Scenario: You are the owner of a Visual Studio Online account. You want to change the owner of that account. You try and see an error like this:
"Access Denied: XXXXX needs the following permission(s) to perform this action: Edit collection-level information"
Fix: Check your group membership. You can see this by…
• Logging in to https://<ACCOUNT>visualstudio.com/DefaultCollection/_admin/_security
• Click USERS in the upper-left
• Click on the account owner
• Click MEMBER OF on the right
In order to change the account owner you need to be a member of PCA (Project Collection Administrators) and TFA (Team Foundation Administrators). It is likely you are not a member of the latter, in which case the only resolution currently is to contact us here are support*. We will add you to the TFA group manually. In the future any member of the PCA group will be able to change ownership of a VSO account, but for now only the owner can do it.
