How to Fix Zoom Error Code 3003 – Not Meeting Host



Zoom has soared to all-time high popularity thanks to the new normal that we are practicing right now. Everybody is working from home and that brought Zoom its highest number of users in its history since it was first launched as a video conferencing service.

Many have come to challenge Zoom including video calling platforms from Microsoft with Microsoft Teams and Google bringing in Google Meet. But, still, Zoom seems to be undefeated.

However, users recently complain about being bombarded by various kinds of errors when they use Zoom. One of these is the error code 3003.

What is Zoom Error Code 3003?

This particular Zoom error happens when a regular meeting participant receives an invitation link to be a co-host. When that user clicks on the link, the error is being displayed. This simply means that the person who clicked on the link is not a primary host.

The error message indicates “not meeting host. (3,003)”.

As we all know, the way a Zoom conference call works is that a primary host needs to set up and initiate the call. And then, the primary host can assign some of the meeting participants to be co-hosts. Every time a host adds a new co-host, Zoom creates a new link for the conference that is specific to that new co-host. That’s when the mix up happens.

Being the co-host of the meeting, they must share the new link created for them with the rest of the participants. But, that link is supposed to be used only by the new co-host and not by other meeting participants. That is the main reason for having the Zoom error 3003 which reads “not meeting host”. Technically, it is right because the co-host is not really the primary meeting host.

How do you Fix Error Code 3003 in Zoom Meetings

The solution to Zoom error 3003 is pretty simple and straightforward. You just have to change the link format a bit and then you can try joining the meeting again.

Zoom links follow a specific format and they look something like this: http://iu.zoom.us/meeting/123456789. All you have to do is copy that link and paste it somewhere where you can edit it and then follow these steps:

  • You need to change /meeting/ in the link to /j/. In our example, it should now look something like: http://iu.zoom.us/j/123456789.
  • Then, you need to use the new link and see if it lets you get right in that meeting.

Here is the meeting URL format to follow:


By changing the link to this format, you should be able to join the meeting without any problem.

Create a Zoom Co-host Designated to Start the Meeting

Change Host Zoom Meeting

Another way to set this up without going through that error is to create a co-host who will be designated to start the Zoom video meeting.

You can do this by following these steps:

  • Click Manage Participants on the meeting controls at the bottom of the Zoom window.
  • Select the name of the person you would like to be the co-host and click More.
  • Choose Make Co-Host.

By doing this, you have given the co-host administrative controls over the meeting. Which means, the co-host can start the meeting even without you, the primary host.
