Answer 1

Don't use the prefix sp_ for user stored procedures as that is reserved for system procs.
Below is an example that returns the message using RAISERROR. A severity of 11 or higher as in this example will raise an exception in the application. Severity of 10 or lower will generate an informational message.
CREATE PROCEDURE usp_DeleteTeam #pTeamId int
AS
BEGIN
SET NOCOUNT ON;
DECLARE #Message varchar(2047);
UPDATE t
SET t.Deleted = 1
FROM Team t
WHERE t.TeamId = #pTeamId
AND NOT EXISTS ( SELECT 1
FROM [User]
WHERE TeamId = #pTeamId )
AND NOT EXISTS ( SELECT 1
FROM Account
WHERE TeamId = #pTeamId );
IF ##ROWCOUNT = 0
BEGIN
IF NOT EXISTS ( SELECT *
FROM Team
WHERE TeamId = #pTeamId )
BEGIN
SET #Message = 'does not exist in Team table';
END;
IF EXISTS ( SELECT *
FROM [User]
WHERE TeamId = #pTeamId )
BEGIN
SET #Message = COALESCE(#Message + ', ', '')
+ 'already exists in User table';
END;
IF EXISTS ( SELECT *
FROM Account
WHERE TeamId = #pTeamId )
BEGIN
SET #Message = COALESCE(#Message + ', ', '')
+ 'already exists in Account table';
END;
SET #Message = 'Team %d: ' + #Message
RAISERROR(#Message, 11, 0, #pTeamId);
END;
END;

Answer 2

Use the below SP to use print or select message.
Create PROCEDURE sp_DeleteTeam
#pTeamId int
AS
BEGIN
SET NOCOUNT ON;
IF ((NOT EXISTS (SELECT TOP 1 FROM [User] WHERE TeamId = #pTeamId)) AND (Not EXISTS (SELECT TOP 1 FROM Account WHERE TeamId = #pTeamId)))
BEGIN
UPDATE T
SET T.Deleted = 1
FROM Team t
WHERE T.TeamId = #pTeamId
SELECT 'Not exist - Table updated' AS Message
--PRINT 'Not exist - Table updated'
END
ELSE
BEGIN
SELECT 'Already exist - Table not updated.' AS Message
--PRINT 'Already exist - Table not updated.'
END
END

As far as I understood you just want to see if it executed sucessfully. If the stored Procedure is being called In some Applciation, At the end, Give a select statement as
SELECT 'Your message' AS Message
Then in application store the result in Dataset and retrieve your message,
If you are not using it in any application, then simply use
print 'your message'
OR may be try to be more specific and elaborate you problem a bit clearly.
