You can always remove temporary files that may cause several disruptions in your system by going to the %temp% folder on your Windows device. Then restart your system and try again, if the issue still persists, then read the next step.

Cause 4: Windows Firewall blocking certain Outlook features.

Windows 7, 8, 8.1, & 10 comes with a pre-installed Firewall and Security feature that prevents certain viruses even ransomware to enter your Windows device, but sometimes, the hard rules applied by the Firewall to prevent virus attacks may cause third party user-installed applications to misbehave. Outlook.exe is an executable third party file for a firewall due to which firewall restricts its working and features.

Solution: Disable firewall for a short period, and then try again to execute your task. This will trigger the restricted activities and will allow third-party applications to work with full authority. Enable your firewall after your task gets over. Even after this, your issue is still intact, then see for the next point.
