Here is a quick powershell one liner that I came up with when I got a request from Microsoft Support to disable user protocols. I did some research and found out that they meant the protocols or services used to access Office 365 Exchange Online.

Connect to Microsoft Office365 via Powershell

Open Windows Azure Active Directory Module for Windows Powershell as Domain Administrator and type in the following to connect to Exchange Online via Powershell:

Set-ExecutionPolicy RemoteSigned
$creds = Get-Credential
(Enter the Office 365 Administrator credentials then click “OK” button.)
Import-Module MsOnline
Connect-MsolService -Credential $creds
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://ps.outlook.com/powershell/ -Credential $creds -Authentication Basic -AllowRedirection
Import-PSSession $Session

Disable User Protocols

Once connected to Office 365 via Powershell, here is the one liner to disable user protocols:

Set-CASMailbox user@company.com -ImapEnabled $False -PopEnabled $False -OWAEnabled $False -ActiveSyncEnabled $False -MAPIEnabled $False

Enable User Protocols

Here is the one liner to enable user protocols:

Set-CASMailbox user@company.com -ImapEnabled $True -PopEnabled $True -OWAEnabled $True -ActiveSyncEnabled $True -MAPIEnabled $True
