Hi,

I want to add TXT zone for MS Teams on my domain, but i’ve got this error “Another RRset with the same subdomain and type exists for this domain. (Try modifying it.)”.

I only have txt for SPF on @, how can I solve this problem ?

Thank you

Hi Lanklan,

the error message already explains it: You SPF record is part of a TXT RRSet at the apex of your zone. You can not add another TXT RRSet at the same locations. Instead, try adding a new record to the existing TXT RRSet.

Hi,

With Microsoft Teams it’s a zone with “MS=XXX”. Why do I mix it with SPF ? I don’t understand ..

Hi Lanklan,

if you’re using deSEC’s WebUI to manage your DNS records, simply find your SPF record and click “+ add another value” below. Enter the “MS=…” value you need.

If you’re using the API directly, issue a PUT or PATCH request, supplying both records in the records parameter (see docs).

If you’re using some third-party API client, check it’s documentation on how to modify existing RRSets.
