It can target mailboxes by identity, by domain, from a CSV file, or all mailboxes in the organization. It also allows enabling modern protocols only or modern protocols along with EWS. Additionally, it can configure SMTP Client Authentication settings at the mailbox level. ## EXAMPLES ### EXAMPLE 1 ```powershell theme={null} Set-ExMailboxProtocol -Identity "user@example.com" -ModernProtocolsOnly ``` Sets modern protocols only for the specified mailbox. ### EXAMPLE 2 ```powershell theme={null} Set-ExMailboxProtocol -ByDomain "example.com" -GenerateCmdlets -OutputFile "C:\path\to\commands.ps1" ``` Generates the Set-EXOCasMailbox cmdlets for all mailboxes in the specified domain to enable modern protocols only and saves them to the specified file without executing them. ### EXAMPLE 3 ```powershell theme={null} Set-ExMailboxProtocol -FromCSV "C:\path\to\file.csv" ``` Sets protocol settings for mailboxes listed in the specified CSV file. ### EXAMPLE 4 ```powershell theme={null} Set-ExMailboxProtocol -AllMailboxes -ModernProtocolsAndEws ``` Sets modern protocols along with EWS for all mailboxes in the organization. ## PARAMETERS ### -ActiveSyncEnabled Set ActiveSync protocol enabled or disabled. ```yaml theme={null} Type: System.Boolean DefaultValue: False SupportsWildcards: false Aliases: [] ParameterSets: - Name: (All) Position: Named IsRequired: false ValueFromPipeline: false ValueFromPipelineByPropertyName: false ValueFromRemainingArguments: false DontShow: false AcceptedValues: [] HelpMessage: '' ``` ### -AllMailboxes If specified, all mailboxes in the organization will be processed. ```yaml theme={null} Type: System.Management.Automation.SwitchParameter DefaultValue: False SupportsWildcards: false Aliases: [] ParameterSets: - Name: AllMailboxes Position: Named IsRequired: true ValueFromPipeline: false ValueFromPipelineByPropertyName: false ValueFromRemainingArguments: false DontShow: false AcceptedValues: [] HelpMessage: '' ``` ### -ByDomain Filter mailboxes by domain name.
