E-Mail fields link not working

Hi,

since I am loading all client static data from our host systems, I do not allow manipulation of this data in CRM. Therefore I lock all fields, where data is being imported, on the forms in CRM.

Unfortunately this has the side effect, that for text fields with format "E-Mail" the links are not working on the form :(

In case the fields are unlocked, the links are working.

Any idea how to workaround that?

Thx Thomas
