I'm having issues with some users being redirected to HTTP instead of HTTPS inside Zimbra NE. I have set the server to ONLY use HTTPS. Still, when some users try to, for example, change their password or send a shared calendar to external people, the URL being produced is HTTP instead of HTTPS. Obviously, that will produce an error as the server does not accept HTTP connections.
This sometimes also happens from the admin web GUI. For example, if I click "View Mailbox" from the accounts page, sometimes it opens it up as http://...
The strangest part of this behavior is that it doesn't seem consistent. Sometimes it works as expected, while other times not. It seems that some users are having this issue, while others are not.
I'm trying to figure out what I can do to make Zimbra ALWAYS open EVERY URL with the https prefix.
Any ideas anyone has are greatly appreciated.
Thanks in advance.
