There are so many Windows 11 updates available that it’s nearly impossible to keep track of them all at the same time. Today, we’ll take a closer look at several changes that have a significant influence on the Outlook Mail operation.

If you start the Outlook Mail app and it crashes due to a memory or other problem, you should be aware that this is a widespread issue that affects many people.

With the help of its Windows Update mechanism, Microsoft was able to resolve the issue. Because there is no hotfix available, all you need to do is ensure that you are running the most recent version of your Windows 11 operating system in order for this repair to take effect.

If, however, you have installed the latest update and it still doesn’t work, let us see a few other workarounds that you can use to prevent Outlook from crashing, right after we understand what the differences between it and Gmail are.

What are the differences between Outlook and Gmail?

Outlook is a personal information manager developed by Microsoft Office, in which you can configure any email account you choose. It is included in the Microsoft Office suite, and in addition to sending and receiving emails, it allows you to save contacts, create tasks, and see the calendar.

The first distinction is that Gmail is an email service provider, which means that it offers the capability of sending and receiving emails. The Microsoft Outlook email client, on the other hand, is an email client that utilizes the services of any and all email service providers.

There are no such advantages and disadvantages of Gmail and Outlook as both have their own features, and you may choose which one to use depending on your needs.

However, there is a benefit to using Outlook which is that you may increase the security of your data by storing all of your email data in your system.

Because Outlook is a paid utility, there is no difficulty with the amount of space available in Outlook. On the contrary, you will only be able to store a maximum of 15 GB of data in Gmail.

What can I do if Outlook keeps crashing on Windows 11?

1. Disable add-ins

  1. Exit the Microsoft Outlook app, then launch Run by pressing the Windows key + R on your keyboard and type in Outlook/safe and click the OK button.

  3. Select the COM Add-ins option and click on the Go button.
  4. Click OK to clear all the checkboxes and restart Outlook.

It is possible that add-ins will cause your Outlook service to act in an unexpected way at times. Disabling add-ins may assist you in resolving this issue more quickly.

How can I send a secure email in Outlook?

The email encryption services provided by Microsoft Outlook are not as safe as you might think. This is due to the fact that Outlook encrypts email using S/MIME and Office 365 message encryption, both of which rely on the sender and receiver having the encryption feature activated on their computers.

When sending an email to a recipient who uses a platform that does not support S/MIME or Office 365 message encryption, you may not be protected from being hacked. The functionality required for email encryption is sometimes lacking in free clients such as those provided by Gmail and Yahoo.

You can use a separate encryption email service to ensure that all of your emails and attachments are totally protected. However, in this instance, you would lose access to all of the Outlook features on which you have grown used.

If you don’t want to deal with the hassle of switching email platforms, another more convenient option is to add an encryption service to Outlook through a third-party add-in. Nonetheless, you’ll want to be certain that the service you choose doesn’t introduce friction into the email process.
