We have office 365 tenant with SharePoint subscription.
We also own one domain , say DOMAINNAME.COM
One of the site collection URL is :
Now, what we want is,
DOMAINNAME.COM should open the sharepoint online site collection. How this can be achieved. I have access to tenant administration but we don't have alternate access mapping like in sharepoint on-premise.
Only workaround currently we have is, putting script on domainname.com home page and redirect to sharepoint site collection. But client is not fine with this solution.
Any solution please?
