$cert = Get-ChildItem -Path Cert:\LocalMachine\My\ | where { $_.Thumbprint -eq "thumbprint" }
Set-VpnAuthProtocol -CertificateAdvertised $cert
Restart-Service RemoteAccess

In Microsoft 365 / Exchange Online, to connect a soft deleted mailbox, you have need to use the cmdlet New-MailboxRestoreRequest to restore the mailbox to another user.
Get-Mailbox -SoftDeletedMailbox | select guid
Get-Mailbox <NewMailbox> | select guid
New-MailboxRestoreRequest -SourceMailbox <GUID> -TargetMailbox <GUID of new mailbox> -AllowLegacyDNMismatch
To check the status of the restore:
Get-MailboxRestoreRequest | Get-MailboxRestoreStatistics

If you need make a room mailbox public, for example for a public event, these few PowerShell commands will help you:
First, connect to Exchange Online with your tenant admin:
Connect-ExchangeOnline
Make the calendar public and make the calendar entries visible to everyone:
Set-MailboxCalendarFolder publicRoomMailbox:\Calendar -PublishEnabled $true
Set-MailboxCalendarFolder publicRoomMailbox:\Calendar -Detaillevel Full
Show the HTML and iCalendar URL:
Get-MailboxCalendarFolder publicRoomMailbox:\Calendar | fl published*
The URLs can be shared with anyone or the HTML URL could be embedded on a website as part of an iFrame.
If you need to change a synced AD account with an Exchange Online mailbox into a cloud-only user, these are the steps you need to take:
Move the user to an OU that is not synced by AD Connect and run a delta sync on the AD Connect server (or wait for 30 minutes):
Start-ADSyncSyncCycle -PolicyType Delta
The mailbox is now in the "Soft deleted" state, which means that it is deleted but can be restored within 30 days. To view the soft deleted mailbox run this command:
Connect-ExchangeOnline
Get-Mailbox -SoftDeletedMailbox user@ajni.it | fl guid
Now link the deleted mailbox with the cloud-only user. The cloud-only user has already been created in my case. You will need to insert the user's password in order to proceed.
New-Mailbox -InactiveMailbox 7fb16ffd-cf3a-42ef-a9d3-e0293f5ef6c2 -Alias cloudOnlyUser -MicrosoftOnlineServicesID cloudOnlyUser@ajni.onmicrosoft.com
Afterwards you can either assign a license to the user or convert that mailbox into a shared mailbox which does not need a license.
Normally, with an Office 365 mailbox, you can only send mails with the primary email address. Sending from aliases was not allowed. Microsoft recently rolled out this feature which can be enabled through Exchange Online PowerShell:
Connect-ExchangeOnline
To view the current settings:
Get-OrganizationConfig | fl SendFromAlias*
To enable the feature:
Set-OrganizationConfig -SendFromAliasEnabled $true
To view the settings again:
Get-OrganizationConfig | fl SendFromAlias*
