Modern Communication Site: Can't rename Site title

[Marcel Haas]

What happens, when you rename a communication site? 

As it's not bound to a Office 365 Group, I just rename it in the classic way under Site Settings > Title. The new title gets accepted in the settings UI and changes in the frontend until I reload the page several times. After reload I'm back to the old title. I'm seeing same issues when editing the navigation settings over the inline edit control. Changes are here for a little while and dissapear then. Changes made to navigation over site settings are more likely to be persisted.

Thx for your inputs!

Best, Marcel

Hi @martinLaplante, This is the first time i've used this platform in a while. Thanks for your response. i have to change 10K site names so i'm sticking with PowerShell to do this. I used the following code which works for the languages, i log in to settings and i can see it's swiched them off. the switch on "site is multilingual" i'm not sure if it's working tbh. I've tested this on a handful of sites, some seem stable for a day. others are jumping back. I can't make sense. perhaps i shouldn't use the $web.ismultilingual switch? We only use English at the moment. so i'm happy to just switch them all off and change title.

Ahh. I'm thinking about what you're saying. perhaps i need to only switch off the languages and not multilingual switch? I'll test this now.

[#4]

My sites are bound to 365 groups. I think i need to change them in Active Directory. Anyone have a script? thanks

[#5]

$Web.IsMultilingual is, in my opinion, not useful. I always leave it to true, Ten years ago certain web templates didn't support multiple languages, for example the classic teams blog template. It doesn't do anything, I wouldn't change it. Yes, that code should work to remove alternate languages. I see that it is using some language codes for Serbian that are no longer supported in SharePoint Online. You'll want to use 3098 and 2074 for Serbian, 10266 was changed a year or two ago, might still exist on prem.

This is unrelated to the Multilingual Page Publishing feature I was referring to, and since you are using PowerShell and not the graphical UI, there is no need to turn it on or off. It doesn't affect the site title, it just changes the interface for editing the title. If you only use English, then you probably never turned it on, no need to turn it off, removing alternate languages deactivates it anyway.

Bound to 365 groups? Groups will change the title back. Same with some Teams sites.

[#7]

Yep. that's what it must be. what can i do? Will changing the group name update the site name? Or should i do both? or do i have to do it in all environments? Exchange/Teams/AD/SP....

@Martin Laplante - For modern Team Sites you need to change the group name in Active Directory using set-azureADGroup cmdlet and it's stable. I was lost in the wrong thread. Thanks again!
