How to delete a Team Project Collection in TFS 2017

Question

I have a Team Project Collection in TFS 2017 that is unused. It was created back, when TFS was new in our Company as a test. So there has never been real Code Checked in or anything. So I want to just delete. I couldn’t find out, how this works.

Answer 1

To delete a collection:

1. Detach the collection,
2. Delete the collection database
3. Delete the SharePoint site collection that supported the deleted collection.

Please see Detach or delete a team project collection for details, it's also applied to TFS 2017.

Answer 2

This is a high-level administrative task that can only be performed by logging into the Application Tier server and using the TFS administration tool.
