Outlook Meeting Response Options are not visible for Invite

When you receive an invitation to a meeting in Microsoft Outlook, you might not see response options. This is because sometimes the recipient, upon opening a meeting invite, might not see response options.

Accept,
Tentative

Here’s how you can fix it.

Outlook Meeting Response Options are not visible

A user may find only the ‘No Response Required’ option displayed in the Respond section of the ribbon when they go to accept, tentative, or decline a meeting invite in Outlook. This is most likely due to a modification of data under a Windows Registry key.

To fix this, you’ll need to set the value of Disable Response Buttons to zero (0) in the non-policy section of the Windows Registry.

Go to HKEY_CURRENT_USER configuration
Navigate to the Calendar folder
Change the value of Disable Response Buttons to zero (0),

Open the Registry Editor by pressing Win + R to open the ‘Run’ dialog box. Then type ‘Regedit’ into the box and press Enter

When the Registry Editor opens, go to the following location –

Computer\HKEY_CURRENT_USER

Scroll down to locate the ‘Software’ folder. When found, click it to expand.
Next, scroll down to ‘Microsoft’ and then, Office > 16.0 > Outlook > Options > Calendar.
The path (16.0) depends on your version of Office.
Open the right pane of the Registry Editor and locate the following entry:”Disable Response Buttons”
Double-click this entry to open the Edit String box.
In the Value Data Field of the box change the value from 1 to 0.
Close the Registry Editor and Restart Outlook.

The problem should have been resolved by now, and you should now be able to see “Accept,” “Tentative,” and “Decline” options under the “Change Response” control in Outlook.
