Time zone new created users have wrong time zone GMT+8

Question

New users that get created in our hybrid on premise O365 get assigned the wrong timezone. In outlook new users shows GTM+8 by default We are in UTC+01. As result all new user shows as 8 hours advanced. How can we change this, is this set it a template? if so where can I change this?

Hi @Arno Cools

Welcome to the Microsoft Q&A platform!

You can make changes to the wrong time zone user in the following ways:

1.Connect to Exchange Online using PowerShell:

$UserCredential = Get-Credential
Connect-ExchangeOnline -UserPrincipalName $UserCredential.UserName -ShowProgress $true

2.Change the user's time zone:

$users = Get-Mailbox -ResultSize unlimited -Filter{(RecipientTypeDetails -eq <RoomMailbox>)}
$users | %{Set-MailboxRegionalConfiguration $_.Identity -TimeZone <Pacific Standard Time>}

For more details on the parameters, you can refer to:https://learn.microsoft.com/en-us/exchange/troubleshoot/user-and-shared-mailboxes/incorrect-missing-time-zone-settings
