Create a function to set the tenant alias in CIPP

[jonwbstr]

You need to get the current groups to run this command and keep the existing groups I don't use tenant groups and did not look into how that could be done.

# Get tenant names from the https://api.partnercenter.microsoft.com/v1/customers MSPC endpoint. 
# This function is a workaround while until the following feature request is implemented https://github.com/KelvinTegelaar/CIPP/issues/6057
# The live company name is also available from Get-CIPPTenantDetails
$t = Get-M365Tenants
$tht = $t|group tenantid -AsHashTable

# Get CIPP Tenants
$ct = Get-CIPPTenants

# compare the live name with the name in CIPP
$ct2 = $ct|?{$tht.($_.customerid).companyname -ne $_.displayname}|select *,@{n="MSPCDisplayName";e={$tht.($_.customerid).companyname}}
$ct2 = $ct2|?{$_.mspcdisplayname}
$ct2|select customerId,displayname,mspcdisplayname

This is what I used prior to making this function:

$endpoint = "/api/EditTenant"
$method = "POST"

$ct2|%{
        $body = @{tenantAlias = $_.MSPCDisplayName; tenantGroups = @(); customerId = $_.customerId}
        Invoke-CIPPRestMethod -Endpoint $endpoint -Method $method -Body $Body
}

This is what I will use when syncing names manually in the future:

$ct2|%{
        Set-CIPPTenantProperty -CustomerTenantID $_.customerId -TenantAlias $_.MSPCDisplayName
}

Function name should be the same as the file name. You reference 3 names in total:

• Set-CIPPTenantProperty
• Set-CIPPTenantProperties
• Set-CIPPCustomVariable

I'm guessing you want it to be named Set-CIPPTenantProperty? :)
