A Microsoft file hosting and synchronization service.
Hello Ricardo, Thank you for contacting us and I am sorry to hear you are experiencing this difficulty.
Given the Skype logout and the disappearance of the OneDrive folder, start by securing and verifying your Microsoft account as this is quite unusual.
I would recommend you change your Microsoft account password immediately if you suspect any security issues. Visit- https://account.microsoft.com/security and choose "Change password." Consider enabling two-factor authentication (2FA) for extra security.
While you're in your Microsoft account settings, verify the email addresses and aliases associated with your account to ensure they are correct and belong to you. Review any recent activity for signs of unauthorised access at https://account.microsoft.com/security.
As this is unusual, I strongly recommend you contact Microsoft support as they can help track down issues related to account access and potentially help identify which account was used for the missing OneDrive folder.
I hope this helps!
warm Regards, Ozi N
