If not help with the other way how to create outlook top Ribbon commands plug-in

<ExtensionPoint xsi:type="PrimaryCommandSurface">
          <CustomTab id="Contoso Tab">
          <!-- If you want to use a default tab that comes with Office, remove the above CustomTab element, and then uncomment the following OfficeTab element -->
            <!-- <OfficeTab id="TabData"> -->
            <Label resid="residLabel4" />
            <Group id="Group1Id12">
              <Label resid="residLabel4" />
              <Icon>
                <bt:Image size="16" resid="icon1_32x32" />
                <bt:Image size="32" resid="icon1_32x32" />
                <bt:Image size="80" resid="icon1_32x32" />
              </Icon>
              <Tooltip resid="residToolTip" />
              <Control xsi:type="Button" id="Button1Id1">

                  <!-- information about the control -->
              </Control>
              <!-- other controls, as needed -->
            </Group>
          </CustomTab>
        </ExtensionPoint>

      <ExtensionPoint xsi:type="ContextMenu">
        <OfficeMenu id="ContextMenuCell">
          <Control xsi:type="Menu" id="ContextMenu2">
                  <!-- information about the control -->
          </Control>
          <!-- other controls, as needed -->
        </OfficeMenu>
        </ExtensionPoint>

Answer 1

The PrimaryCommandSurface stands for the ribbon in Office. In case of Outlook we deal with read or compose items, so we should use the MessageReadCommandSurface for received items, for example:

<ExtensionPoint xsi:type="MessageReadCommandSurface">
  <OfficeTab id="TabDefault">
        <-- OfficeTab Definition -->
  </OfficeTab>
</ExtensionPoint>

The TabDefault is the idMso value of the built-in tab in Outlook.

Also you you can place controls into a custom tab in the following way:

<ExtensionPoint xsi:type="MessageReadCommandSurface">
  <CustomTab id="TabCustom1">
        <-- CustomTab Definition -->
  </CustomTab>
</ExtensionPoint>

If you need to get a ribbon UI displayed for the composed items in Outlook you need to use the MessageComposeCommandSurface extension point that puts buttons on the ribbon for add-ins using mail compose form:

<ExtensionPoint xsi:type="MessageComposeCommandSurface">
  <OfficeTab id="TabDefault">
        <-- OfficeTab Definition -->
  </OfficeTab>
</ExtensionPoint>

And to place controls into the custom tab:

<ExtensionPoint xsi:type="MessageComposeCommandSurface">
  <CustomTab id="TabCustom1">
        <-- CustomTab Definition -->
  </CustomTab>
</ExtensionPoint>

See the ExtensionPoint element for more information.
