Get-Credential

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $LiveCred -Authentication Basic -AllowRedirection

Net start winrm

set-executionpolicy unrestricted -force

Import-PSSession $Session

Connect-MsolService

As always I would first do this for one user and then for the entire tenant
I will use my test user test123@spodawgs.gq and have his signature pull details from his details.
I’ll add some of his details to the signature. You can add more if you like and pretty it up
First let’s check via PowerShell if the Msol user Attributes display

Get-MsolUser -UserPrincipalName test123@spodawgs.gq | Select City,DisplayName,Office,PhoneNumber,StreetAddress,State

As you can see in the screenshot below they do.

I the run the following commands (all at once)
I have highlighted the user name and the URL for the image logo so you can change it.

foreach($user in (Get-MsolUser -userprincipalname test123@spodawgs.gq)){

$DisplayName=$user.DisplayName;

$Title=$user.Title;

$Street=$user.StreetAddress;

$Office=$user.Office;

$PhoneNumber=$user.PhoneNumber;

$MobilePhone=$user.MobilePhone;

$Fax=$user.Fax;

$Email=$user.UserPrincipalName;

$pic= “<div>$displayname

Title: $Title

Office: $Office

Phone: $PhoneNumber

Mobile: $MobilePhone

Fax: $Fax

Email:<a href=mailto:$Email>$Email</a>

<img src=’http://www.microsoft.com/favicon.ico?v2′ height=’25’ width=’25’></div>”

Set-MailboxMessageConfiguration -Identity $user.UserPrincipalName -AutoAddSignature $True -Signaturehtml $pic -defaultfontflag ALL -defaultformat HTML}

I have successfully set a signature for the user account test123
Now let’s do this for the tenant
To get the list of licensed users I ran the following command

Get-MsolUser | Where-Object { $_.isLicensed -eq “TRUE” }

Change the properties accordingly to fit your needs
I first ran the following command to set $x to licensed users with UPNs. Of course you can’t add a signature if there is no mailbox:

$x=Get-MsolUser | Where-Object { $_.isLicensed -eq “TRUE” } | Select-Object -property “UserPrincipalName”, “DisplayName”, “Title”, “Office”, “PhoneNumber”, “MobilePhone”, “Fax”

After that I ran the command listed below to set a signature for all licensed users with mailboxes.

ForEach($user in ($x))
