Using SM 12.3 with Windows 8 IE 11 and Windows 7 IE 11 on 3 different devices (client and our PC's), I found that if in any dialogue except Calendar I was unable to click the email tab and that the globalnewbutton was not displaying any options (new message, contact, appointment etc). I assumed it was a local issue with SM 12.3 so have today installed SM 13.1 to find I still have the same issue.

 

I have search the forum and also Google without finding any reference to this so I assume I have a local issue (my server). I found a knowledgebase article on " Usability Issues in Internet Explorer 11" but that said "applies to SM 11". I applied the changes anyway but that has not had any impact. Can anyone either corroborate my finding or suggest how I can fix this please? I don't like IE but I have to resolve it for the sake of clients who do. 

 

I also cannot explain why the email tab works when in the Calendar pane. I notice that in developer tools in IE that the email tab has an extra class of "active" in all the dialogues except the calendar one. Why is that?
