PowerPoint
- We fixed an issue where the Notes Pane was in the wrong order with no ability to edit the slide when pressing the F6 key.
Word
- We fixed an issue where the Compare button was grayed out when a document was checked in and opened in desktop.
- We fixed an issue where base64 encoded .png images displayed the incorrect background color after switching folders.
- We fixed an issue where a document with "view only" permissions was able to be saved.
- We fixed an issue where the header of a document would disappear when enforcing Microsoft Information Protection (MIP) labels if the document was printed before selecting the label.

- We fixed an issue where the error message "You are attempting to open a file type that has been blocked by your File Block settings in the Trust Center." would appear when trying to open a file type marked for opening in Protected View, when Application Guard was enabled for Office and the setting "Open selected file types in Protected View and allow editing" was enabled.
Office Suite
- We fixed an issue where the File > Open dialog would not open when selecting Save As Picture to save an image.
