Because! No, because we have a strange issue that neither Barracuda (Spam Appliance) or Microsoft can figure out. We need all in/out mail routed through our Barracuda Appliance for compliancy reasons (encryption, content checking, etc). When an office 365 message gets sent out from Office 365 throug...

Correct, and that works just fine.

What i need is an O365 user that sends an email to lets say @yahoo.com. I need that message to flow through the Zimbra MTA and then out.

The Outbound connector back to Zimbra is just fine. Zimbra is just rejecting the relay. So I need to find a way to allow relaying from O365 through Zimbra. The O365 setup is straight forward and already done. It seems I can only relay by IP address. I know its not the best way to do it but is there ...

Hi all, We have a split domain and have had it working great for past 5 years or so. Traditionally we had mail flow from our 3rd party Spam/AV gateway > Zimbra > Office 365 and then for outbound Office 365 has a connector back to the Spam/AV. So in or out it all follows this flow.

Still having this issue. Support has confirmed its a bug (months ago) and that there is no workaround and no fix as of now. I've had to move a good number of users over to Exchange in order to get them a workable GAL. Anyone know how to escalate support issues? I opened the ticket back in April and ...

Anyone else having support issues? We've had paid zimbra support for years. In years past I've probably only reached out 3-4 times and ALWAYS had issues addressed pretty quick. Since upgrading to 8.8.12 I've had an issue where my GAL no longer syncs with any outlook users. Using EAS or ZCO doesnt ch...

Same issue however uninstalling an reinstalling is no longer working for me as it seems installer is bringing in the newest version. Also existing users are starting to get local failure notices with syncing issues.

OK, I have more info now. I was able to figure out how to do what I wanted. Just share it and then have the users add a new External Calendar to their calendar page and use the ICS address. Works great. Now, we have calendar's that we want ALL users to have regardless is there a way to automate addi...

Happy New Year! I have two separate Zimbra installs. One NE and one Open Source. My question is finding an easy way to share calendars between these two. Currently I can share between the two just fine however the user must click a specific link to do so and then must enter in a resource password, w...
