Summary: Microsoft Outlook is a popular email client used by many organizations for email communication. Outlook, when configured with IMAP or Exchange server, stores mailbox data locally in an OST file. This file allows the user to access Outlook, even when the server or internet connectivity is not available. However, with all the impressive features that MS Outlook offers, it\u2019s not free from errors. Sometimes, you encounter errors while launching Outlook, such as \u201cFile access is denied\u201d. This particular error prevents the OST file from opening, and you lose access to your mailbox data.<\/strong><\/p>\n

Here\u2019s one such instance<\/a> of error reported by a user on the Microsoft community forum:<\/p>\n

CASE:<\/em><\/strong> I have users with an additional mailbox attached to their profile. When they try to access the mailbox by starting Outlook and choosing the necessary profile they are presented with the following error:\u00a0<\/em><\/p>\n

File access is denied. You do not have the permission required to access the file C:\\PROGRA~2\\Office14\\email@address.com \u2013 name. ost.<\/em><\/strong><\/p>\n

This error may happen due to various reasons such as you have Read-only permissions on OST, UAC settings not allowing access to OST, or the OST file is corrupt.\u00a0 We\u2019ve mentioned some solutions in this post that can help you resolve the issue.

[FIXED]: \u201cAccess is denied\u201d OST File Error When Starting Outlook<\/strong><\/h3>\n

Modify Outlook OST File Properties<\/strong><\/h4>\n

The first thing you need to do is check if the \u2018Read-only\u2019 attribute is disabled or enabled. The OST file Read-only attribute must be disabled. If it is not, follow the given steps to disable it:<\/p>\n

Step 1.<\/strong> Navigate to the path as shown below to locate the OST file on your system:<\/p>\n

C:\\Users\\%Username%\\AppData\\Local\\Microsoft\\Outlook<\/strong><\/p>\n

Step 2.<\/strong> Right-click the OST file, and choose\u00a0Properties<\/strong><\/p>\n

Step 3.<\/strong>\u00a0Uncheck\u00a0the Read-only<\/strong> box, click Apply,<\/strong> and then click OK<\/strong><\/p>\n

\"\"<\/p>\n

Now, try to open the Outlook and see if the error is fixed.<\/p>\n

Change UAC Settings<\/strong><\/h4>\n

User Access Control (UAC) defines the type of permissions to a different set of users on a file. Altering these settings on the OST file may help you fix the OST access denied error. To do so, follow the below steps:<\/p>\n

Step 1.<\/strong> Right-click OST file and click Properties<\/strong><\/p>\n

Step 2.<\/strong> Choose the\u00a0Security<\/strong>\u00a0tab and click\u00a0Edit
\n\"\"
\n<\/strong><\/p>\n

This opens a \u2018Permissions\u2019 window.<\/p>\n

Step 3<\/strong>. Click the\u00a0Add<\/strong>\u00a0button<\/p>\n

The Select User or Group<\/strong> window pops up.<\/p>\n

Step 4.<\/strong> Type\u00a0Everyone<\/strong>, click the Check Names<\/strong> button, and then click OK<\/strong><\/p>\n

Step 5.<\/strong> On the Permissions<\/strong> window, choose Everyone<\/strong>, tick the\u00a0Full control<\/strong> \u201cAllow\u201d\u00a0checkbox, and click\u00a0OK<\/strong><\/p>\n

Now, launch the MS Outlook and see if the error is resolved.<\/p>\n

Run Outlook as an Administrator<\/strong><\/h4>\n

Sometimes, launching Outlook with Administrative privileges resolves the Outlook access error. Follow the given steps to open Outlook as an Administrator:<\/p>\n

Step 1.<\/strong>\u00a0Type Outlook<\/strong> on Windows search box at the bottom-left corner of the screen<\/p>\n

Step 2.<\/strong> Right-click at Outlook<\/strong> application that populates<\/p>\n

Step 3.<\/strong> Choose\u00a0Run as administrator<\/strong><\/p>\n

Step 4.<\/strong> When prompted, grant permission by clicking Yes<\/strong><\/p>\n

If the issue still persists, this indicates that your OST file is corrupt. In such a case, creating a new Outlook profile sometimes helps fix Outlook OST issues.<\/p>\n

Create a New Outlook Profile<\/strong><\/p>\n

You can create a new Outlook profile\/account that may help fix the error \u201cFile access is denied\u201d. When you launch Outlook from the newly created profile, a new OST file is created.<\/p>\n

Steps to create a new Outlook profile on Windows 10:<\/strong><\/p>\n

Step 1.<\/strong> On Windows search box, type control panel<\/strong>, and click Control Panel<\/strong> that populates<\/p>\n

Step 2.<\/strong> Click Mail<\/strong><\/p>\n

Step 3.<\/strong> On the Mail Setup window that opens, choose Show Profiles

\n<\/strong><\/p>\n

Step 4.<\/strong> Click Add<\/strong> on the window that pops up, assign a name to the profile under the Profile Name<\/strong> text field and click OK<\/strong><\/p>\n

\"\"<\/p>\n

Step 5.<\/strong> On the window that opens, type your name, email address, and password (if you find a password field)<\/p>\n

\"\"<\/p>\n

Step 6.<\/strong> Choose the Email Account<\/strong> radio button, click Next<\/strong>, and follow the on-screen instructions to complete the process<\/p>\n

Step 7.<\/strong> Launch Control Panel<\/strong> once again<\/p>\n

Step 8.<\/strong> Choose Show Profiles, <\/strong>select Prompt for a profile to be used, <\/strong>and then click OK<\/strong><\/p>\n

Step 9. <\/strong>Try launching the Outlook and see if the error is resolved<\/p>\n
