Share or Post button is grayed out when posting in Chatter from Internet Explorer
|Knowledge Article Number||000230559|
|Description||When attempting to Share a post in Chatter, or Comment on an existing post, the Share or Post buttons will gray out when clicked, and no post will be made. This behavior is only seen in Internet Explorer.
|Resolution||To resolve this issue, remove salesforce.com from the list of sites added to Compatibility View in Internet Explorer. Compatibility View is sometimes referred to as Compatibility Mode and is not a supported feature for use with Salesforce.
To disable Compatibility View with Salesforce.com:
1. Go to Tools (Menu Bar) on Internet Explorer 8, 9, 10, or 11. Alternatively, you can click on the gear icon in the top right.
2. Click on Compatibility View Settings.
3. Select the site and click Remove if salesforce.com is added to Compatibility View.
4. Click on Close and then refresh the page (F5, Ctrl R, or Refresh icon to the right of the address bar)
If you are unable to make changes within the Compatibility View Settings window, these settings may be enforced by Group Policy. If this is the case, please contact a System Administrator or your internal helpdesk for additional assistance.
Note: You might also have the checkbox "Display intranet site in compatibility view" enabled. Disabling this checkbox will resolve the issue as well.
