Mailbox Time/Date-Language Configurations in Exchange Server

Time, date and language configurations are made for each mail account created on the Exchange Server. This process is generally asked when performing the LOGIN operation via OWA after the first account is created.

In this article, we will configure the Date/Time and Language for the mail accounts we created on the Exchange Server using PowerShell.

Set Time Zone for a Single Mailbox in Exchange Server

To set the time zone for a specific user, you can use the following PowerShell command:

Set-MailboxRegionalConfiguration -Identity "KullanıcıAdı" -TimeZone "Istanbul"
Set-MailboxRegionalConfiguration -Identity Cengiz -TimeZone "Istanbul"

Set Time Zone and Language for a Single Mailbox in Exchange Server

To set both time zone and language for a user, you can use the following command:

Set-MailboxRegionalConfiguration -Identity "KullanıcıAdı" -TimeZone "Istanbul" –Language "tr-TR"
Set-MailboxRegionalConfiguration -Identity Cengiz -TimeZone "Istanbul" –Language "tr-TR"

Set Time Zone, Language, Date and Time Format for a Single Mailbox in Exchange Server

To set a user's time zone, language, date, and time format:

Set-MailboxRegionalConfiguration -Identity "KullanıcıAdı" -TimeZone "Istanbul" –Language "tr-TR" -DateFormat "dd/MM/yyyy" -TimeFormat "HH:mm"
Set-MailboxRegionalConfiguration -Identity Cengiz -TimeZone "Istanbul" –Language "tr-TR" -DateFormat "dd/MM/yyyy" -TimeFormat "HH:mm"

Set Time Zone for All Mailboxes in Exchange Server

To set the time zone for all user mailboxes in the organization:

$Users = Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'UserMailbox')}
$Users | ForEach {Set-MailboxRegionalConfiguration $_.Identity -TimeZone "Istanbul"}

Set Both Time Zone and Language for All Mailboxes in Exchange Server

To set both time zone and language for all user mailboxes in the organization:

$Users = Get-Mailbox -ResultSize unlimited -Filter {(RecipientTypeDetails -eq 'UserMailbox')}
$Users | ForEach {Set-MailboxRegionalConfiguration $_.Identity -TimeZone "Istanbul" –Language "tr-TR"}

Set Correct Time Zone for Mailboxes with Wrong Time Zone in Exchange Server

To set mailboxes with the wrong time zone to the correct time zone:

$Mailboxes = Get-Mailbox
ForEach ($Mailbox in $Mailboxes) {
    $RegionalConfig = Get-MailboxRegionalConfiguration –Identity $Mailbox.Identity
    if ($RegionalConfig.TimeZone -ne "Istanbul") {
        Set-MailboxRegionalConfiguration -Identity $Mailbox.Identity -TimeZone "Istanbul" -Confirm:$false
    }
}

Set Time Zone for a Single OU in Exchange Server

To set the time zone for all mailboxes in a specific Organizational Unit (OU):

Get-Mailbox -OrganizationalUnit "careexchange.in/Users" | Set-MailboxRegionalConfiguration -TimeZone "Istanbul"
