Hello

Thank you for contacting Microsoft Online Community Support. It is Mark, a
SQL Server Engineer. I'm glad to assist you with the issue.

For this case, you indicated that  the queries run OK even with the red
underline; you would like let the red underline disappear if the query is
right. Is it correct? If I misunderstand anything, please tell me directly.
It will help us to resolve this issue quickly. Once the issue resolved,
I'll appreciate your verification.

To better understand the issue, please help to confirm/collect the
following information.
1) what the queries are used to do? For example: to "select" or to create a
new table ? If it is convenient, please provide me  the sample of the
queries. I would like to try to re-produce the issue.

2) please tell me the confirguration of the intellisense in detail. Some
screen-shot will be better.

3) To narrow down the issue, please do the following test and tell me if
the intellisense recognize the table(under the table name, if there is a
red line). The detail  steps are below:
     a) open a new  query window
     b) choose a databse (master)
     c) try to type the command " select * from dbo.spt_values " and make
sure the table dbo.spt_values is from database  
          master

4) please tell me the version/edition of the SQL Server

Besides, if you would like to refresh the intellisense, please take the
following
Edit > IntelliSense > Refresh Local Cache

Besides, my email address is v-fathan@online.microsoft.com(remove the
online), you can send the information/test result via email.

If you have any questions or concerns, please tell/email me.

I look forward to hearing from you.

Thank you

Best regards,
Mark Han

It was supposed to be "menu" (bad typo I assume)...

Edit > IntelliSense > Refresh Local Cache

Questionable place for it, but I found out about it way too late to
complain.  :-\
