I have moved a client from a pop3 service to a new hosted smtp service.
This problem I have come across before and there is a work around but is there a better solution.
When (sometimes) a user emails a colleague using the autofill in Outlook it at first fails, once the autofill is deleted and the address entered manually all works fine.
My question(s) are:
why does this only happen now and then?
what is being stored in the autofill?
is there a better way to tackle this than wait for the failure and then delete the autofill?
