Internt Explorer 11 iexplorer logon prompts

[morphict]

Hi guys,

So I am going a little bit crazy with this issue as it seems to be hit and miss with users.

 

Using the LA email address people are redirected to their logon on screen for office 365. However some of my users are prompted to enter username and password using the iexplorer prompt.

 

Good old Chrome and FireFox do not do this and I have gone through everything I can think of to stop it... They should be redirected to the federate signin form.

 

Please help before I go crazy
