ATP – Malicious file detected in a library – SharePoint, OneDrive & Teams

People regularly share files and collaborate using SharePoint, OneDrive, and Microsoft Teams. With Office 365 Advanced Threat Protection (ATP), your organization can collaborate in a safer manner. ATP helps detect and block files that are identified as malicious in team sites and document libraries.

How Office 365 ATP operates

When a file in SharePoint Online, OneDrive for Business, and Microsoft Teams has been identified as malicious, ATP directly integrates with the file stores to lock that file. The following image shows an example of a malicious file detected in a library.

Files in OneDrive for Business with one detected as malicious

Although the blocked file is still listed in the document library and web, mobile, or desktop applications, the blocked file cannot be opened, copied, moved, or shared. People can, however, delete a blocked file. Here’s an example of what that looks like on a user’s mobile device:

Deleting a blocked file from OneDrive for Business from the OneDrive mobile app

Depending on how Microsoft 365 is configured, people might or might not have the ability to download a blocked file. Here’s what downloading a blocked file looks like on a user’s mobile device:

Post to the Channel in Microsoft Teams by E-Mail

The reason I would see to send email to the Channel in Microsoft Teams, would be if its a long formatted email that you want to forward to all members in the channel to be aware of..

To do that, let’s get Channel’s email.. select the channel, you want to send email to, from the dots, a menu will appear, select, Get email address; as below..

And below how it should look like when posted to the channel by email;

Announce when callers join or leave could be noisy if thousands are attending

In a Live Event, with thousands of attendees, joining and leaving … if we keep this option “On” .. “Announce when callers join or leave”, it will be difficult to hear the presenter.

Here is how to disable it without going to Microsoft Teams Admin Center; in the meeting click, Meeting options; and besides “Announce when callers join or leave”; mark it as “No”.

Who really attended and who left in the middle … Microsoft Teams Live Event

The previous post, I showed you how to get an excel file with the list of attendees.. here I want to talk to you about the values of this excel file..

Basically, I was testing with my husband 🙂

The column header called “Action” has the status whether;

  • Joined,
  • Left
  • Reconnected
  • …..

Where you can filter this excel file and have an understanding of how people are participating all the time in the event.

Can’t wait! Upload your custom Image in Microsoft Teams


Microsoft confirmed with an update to the original Office 365 notification (MC208577) that they will allow Teams users to upload their own custom background images in May 2020. However, if you can’t wait, you can upload your own images today.

On the PC you are using, go to; %AppData%\Microsoft\Teams\Backgrounds\Uploads folder and you should be able to select those images for a meeting background.

Upload custom image for Microsoft Teams

I have uploaded large high-fidelity JPEG photos to this folder and been able to use them as a background, but it seems like resizing the background to 1 MB or thereabouts is a good idea. Apart from deleting the image file from the folder, there’s no way to remove it from a PC after it’s uploaded. If you use Teams on several devices, you’ll also find that images don’t roam across devices. You must upload and maintain images on each device.

On Macs, the images should be copied to:
/users/<username>/Library/Application Support/Microsoft/Teams/Backgrounds/Uploads

While Camera is on, change your background in MS Teams


Easy and straight forward … here is a screen of where to do that… yes notice you choose from these choices … having custom picture from your own computer or whatsoever is not yet…. but as of now here we have some professional and fun background pictures 🙂

Presence in Outlook & Workaround


If you uninstall the Skype for Business client after you move a user to Teams Only mode, presence stops working in Outlook and other Office apps.

Presence works fine in Teams.

Workaround: To see presence in Outlook (and other Office apps), Skype for Business must be installed, even if you’re running Teams in Teams Only mode.

Microsoft is aware of this problem and is working on a fix.
