Unable to switch to Teams-only mode
- Hi Robert K
Could be an issue with the TAC. Try with Powershell

Let me know how you get on. Hope this answers your question
Best, Chris

You need to make sure you donøt have any wildcard DNS records, as the Teams upgrade experience will try and do a DNS lookup for the SfB on-prem Autodiscover records.
If you can't remove the wildcard A or CNAME records, you will need to enter the Office 365 admin center and enable Skype For business services for your domain,s and get the DNS records for Skype for Business Online setup in DNS so the Teams upgrade experience can then determine that you are not using Skype for Business on-prem.
If you ask me, they should add a -Force switch to the PowerShell command 😉
Michael MardahlAre you saying to remove the lyncdiscover and sip cnames? We have been using skype online only and the DNS entries look correct for our domain but we are using a wild card and are seeing this error. I don't want to remove the DNS entries if that isn't the fix.
kevinlause You don't need to remove the Wildcard. Just make sure, that the correct SIP-records are set, from the templates in the admin-panel in 365.
I had the same issue, where we couldn't switch to 'Teams Only':
- New tenant
- No prior SfB setup, hence no SIP-records in DNS.
- Wildcard on primary domain.
I added the SIP-records and I was then able to upgrade through the TAC.
- Hey KawslabMSFT,
where can i find the Template in the 365 admin-portal?
Best regards
