How to Fix Cannot Change Working Time in Microsoft Project Web App

Product: Microsoft Project Web App (PWA)
Device & OS: not provided
Scenario: Attempting to edit working times or manage enterprise calendar configurations in PWA settings.
Observed behavior: The 'Change Working Time' exception name is unavailable, or the 'Enterprise Calendars' option is completely missing from PWA Settings.

Before you start

Solution 1Recommended

Request Administrator Permissions for Enterprise Calendars

Since editing enterprise calendars requires elevated privileges, you must contact your PWA administrator to grant you the necessary permissions to change working times.

In Microsoft Project Web App, enterprise data such as global working times and calendar exceptions are protected. Regular users cannot alter these settings to ensure organizational consistency.

If the 'Enterprise Calendars' option is missing, it directly indicates that your user account lacks the required Project Web App permissions or that an administrator has recently changed the group configuration.

Identify your system administrator

Locate the contact information for your organization's Project Online or Project Server administrator, typically found in your IT directory.

Request PWA Administrator access

Ask the administrator to add your user account to the appropriate PWA Administrators group, or to specifically grant you the 'Edit Enterprise Calendars' permission.

Refresh your PWA session

Once the administrator confirms the changes, log out of Project Web App and log back in to refresh your permission status.

Access Enterprise Calendars

Navigate back to PWA Settings. You should now see the 'Enterprise Calendars' option available, allowing you to edit the working time and exception names.

Request Administrator Permissions for Enterprise Calendars

Administrator Action Required: Only an authorized administrator can modify enterprise calendar configurations. If you are not authorized for admin access, you must submit your specific working time changes to the IT department for them to implement.

Frequently Asked Questions

Why is the 'Enterprise Calendars' option missing in my PWA settings?

This option is automatically hidden when your account lacks the necessary permissions to edit enterprise data, or if your PWA administrator has modified the site configuration to restrict user access to global calendars.

Can I change my own working time without admin rights in Microsoft Project?

You can change working times for local project files saved on your computer using the desktop app, but modifying enterprise-level calendars in Project Web App always requires administrative privileges.

How do I find out who my Project Online administrator is?

You can typically find your administrator by checking your company's IT contact directory, reaching out to your internal IT helpdesk, or looking up the admin contact details listed in your organization's Microsoft 365 portal.
