If your Microsoft account is deleted, your entire chat and files (as well as those you shared with it) will be permanently lost. You won’t be able to access any previous chats, files, or conversations.
If you wish to remove your Skype account without deleting your Microsoft account, you must first unlink your Microsoft account. DISCLAIMER: It will take some time for the Skype account to be deleted from the database.
We allow for a 60-day waiting period before permanently canceling accounts in the event that you change your mind or need to access something before it’s erased. You may cancel the closure at any time during the 60 days by signing in.
An account is no longer visible on the contact’s end when it is deleted. We’ve been using Microsoft for a while, so we followed the 60-day waiting period before an account can be permanently erased. During the 60 days, the user’s account will continue to appear on his or her side.
Users may use the Skype free service as a guest user now, allowing you to begin chatting, filming or calling, and transferring files without having to create a Microsoft account or sign in with your Microsoft account. To summarize, you no longer need a Skype account to start using it.
