Hi all

In OWA 2013 we try to manage customization in UIExtensions.xml as in previous Exchange 2010 OWA version.

Problem is that any new entries in <SmallIconMappings>, <RightClickMenuExtensions> and <NewItemMenuEntries> are not accepted by OWA.  Is there something new on background what needs to be set/changed to allow OWA work with this customization?

Any advise?

Thanks!

Same issue here! Any news about this issue?

I also have the same question.

We've realized that we have to create Office 2013 APP as standard customization solution for Exchange 2013 and O365 (https://technet.microsoft.com/en-us/library/jj219429.aspx).
