The reason I want to create an UPN is so the users can log on with their email addresses. &nbsp;<br />
<br />
e.g. logon is &quot;firstname.secondname@comp<wbr />anyname.lo<wbr />cal&quot; and <br />
email is &quot;firstname.secondname@comp<wbr />anyname.co<wbr />.uk&quot;.<br />
<br />

The reason I want to create an UPN is so the users can log on with their email addresses.  

e.g. logon is "firstname.secondname@companyname.local" and
email is "firstname.secondname@companyname.co.uk".

HI,<br />
<br />
Yes for this you can create the UPN suffix as @companyname.co.uk and change the same in users property in AD.<br />
<br />
So then the user can login with the email..<br />
<br />
let me know if you have any questions...<br />
<br />

Once you have created the UPN you will need to select it from the account tab on the user properties.

I've added the UPN suffix &quot;@companyname.co.uk&quot; and I can log on using this. I can also logon using &quot;@companyname.local&quot;. &nbsp;Why do you need to select the UPN in active directory user and computers if you can log on with both anyway?

I am afraid this you will have to ask Microsoft, but you can probably use both with OWA because one is your email address and the other is your internal UPN.<br />
<br />
If you added a 3rd I suspect (I have not tried it) it would need to be selected because it won't be your internal one or your email address.
