With the increased demand of Microsoft's online services, there had been adjustments made to Microsoft 365.  This month, Microsft has reverted some of those changes.  Read on for the details.

Here are a few updates. The changes previously announced are down below for reference.
 
Update August 8, 2020: Stream: The video search experience in Stream will temporarily exclude results from transcripts and search will not work for individual videos on the player page for the Singapore data center. Similar previously announced changes in other datacenters have been reverted.
 
New announcements:
 
The following temporary changes have been reverted:
 

• OneNote in Teams: read only
• Teams: frequency of presence checking
• Teams: typing indicator interval. In addition to being re-implemented, we have made additional improvements so that the first indicator is sent as soon as a user starts typing, and we show the typing indicator to the recipient for longer.

The below changes will remain in place for the foreseeable future. We will publish new Message center announcements if circumstances change:

• OneNote: Download size and sync frequency of file attachments has been changed.
• OneDrive Thumbnails: Customers who use OneDrive Files On-Demand and choose to "display items by using large thumbnails" in Windows Explorer or Mac Finder will see generic icons instead of thumbnails for a subset of file types, such as PDF and video files. Photo file thumbnails (jpeg, jpg, png, etc) are not affected by this change.
• SharePoint backend operations: We are rescheduling specific backend operations to regional evening and weekend business hours. Impacted capabilities include migration, DLP, apps that scan the service, and delays in file management after uploading a new file, video or image.
• SharePoint video resolution: Reduced video resolution for playback videos.
• Teams: video resolution.
• Stream: The video search experience in Stream will temporarily exclude results from transcripts for these data centers: Europe North, Europe West, Singapore, South East Asia, U.S. East. Searches will continue to show results based on words in the video title and description. Additionally, transcript search will not work for individual videos on the player page in South East Asia and U.S. East. Meeting recording video resolution adjusted to 720p.
