While using Outlook, the user may experience the slowing down of the application and may face it more than often. There are various reasons why Outlook slows down like large-sized PST or oversize of data, outdated version, virus attacks, and many more. Let’s discuss those reasons in detail:

Top Reasons to Why Outlook Goes Slow

MS Outlook may go slow, when the connection cannot be completed due to an issue from the email provider’s end or if the password has been changed. Entering the wrong password can prevent Outlook to reach email servers. While trying to establish a connection, it keeps on sending the wrong password which eventually slows down the app.

MS Outlook may slow down due to the hardware acceleration setting also. Hardware acceleration is the technique to force a computer’s hardware to perform faster than the usual speed. However, this technique might slow down Outlook and the best thing to do in this case is to turn it off.

MS Outlook may slow down due to the add-ins. Many add-ins may be useful but cause to slow down the Outlook in case they are too many in number or they conflict with Outlook. Best is to disable them.

Finally, If the user has a corrupted PST or a large-sized PST exceeding the size limit, Outlook slows down or even freezes sometimes.
