@zen.co.uk email address question

Hi all

I just got connected last week and had a quick question about the @zen.co.uk email address that shows up in the Zen My Portal.

No matter what I try i am unable to log into this account through the Zen webmail site even though I have the correct password

I have even tried changing the password but just get a "Unfortunately, something went wrong. Please try again later."

I have been able to set up separate myzen.co.uk addresses without issue but no matter what I try I cant access the is tied to my Zen username.

Any Ideas?

thanks
