To access your email through your browser, you simply need to go to your webmail address. Your webmail address is typically setup to just add “webmail” to your domain name.
For example, if your website is http://www.companyxyz.com, then your webmail is likely http://webmail.companyxyz.com.
If you’re still having trouble, try logging in
at http://webmail.emailsrvr.com/.
