A Rollup Update has been released for Outlook 2013. This is a non-security update which contains 14 documented improvements and fixes.
Most notable fixes are:
- Assume that you create a new conditional formatting that filters items by a specific category. In this situation, the conditional formatting may not work for the items that contain one or more categories except the given category.
- You cannot synchronize an Office 365 account in Outlook 2013. Additionally, you receive an “80040600” error message in the sync logs.
- Assume that you receive a meeting request in Outlook 2013, and the meeting request is created in Outlook 2016 and contains tables, or embedded images, or attachments. In this situation, the tables, or images, or attachments are missing or corrupted. To fix this issue, you’ll additionally need to set the AllowHTMLCalendarContent Registry value.
