I think 1&1 domains and E packages are incompatible.
It appears we can verify a domain via a dummy MX record, this worked. However with E packages it seems you then have to set up multiple extra DNS records (TXT etc) that 1&1 do not allow.
If you cannot set up the records you cannot use your domain with Office365.
The only answer to this appears to be to move to a different domain provider. However 1&1 will not let you do this within 60 days of registering a domain. So, having paid for Office365 for a year and bought a domain through 1&1 it is not possible to use them together.
Could an admin please confirm this analysis is correct, or better still, provide a work around?
Thank you in advance, any assistance appreciated.
