Microsoft Support and Recovery Assistant can help you resolve problems with Microsoft Office, Office 365, and Outlook. Editing file permissions and providing users with appropriate access is a simple way to solve such Microsoft 365 problems. Organizations value the capabilities that the Microsoft 365 suite provides for shared access and simultaneous file editing for team members. However, sometimes employees may not have the required permissions to open and edit an item.

One of the features of Office 365 is that users can work on their current Word or PowerPoint projects either on their mobile device or computer. As long as you’re working with your account logged in, the application should automatically save your progress on OneDrive and sync it to your device. However, errors can happen when the device is currently offline or not connected to a network. When you install Office it's automatically linked to your Office 365 plan.

Always define a recovery email address when configuring your Office 365 account. If an incorrect password is entered multiple times, after several unsuccessful login attempts, your Office 365 account will be locked. If your account is locked but you have not defined your recovery email address, try to fill Reset Microsoft 365 login credentials out the Microsoft account recovery form.
