Hi there

I deleted /sites/SiteA 2 days ago and checked the option to delete the associated MS Team etc. Even after 48 hours when I try to create a new Teams site with the same URL /sites/SiteA, I get this error

An error occured while trying to create the Microsoft 365 group with the alias 'PDO' : 'The group alias already exists.'.

Any thoughts on how to get past this, please?

Thank you so much.

    Hi @frob-0826 ,

    Does this error still persist now? Per my test, a few minutes after I deleted the site, I can rebuild a new site with this name. You could try to delete this M365 Group in SharePoint Admin center>Groups and try again to see if it works.

    There's a "grace" period after you delete a site/group, if you want to speed things up you need to "hard delete" them.
