Changing permissions cannot be saved in Outlook due to delegated access issues. Various add-ons and network access provider restrictions can also cause the problem. In this error, the user is unable to share a calendar or change the permissions for it.

A delegated access problem prevents Outlook from saving changes in permissions. The user cannot change calendar permissions or share it with another user because of this error. Network restrictions from access providers and various add-ons also may cause the issue.

In Outlook, delegate access is blocked while it is running, causing Outlook to fail to save changed permissions. It is also possible for network access providers to restrict calendar permissions or conflicting add-ons to cause this error. Users cannot change calendar permissions or share their calendars with other users because of this error.

Due to delegated access not working in Outlook, changing permissions cannot be saved. This error is caused by your ISP’s network access restrictions and other add-ons, as well as the user’s ability to share the calendar without being notified.

This is a common problem that occurs due to minor technical issues with the Outlook application. This problem has nothing to do with the hardware itself. Many users encounter this error on their system. If you want to fix this error, here are some effective steps.

What is the cause of the “Modified permissions cannot be saved” problem in Outlook?

  • Due to a failure or a lack of communication with the server, Outlook Calendar cannot save permission changes made by other users. Delegated access is used to share Outlook calendars with other people.
  • Delegated access is managed using the permissions in Outlook’s calendar properties. When permissions have been duplicated, conflicting authorization scripts are generated, which prevent Outlook from saving the permission changes.
