Send as SMTP alias ora disponibile in Exchange Online

Una delle richieste degli utenti più longeve è finalmente una realtà. Gli utenti possono finalmente inviare e-mail "come" uno dei propri indirizzi SMTP alias.

Gli amministratori di Exchange possono assegnare indirizzi email alternativi, o alias, alle cassette postali degli utenti. Gli utenti possono ricevere e-mail per uno qualsiasi dei loro alias, ma fino ad ora, e-mail e risposte possono essere inviate solo utilizzando il loro indirizzo e-mail SMTP principale. Con il nuovo comportamento, i messaggi di posta elettronica inviati utilizzando un alias, mostrano l'indirizzo del mittente e l'indirizzo di risposta come indirizzo SMTP dell'alias utilizzato.

E' possibile abilitate la funzionalità tramite il seguente cmdlet

Set-OrganizationConfig -SendFromAliasEnabled $true

Una volta impostato, gli utenti potranno inviare e-mail utilizzando uno dei loro indirizzi alias configurati, in Outlook o OWA. In Outlook, l'utente deve prima mostrare il campo Da per i nuovi messaggi di posta elettronica utilizzando il menu Opzioni, quindi scegliere un indirizzo alias o fare clic su Altro indirizzo email e digitare quello che si desidera utilizzare.

Poweroff Linux based NAS (Synology, ecc) remotely from Windows by command line

#Note - Updated 14/04/2021 
I had to turn off the NAS automatically after a Veeam backup copy process, but... it's not as simple as I thought.
The problem is that Linux SSH security permit executing of the "power off" command only as root and then root can not login to SSH

how do to do?

#Product affected / related 
NAS Linux based, Linux and Windows Server and Clients

1. Login to your NAS as admin user by SSH (PuTTY)

To enable ssh on Synology:
Control Panel > Terminal & SNMP > Terminal allows your Synology NAS to support Telnet and SSH command-line interface services. You can also change the security level of the SSH encryption algorithm.
To enable Telnet/SSH service:
Check the box next to the SSH protocol
Click Apply

2. Take permission as root
sudo su - or sudo -i

3.  Edit /etc/sudoers
vi /etc/sudoers

4: Add the following line 
## Admin user group is allowed to execute halt and reboot 
userOrGroup ALL=NOPASSWD: /sbin/halt, /sbin/reboot, /sbin/poweroff

6. Download plink (Now as part of putty)

On Windows, you have to download plink from PuTTY download page and save it in a folder.
This is the command that resolve the problem:

plink.exe -ssh -t -pw “yourpassword” admin@xxx.xxx.xxx.xxx "sudo poweroff"

Microsoft 365: How to force Modern authentication

Outlook App

In the newer versions of Outlook App, Modern Authentication is enabled by default.

In case of problems, that is the window in Outlook that continues to ask for the password, it is also recommended to force the use of Modern Authentication in Outlook, adding, through Regedit, the following registry key, setting the DWORD value to 1 


AlwaysUseMSOAuthForAutoDiscover – DWORD=1


Check to see if Modern Authentication is ENABLED for your Office 365 tenant

Run the command Get-OrganizationConfig | Format-Table Name,OAuth* -Auto

If you see “False” listed next to your Office 365 tenant proceed to the next step to enable Modern Auth. If you see “True” then Modern Auth is already enabled; no further action is required. Skip to Disconnect your PowerShell session. 

Enable Modern Authentication for your Office 365 tenant

Run the command Set-OrganizationConfig -OAuth2ClientProfileEnabled $true

Note: This command does not prevent connections via Basic Authentication. Desktop and mobile e-mail client applications which do not support Modern Authentication will still be able to connect to the Office 365 account using Basic Authentication until October 13, 2020.

Verify Modern Authentication is ENABLED for your Office 365 tenant

Run the command Get-OrganizationConfig | Format-Table Name,OAuth* -Auto

You should now see “True” listed next to your Office 365 tenant indicating that Modern Authentication is enabled for your Office 365 tenant
