how do I know wheich acct# is associated with the domains I have registered with MS office small business.

The billing page mentioins the acct #, the billing method and billing date, b ut NOT the domain name gthe acct# is associated with.

And there is no way to con tact MS for get the information from them.  Seems to me MS should have, at least, a live chatr help line.

Regarding "no way to contact MS," have you tried the email link to OL Support on the Find It page here?

You might make yourself a spreadsheet or use a notebook to keep track of your accounts. 

Hello, 

You can sign in to your Microsoft Office Live account using its Owner/Windows Live ID and go to the Domain Manager. You will be able to find the domain names and their status associated with your Microsoft Office Live account. 

 You can also contact the Support Team of Microsoft Office Live in this regard and confirm regarding the same.
