Exchange 2019 new maibox or resource created with pacific time zone

Question

Every time a mailbox or resource is created the calendar is set to the pacific time zone. Is there a way to default to eastern? I know how to change it after using Exchange Shell set-mailboxcalendarconfiguration, I would like to have new mailboxes or resources created with the eastern time zone.

Answer 1

Hi @Aaron Christenson ,

When a mailbox has been created, you could run the following command.

Set-MailboxRegionalConfiguration -Identity "user@tenant .onmicrosoft.com" -Language 2057 -TimeZone "Pacific Standard Time" -LocalizeDefaultFolderName

I think you can't set the default time zone settings in the server level.

Answer 2

Hi,
You may change the default time zones of mailboxes created in a specific OU with the cmdlet
Get-Mailbox -OrganizationalUnit "domain/Users” | Set-MailboxRegionalConfiguration -Language en-GB -DateFormat "dd/mm/yyyy" -TimeFormat "hh:mm" -TimeZone "W. Europe Standard Time"

Answer 3

Hi AaronChristenson-3575,

1. I agree with the above suggestions.
   You could run the following command to modify the regional settings of a mailbox.
   Set-MailboxRegionalConfiguration -Identity <> -Language "en-US" -DateFormat "M/d/yyyy" -TimeZone <> -TimeFormat "h:mm tt"

For more information:Set-MailboxRegionalConfiguration.
2. You also could run the following command to set the Time Zone settings for specified OU.

Get-Mailbox -OrganizationalUnit "domain/Users” | Set-MailboxRegionalConfiguration -Language en-GB -DateFormat "dd/MM/yyyy" -TimeFormat "HH:mm" -TimeZone "<>"
