The OST file isn't opening, and I'm getting errors repeatedly, but I want to access my emails through the browser. Is there any way to do this quickly via the browser, without needing Outlook for access to all emails? I am using Microsoft 365 for my email communication, and my complete Outlook data is stored in the OST file, but now, it is not opening. Suggest to me an excellent tool for accessing my OST file in a web browser format.
