OK, so we have 2 PC's. Both running Outlook 2010 and Windows 7 Pro x64.
They use an iCloud Calendar to schedule client appointments, make notes, etc.
If PC1 creates an appointment:
PC1 can open the appointment and edit everything but in the Subject and Location box, whatever is in there cannot be highlighted, Double click on a word will highlight the word but thats it.
PC2 can view/edit the appointment as normal.
If PC2 creates an appointment:
PC1 opens it but it opens as a Meeting view. You can input text in the notes box but the text is not there when it prints. Also unable to highlight anything.
PC2 it opens and works as expected.
I have tried removing all but necessary Add-In's, reinstalling Office, and uninstalling any nonessential apps
