Teams Storage

Question

We are planning a migration, is there a way to see how much storage My company has used only in Teams? I already have storage used for Sharepoints with Teams Channels connected, storage used for Onedrive and storage used for Exchange. How can I see the exact storage used for Teams from all users in the company? Are the files shared in a private chat end up just in Onedrives accounts storage?

Is it possible to migrate calendar meetings, private messages with all history to a new tenant?

Let's break down your questions one by one:

1. Viewing Storage Used in Microsoft Teams:

Microsoft Teams stores different types of data in different places:

• Files shared in Teams Channels: These are stored in the associated SharePoint sites.
• Files shared in private chats: These are stored in the OneDrive accounts of the users who shared the files. Therefore, there isn’t a direct report that shows Team-specific storage separately from SharePoint and OneDrive. You’ll need to consider the storage used in SharePoint (for Teams channels) and OneDrive (for private chats) collectively to estimate Teams storage usage. To get more detailed insights, you could use the Microsoft 365 Admin Center or PowerShell scripts to gather this information.

2. Migrating Calendar Meetings, Private Messages with History to a New Tenant:

Yes, it is possible to migrate calendar meetings, private messages, and their history to a new tenant, but it can be complex. Here’s a brief overview of the process:

• Calendar Meetings: Use tools like the Microsoft 365 Admin Center, PowerShell, or third-party migration tools (e.g., BitTitan MigrationWiz) to migrate calendar data.
• Private Messages (Chat History): Migrating Teams chat history is more challenging. Microsoft Graph APIs can assist in extracting and moving chat data, but this is typically beyond the scope of built-in tools and would require custom scripting or third-party solutions.
