If your Outlook PST file has become too large, this could be the reason. Large PST files slow down Outlook and cause frequent hangs. I found a solution to this problem with Softaken Compress PST Software. This tool easily compresses large PST files without any data loss. This improves Outlook performance and speeds up email loading. This software supports all versions of Outlook (2021, 2019, 2016, etc.) and reduces the size by extracting attachments. If your Outlook is also running slow, definitely try Compress PST Tool, a safe, fast, and reliable solution!
