Several Mac users have reported an intermittent and infuriating problem with Apple’s Safari web browser when replying to messages in Zimbra web mail. Clicking Reply often results in a blank message window. Clicking in the message window does not get a text insertion cursor. However, closing the message window and trying to reply again usually works as expected. No amount of troubleshooting, short of using a different web browser, relieves the problem.
The Zimbra developers forum acknowledges that a lot of people see this problem when accessing the current version of Zimbra with the current version of Safari. Thankfully, you will not need to migrate all your bookmarks to Firefox or Chrome because there is a convenient workaround.
- After logging in to view your Zimbra web mail, click Preferences in the light gray tool bar.
- Click the Composing tab.
- In the Compose: section, select the check box for “Always compose in a new window.
- Click the Save button on the left side.
