We are using Outlook 2013 with Office 365 and have come across an issue with emails that are received into the Inbox in HTML format are then being changed to Plain Text format when the items are moved to a Public Folder. If the item is moved back to the Inbox it also remains in Plain Text format.
We do not have "Use Cached Exchange Mode" switched on and cannot switch it on as we use terminal / Citrix servers.
Can you advise please as to what we can do to ensure that emails received in HTML format remain in that format even when they are moved to a Public Folder?
