In this article you will find really working solutions for "Cannot start Microsoft Outlook" problem that will help you have your Outlook up and running again with no errors. The fixes work in all versions of Outlook and on all systems. A few articles ago we discussed what can be done when Outlook is freezing and not responding. Today, let's see how you can fix and prevent an even worse scenario when your Outlook does not open at all. "Unable to start Microsoft Outlook" error - causes and symptomsThe main symptom of this problem is very obvious and easily recognizable: you click Outlook's icon, an hourglass appears and is hanging for a while, and then you get the "Cannot start Microsoft Office Outlook" error. According to Microsoft, the major cause of this issue is a corrupted Navigation Pane settings file - profilename.xml, where "profilename" is the name of your Outlook profile. A good indication that the file is corrupted is when its size is 0 KB. No one knows the exact reason why this happens, but all versions of Microsoft Outlook from 2003 to the newest Outlook 2019 may be affected. Other reasons may be when you run Outlook in the compatibility mode, or if you are using a profile created in an older Outlook version, or if the Outlook data file (.pst or .ost) was deleted or damaged as the result of incorrect uninstallation or reinstallation of Outlook. Anyway, whatever the reason is, the outcome is the same - you cannot open the Outlook window because of this error: "Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened." There may be a few variations of this message depending on which Outlook version you use. Outlook 2010: "Microsoft Outlook has encountered a problem and needs to close. We are sorry for the inconvenience." Outlook 2007: "Cannot open your default e-mail folders. The information store could not be opened." Outlook 2003: "Cannot start Microsoft Office Outlook. Unable to open the Outlook window. Invalid XML, the view cannot be loaded." How to fix "Cannot start Microsoft Outlook" issue - universal solutionsNow that you know what causes problems on Outlook start up, let's see how we can get them fixed. Below you will find the troubleshooting steps for 4 most common problems that prevent Outlook from starting correctly, listed in order of frequency and efficiency: Recover the Navigation Pane configuration fileIn most cases it is the corrupted Navigation Pane settings file that prevents Outlook from starting successfully, so the first thing you need to do is to mend it. Here's how you can do this on different operating systems:
If you prefer to work with the Run dialog on Windows 7 or Windows 8, then follow this way.
Delete the Navigation pane settings file If for some reason you were not able to recover the Navigation pane configuration file, nor did the provided by Microsoft work, try to delete the XML file that stores the navigation pane settings. To do this, proceed with the following steps:
Repair your Outlook data files (.pst and .ost) using the Inbox Repair toolIf you have reinstalled Outlook recently and something went wrong during uninstallation of the previous version, the default Outlook data file (.pst / .ost) might have been deleted or damaged, which is why Outlook won't open. In this case you are likely to get this error: "Cannot start Microsoft Office Outlook. The file Outlook.pst is not a personal folders file." Let's try to repair your outlook.pst file using Scanpst.exe, aka Inbox Repair tool.

Turn off Compatibility mode in OutlookWhen it comes to using compatibility mode in Outlook, let me quote a wisdom that Outlook's guru Diane Poremsky shared on her blog: "If you enabled compatibility mode, disable it. If you haven't, don't even consider it." You can turn off compatibility mode in the following way:
If you still cannot open the Outlook window and the same "Cannot start Microsoft Office Outlook" error persists, try to restore the previous version of the PST file. Of course, in this case some of your recent emails and appointments will be lost, but it seems to be a better alternative than no Outlook at all. So, right click on the Outlook.pst file and select Restore Previous Versions. Create a new Outlook profileIf neither repairing nor restoring the Outlook.pst file worked, you can create a new mail profile in order to see if it solves the problem. If it does, then you can copy your current Outlook data file (.pst or .ost) from the broken mail profile to the newly created one.
If your old .pst file contains very important data that you absolutely cannot live without, you can try some third-part tools to repair your PST file, e.g. described in this article: Five reliable Outlook PST file repair tools. I cannot recommend any particular tool because luckily have never had to use any on my own machine.
