How to Upload & Share Video on Microsoft Teams Windows 11?

Have you used Microsoft Teams for work or social contacts? In this article, we will teach you how to share pre-recorded videos on Microsoft Teams on Windows 11.

Microsoft Teams will get huge improvements in Windows 11, letting you chat with others on a variety of devices, like Windows 11/10 PC, Mac, Android, iPhone, iPad, and Chromebook. Considering you may have Microsoft Teams video upload requirement, this guide is mainly focusing on teaching how to upload video to Teams and share with others manually.

[Notice] Microsoft Teams Video Upload Limit & Supported Formats

  • Video upload size: up to 250GB.
  • Supported video formats: 2GP, 3G2, 3GP, 3GPP, ASF, AVI, BMP, HEVC, M2TS, M4V, MKV, MOV, MP4, MP4V, MTS, TS, WAV, WEBM, WMA, WMV.

Though most of the common videos are allowed to upload to Teams, exceptions including FLV, SWF and DVD discs need to be converted before uploading. Besides, based on my experience, even a MBs 1080p video needs a very long time to upload, so compressing the large sized video like a 4K file is necessary. If needed, Winxvideo AI may help convert the video format and downsize the large file.

After uploading, the members in your Teams chat will preview the video in the OneDrive cloud. However, OneDrive can’t play video if the video format is not supported by it.

The large file size and wrong video format are main reasons to blame if your pre-recorded videos can not be sent to Microsoft Teams or previewed in OneDrive. To be specifically, though Microsoft has increased the upload file size to 250GB for 4K/8K videos and other larger files, it doesn’t give any convenience as the upload process is very slow in speed, and even crashes sometimes. Besides, you have to convert FLV, SWF, DVD discs to MP4, MOV and M4V that can always be uploaded and previewed.
