outlook mail crashes fix

There are so many Windows 10 builds out there that it’s pretty hard to keep track of all of them. Today we are talking about a recent one which will bring some nice improvement to the Outlook Mail functionality. Read below for more details on this.

Microsoft has recently issued an important update which fixes some annoying problems for early testers of Windows 10. The problem is affecting Outlook Mail and on its official support page we see that Microsoft fixes the problems when it ‘might crash and not synchronize e-mail when running in the background in Windows 10 Insider Preview‘.

So, if you run Outlook Mail in Windows 10 Insider Preview, and it crashes due to a memory error, and does not synchronize e-mail when the app is running in the background, then you need to be aware of the fact that Microsoft has fixed this problem through its Windows Update feature. As there is not hotfix available, you just need to make sure that you’re running the latest version of your Windows 10 OS for this fix to take place.

In order to avoid such issues, you migh consider to switch to another mail service. In this case, we suggest you to check our list of best mail clients and apps to use. We are sure that you’ll find some interesting alternatives even it’s hard to change the mail service.

The problem has originally appeared with users running the first Windows 10 Insider Preview Build versions, but it could be present in other versions, as well. This update has been filed under the patch file KB 3069065, so if you spot that on your update list, then you should know what it refers to.

If you installed the latest Windows 10 Insider builds or the latest OS version for the general public (if you’re not an Insider), but you’re still experiencing Outlook crashes, here are some additional solutions to use.
