Turn on or off allowing content to be preloaded for meetings using Outlook


Skype for Business Online operated by 21Vianet in China will be retired on October 1, 2023. If you haven't upgraded your Skype for Business Online users yet, they will be automatically scheduled for an assisted upgrade. If you want to upgrade your organization to Teams yourself, we strongly recommend that you begin planning your upgrade path today. Remember that a successful upgrade aligns technical and user readiness, so be sure to leverage our upgrade guidance as you navigate your journey to Teams.

Skype for Business Online, excluding the service operated by 21Vianet in China, was retired on July 31, 2021.

Users can preload content, files, or attachments that are attached to an Outlook meeting invitation to a Skype for Business Online meeting, but you can it turn on or off. It's turned on by default for all organizations that are using Skype for Business Online. See how to Preload attachments for a Skype for Business meeting.


Currently, there are no cmdlets available in Skype for Business Online for setting or viewing online values for MaxContentStorageMB and MaxUploadFileMB. They are only available for on-premises deployments. It's important to know that content won't be uploaded to a meeting if the attached content exceeds the MaxUploadFileSizeMB or if the MaxContentStorageMB limit is reached.

Turning it on or off
