Further to my Easyspace post regarding TXT Updates , I tried to update TXT records for domain authentication for Office 365 on a new domain , however again, there was no where in plusnet’s manage DNS control panel to do this. A call on their support number, produced the fact they do not support TXT DNS Record updates.
Luckily in 365 there is another way to verify domain ownership which is to use a low priority dummy MX record, which plusnet did allow. However … Microsoft utilise SRV records for Microsoft Lync to work. As Plusnet do not support these, or allow the changing of nameservers to Microsoft’s own ( Ns1.bdm.microsoftonline.com and Ns2.bdm.microsoftonline.com), I had to move the domain to 123-reg.co.uk a free transfer and allowed me to update the nameservers
All this would have been nice at : http://www.plus.net/support/hosting/domains/domain_admin_dns.shtml !
