If you want to run MyCollab in the IntelliJ then you should follow the instruction in the above link.

If you want to run MyCollab outside the IntelliJ. For example, you customized MyCollab, and you want to create the zip file as you downloaded the MyCollab library, then you follow this link to create the zip file https://community.mycollab.com/docs/developing-mycollab/create-the-mycollab-installer/

Does it make sense?

It should send email well with the proper configuration. You should check this link https://answers.microsoft.com/en-us/msoffice/forum/all/configuring-javamail-to-send-mail-to-o365-exchange/46c6870c-4d7e-47c3-99f6-a6d19299e57d for the right parameters.

The notify should be the same with mail username because there are some mail providers don't allow you to use the from email different than the logged in domain.

You just install Mycollab as the installation instruction https://community.mycollab.com/docs/hosting-mycollab-on-your-own-server/installing-mycollab/. In case, you already use MyCollab and upgrade to the higher version, you just configure MyCollab use the existing database, it should works!

Could you download the MyCollab update fix https://github.com/MyCollab/mycollab/releases/download/Release_6.0.0/MyCollab-All-6.0.0.zip

such issue happens in several JRE versions. I hope this fix though I can not reproduce at our end but from Google

Could you give me the detail message in the error log, it should be in MyCollab home folder, has the mycollab.out in the logs sub folder. Thanks

it should have the process runs on port 8080. What is Os you are running?

If Linux : check command sudo lsof -i -P -n

If Windows: check this article https://www.howtogeek.com/howto/28609/how-can-i-tell-what-is-listening-on-a-tcpip-port-in-windows/

Or you can contact me via email hainguyen@mycollab.com. Thanks

You should go to the site again https://www.mycollab.com/ce-registration/ and fill the information, then it will download the binary immediately without sending an email. We think it is easier for users because some users also have the problem with the link in email

thanks! I am waiting your feedback

You should run MyCollab with at least Java 1.8, because we compiled the source to Java 1.8. So running in 1.7 will cause a lot of error or not running at all.

It seems this issue happens with some Java distributions (I searched over the internet) while I cannot reproduce on my side. I am investigating, could you share what java version you are using, OS. Thanks!
