Hi Microsoft Team,
Good Morning. I can be able to send Outlook E-Mail (from 3 Mail Ids) to others using CDO in VBA. Now I renamed two of the Mail Id's and I couldn't be able to sent the E-Mails. The Mail was renamed some 1 week back.

`The following error has shown:

If I Change the Send SMTP Port Number : 587

For The Mail Id : axxxxn@pxxxxxxxxc.in (Microsoft 365 Business Standard) - Working
exxxxxry@pxxxxxxxxc.in (Microsoft 365 Business Basic) - Working
axxxas@pxxxxxxxxc.in (Microsoft 365 Business Basic) - Working

Now I Changed to the Mail Id's
axxxn@pxxxxxxxxc.in (Microsoft 365 Business Standard) - Working
axxxxxxxna@pxxxxxxxxc.in (Microsoft 365 Business Basic) - Not Working
cxxxxxxxxxxpraxxxxa@pxxxxxxxxc.in (Microsoft 365 Business Basic) - Not Working

Please give me a Solution for this.
