This issue can occur for a few reasons. Here's a quick list...
- Check Folder: Ensure you're not in the Junk or Deleted Items folder. These folders often restrict the "Reply," "Reply All," and "Forward" options.
- Reading Pane: Go to the View tab, click on the Reading Pane dropdown, and select Off. Sometimes, enabling the Reading Pane can cause these options to gray out.
Multiple Selections: If you've selected multiple emails, the options might be grayed out. Try selecting just one email.
Permissions: Ensure you have the necessary permissions to reply or forward emails in the folder you're working in.
