Recently my company has changed EXCHANGE servers.
I have been using CDO for years.
Now my emails are not being delivered.

I keep getting this message:
Remote Server returned '550 5.7.1 RESOLVER.RST.AuthRequired; authentication required'

How can I get around this?

Thanks.
 

Excel Facts

Which lookup functions find a value equal or greater than the lookup value?
MATCH uses -1 to find larger value (lookup table must be sorted ZA). XLOOKUP uses 1 to find values greater and does not need to be sorted.
