Seeing a certificate warning in Outlook often means your email client can’t verify the secure connection, and that can interrupt your work. The blog walks through simple checks like verifying your server settings and updating certificates, but sometimes the damage is already done to your PST file. An Outlook Security Certificate Error can leave your mailbox corrupt and unreadable. In that case, the MSOutlookHelp PST Repair tool steps in to rebuild the damaged file so Outlook can open it again. It lets you preview recoverable emails before repair so you only restore what you need, and it also recovers deleted items like contacts and calendars when possible.
