Error when using SPO-Site to rename Site name

[tcboeira]

Hello,

Basically, I need to change the name of a website. However, the following error occurs:

Set-SPOSite -Identity https://mytenant.sharepoint.com/sites/mysite -Title 'New Title'

Set-SPOSite : https://mytenant.sharepoint.com/sites/mysite é um conjunto de sites de Grupos. Os parâmetros válidos para esse tipo de conjunto de sites são "-Identity", "-AllowSelfServiceUpgrade", "-DefaultLinkPermission", "-DefaultSharingLinkType", "-DenyAddAndCustomizePages",

"-DisableCompanyWideSharingLinks", "-DisableSharingForNonOwners", "-LockState", "-Owner", "-ResourceQuota", "-ResourceQuotaWarningLevel", "-SandboxedCodeActivationCapability", "-SharingCapability", "-ShowPeoplePickerSuggestionsForGuestUsers", "-SocialBarOnSitePagesDisabled",

"-StorageQuota", "-StorageQuotaReset" e "-StorageQuotaWarningLevel".

No linha:1 caractere:5

+     Set-SPOSite -Identity https://mytenant.sharepoint.com/sites/mysite -Title $NewTitle

+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : NotSpecified: (:) [Set-SPOSite], ServerException

    + FullyQualifiedErrorId : Microsoft.SharePoint.Client.ServerException,Microsoft.Online.SharePoint.PowerShell.SetSite

I can change the group name, if it is connected to Teams I change the name too, but the Site name always gets this error. In this case, my template would be GROUP#0

Do you know why this is and how it could be possible to get around it?

@tcboeira Try using below PnP PowerShell commands once: 

$SiteURL = "https://mytenant.sharepoint.com/sites/mysite"
  
#Connect to SharePoint site
Connect-PnPOnline -Url $SiteURL -Interactive
 
#Change site title
Set-PnPWeb -Title "New Title"

Are you (the Account you are using for your powershell command) the owner of the connected group?
