We will explore the solutions for resolving the \u201cwhy Outlook won\u2019t open\u201d problem and the reasons behind this issue.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1850 aligncenter\" src=\"https:\/\/www.msoutlooktools.com\/blogs\/wp-content\/uploads\/2024\/08\/Cannot-Start-Microsoft-Outlook-Error-Alert-Box.png\" alt=\"Outlook won't open error\" width=\"496\" height=\"172\" \/><\/p>\n<h2>Reasons Why Outlook Will Not Open Up<\/h2>\n<p style=\"text-align: justify;\">If you are having issues with opening the Outlook app on your computer or laptop, there are certain reasons behind it:<\/p>\n<ul>\n<li style=\"text-align: justify;\"><strong>Troublesome Add-ins:<\/strong> Add-ins (or extensions) assist a program with additional features. Outlook, like other email clients, offers add-ins for enhancing email productivity. Many times, an added add-in (or extension) can interrupt Outlook\u2019s daily performance, leading to accessibility problems.<\/li>\n<li style=\"text-align: justify;\"><strong>Damaged Outlook Files:<\/strong> If any of the crucial App Files for Outlook get damaged, it may hamper app accessibility. Moreover, it may even lead to profile corruption in some cases.<\/li>\n<li style=\"text-align: justify;\"><strong>Corrupted Profile:<\/strong> Another reason for the \u201cwhy Outlook won\u2019t open\u201d problem is profile corruption. Factors like sudden system shutdown, oversized PST\/OST file, and app crashes may lead to Outlook profile corruption. This in turn causes Outlook accessibility problems.<\/li>\n<li style=\"text-align: justify;\"><strong>Virus Intrusion:<\/strong> Another reason why Outlook will not open is virus intrusion. An Outlook email may have a virus embedded in the attachments, and you may unknowingly release it into your system. Ultimately, it will disrupt your system\u2019s performance besides Outlook accessibility.<\/li>\n<li style=\"text-align: justify;\"><strong>Incorrect Configuration\/Installation:<\/strong> Another factor behind the Outlook app not opening is incorrect Outlook app configuration\/installation. Not following proper steps in configuring the app will make it function abnormally and even cause Outlook data file (PST\/OST) corruption.<\/li>\n<li style=\"text-align: justify;\"><strong>Outdated System:<\/strong> The system you use for accessing your Outlook emails may be outdated, causing the \u201cCannot start Microsoft Outlook\u201d problem. Suppose, you last updated your system a few months back, and you have recently updated the Outlook desktop app. The app won\u2019t function smoothly since you haven\u2019t frequently updated your system.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">Now that we have read the reasons why Outlook will not open, let\u2019s know the solutions to resolve this issue.<\/p>\n<blockquote><p><strong>Read More: <a href=\"https:\/\/www.msoutlooktools.com\/blogs\/import-ics-to-outlook\/\" target=\"_blank\" rel=\"noopener\">Methods to Import ICS to Outlook Calendar in Bulk [Solved]<\/a><\/strong><\/p><\/blockquote>\n<h2>How to Resolve the \u201cWhy Outlook Won\u2019t Open\u201d Problem?<\/h2>\n<p style=\"text-align: justify;\">The previous section explored the reasons for the Outlook app not opening. We will now explore the solutions to resolve this issue in this section.<\/p>\n<h3>Restart System and Outlook<\/h3>\n<p style=\"text-align: justify;\">The very first solution to resolve the Outlook app inaccessibility issue is simple: system and app restart. Restarting your computer\/laptop and then the Outlook app may help you access your emails and other data without problems.<\/p>\n<h3>Remove Faulty Add-ins Using the Safe Mode<\/h3>\n<p style=\"text-align: justify;\">If the first solution didn\u2019t help resolve the problem, then the next step is to remove the add-ins from the Outlook app. Since one of them may be causing the inaccessibility issue, it becomes important to remove it to fix why Outlook will not open.<\/p>\n<p style=\"text-align: justify;\">The following points mention the process of removing the \u201cwhy Outlook won\u2019t open\u201d problem through the problematic add-in\u2019s deletion:<\/p>\n<ul>\n<li style=\"text-align: justify;\">Open the Run command box (Windows + R) on your computer.<\/li>\n<li style=\"text-align: justify;\">Write the <strong>outlook.exe \/ safe<\/strong> command and click OK. (Ensure that there&#8217;s a space between outlook.exe and safe)<\/li>\n<li style=\"text-align: justify;\">The <strong>Choose Profiles<\/strong> dialog box opens up. Select the default app settings and click OK.<\/li>\n<li style=\"text-align: justify;\">Go to the <strong>File<\/strong> menu, select the <strong>Options<\/strong> section, and click on <strong>Add-ins<\/strong> in the <em><strong>Outlook Options<\/strong><\/em> window.<\/li>\n<li style=\"text-align: justify;\">In the <strong>View and Manage Office Add-ins<\/strong> window, go to the <strong>Manage<\/strong> box.<\/li>\n<li style=\"text-align: justify;\">Select <strong>COM Add-ins<\/strong> in the <strong>Manage<\/strong> dropdown menu, and click the <strong>Go<\/strong> button.<\/li>\n<li style=\"text-align: justify;\">Unselect all the Add-ins and click the <strong>OK<\/strong> button.<\/li>\n<li style=\"text-align: justify;\">Exit the Outlook app and restart it in normal mode.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">If this method works without issues, re-enable all the add-ins one by one and open the Outlook app to find the problematic add-in. Restart the Outlook app in Safe Mode and remove the add-in from the app to resolve why Outlook will not open.<\/p>\n<h3>Repair Microsoft Office 365<\/h3>\n<p style=\"text-align: justify;\">Another method to resolve the \u201cwhy Outlook won\u2019t open\u201d issue is to repair the Microsoft Office 365 app suite. It enables you to access the Outlook app after the entire Office 365 app collection gets repaired.<\/p>\n<ul>\n<li style=\"text-align: justify;\">Open the <strong>Control Panel<\/strong> and click on <strong>Programs<\/strong>.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1854\" src=\"https:\/\/www.msoutlooktools.com\/blogs\/wp-content\/uploads\/2024\/08\/Screenshot-2024-08-08-154643-1.png\" alt=\"open control panel and click programs\" width=\"956\" height=\"569\" \/><\/li>\n<li style=\"text-align: justify;\">Now, click on <strong>Programs and Features<\/strong>, and select <strong>Microsoft Office<\/strong>.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1855 size-full\" src=\"https:\/\/www.msoutlooktools.com\/blogs\/wp-content\/uploads\/2024\/08\/Screenshot-2024-08-08-154822-1.png\" alt=\"select microsoft office under programs and features\" width=\"1533\" height=\"562\" \/><\/li>\n<li style=\"text-align: justify;\">Open the <strong>Office Repair wizard<\/strong> by selecting the <strong>Change<\/strong> option by right-clicking on it.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1856\" src=\"https:\/\/www.msoutlooktools.com\/blogs\/wp-content\/uploads\/2024\/08\/Screenshot-2024-08-08-155025-1.png\" alt=\"click the Change option after right clicking on Office\" width=\"1007\" height=\"222\" \/><\/li>\n<li style=\"text-align: justify;\">The <strong>Office Repair<\/strong> wizard opens up with two options &#8211; <strong>Quick Repair<\/strong> and <strong>Online Repair<\/strong>.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1857\" src=\"https:\/\/www.msoutlooktools.com\/blogs\/wp-content\/uploads\/2024\/08\/Screenshot-2024-08-08-1552031.png\" alt=\"Office Repair wizard opens up\" width=\"975\" height=\"360\" \/><\/li>\n<li style=\"text-align: justify;\">Select the <strong>Quick Repair<\/strong> option and click the <strong>Repair<\/strong> button to start the repair process.<br \/>\n<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1858\" src=\"https:\/\/www.msoutlooktools.com\/blogs\/wp-content\/uploads\/2024\/08\/Screenshot-2024-08-08-155415.png\" alt=\"Select Quick Repair and click Repair button\" width=\"993\" height=\"359\" \/><\/li>\n<li style=\"text-align: justify;\">Restart the Outlook app after the Microsoft Office repair to access your emails.<\/li>\n<\/ul>\n<h3>Repair the Outlook Data File<\/h3>\n<p style=\"text-align: justify;\">If the previous methods couldn\u2019t resolve why Outlook will not open, another option is to repair the Outlook Data File. Microsoft Outlook has an in-built file repair tool, known as the Inbox Repair Tool (or ScanPST) with the scanpst.exe extension. This tool repairs the corrupted PST and OST files and removes the irrecoverable emails from the data file.<\/p>\n<ul>\n<li style=\"text-align: justify;\">Open the Microsoft Office installation system folder (C:\\Program Files\\Microsoft Office\\root\\Office). [The Microsoft Office version may vary.]<\/li>\n<li style=\"text-align: justify;\">Locate the <strong>ScanPST<\/strong> file and open it.<\/li>\n<li style=\"text-align: justify;\">Click the <strong>Browse<\/strong> button to add the corrupted PST\/OST file.<\/li>\n<li style=\"text-align: justify;\">Then, begin the file scanning process by clicking the <strong>Start<\/strong> button.<\/li>\n<li style=\"text-align: justify;\">If errors occur in the added Outlook data file, click the <strong>Repair<\/strong> button to repair the added file.<\/li>\n<li style=\"text-align: justify;\">Import the repaired PST\/OST file to your Outlook profile after the repair process.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">This method is capable of repairing Outlook data files but has certain limitations that restrict its complete usage. One drawback is it can\u2019t handle heavily corrupted files for repair.<\/p>\n<h4>Limitations of the Manual Solutions<\/h4>\n<p style=\"text-align: justify;\">Even though the methods mentioned above look perfect for fixing the \u201cwhy Outlook won\u2019t open\u201d issue, they fail to resolve the problem. Here are the reasons why Outlook will not open using these solutions:<\/p>\n<ul>\n<li style=\"text-align: justify;\">These <strong>manual methods are time-consuming<\/strong> due to the steps involved.<\/li>\n<li style=\"text-align: justify;\">Even though these methods look easy to use, <strong>they are highly technical<\/strong> (barring the first solution).<\/li>\n<li style=\"text-align: justify;\"><strong>Repairing the Microsoft Office 365 suite may not guarantee normal Outlook access.<\/strong><\/li>\n<li style=\"text-align: justify;\">The <strong>ScanPST tool works with only minor Outlook data file corruption<\/strong> and stops working with large-sized files.<\/li>\n<li style=\"text-align: justify;\">These methods <strong>don\u2019t guarantee complete rectification<\/strong> of the Outlook app inaccessibility issue.<\/li>\n<\/ul>\n<p style=\"text-align: justify;\">These limitations restrict the usage of the manual methods. How can Outlook users regain access to the Outlook app? Worry not! We will mention the perfect solution to fix the \u201cwhy Outlook won\u2019t open\u201d issue in the next section.<\/p>\n<h4>Professional Solution for Resolving the Outlook Accessibility Issue<\/h4>\n<p style=\"text-align: justify;\">Now that we have read the manual methods and their limitations, it\u2019s time to discuss the perfect solution here: automated software.
