Outlook Classic Crashes
Office 365 Outlook crashes, tried creating data file many times still the issue persist. Data file - 100GB, Windows 11
Shabin, is the PST or OST 100 gigs? Either one is well beyond the limits of what Outlook can handle. 50 gigs is the limit. I would create a new Outlook profile and only download 1 year of data and that should download a manageable amount of emails/data from the server. Other things that can cause Outlook to crash is doing all the Office updates, Windows updates, checking your AV, firewall, VPN and web filters.
