I have been using a dynamics 365 trial account for learning. But when I tried to log in to my account last day, it showed an error as

"An error has occurred.

Try this action again. If the problem continues, check the Microsoft Dynamics 365 Community for solutions or contact your organization's Microsoft Dynamics 365 Administrator. Finally, you can contact Microsoft Support."

I logged in to the portal.office.com with my username and password, then selected dynamics then selected Dynamics 365 custom to load the application. Then it shows login successful. Then the error screen appears.

I tried it with another user, still the same error.

Hi Lu,

got the issue solved. It was due to the expiry of the trial account. Now extended the trial period for one more month.

Thank you for the effort taken. Thank you Ravi Kashyap for the suggestion.

Hi partner,

First of all, please clear your browser cache and cookies.

Then in the Microsoft 365 admin center, click Users, go to Active Users.

Select your username, and click Edit for Product licenses to see if there is Dynamics 365 P1 Trial for Information Workers.

If not, please re-apply for this Trial license.

Hope this helps.

Best Regards,

Hi Lu,

Thanks for the effort you took. I tried as you suggested me. But I could not find Dynamics 365 in the menu as you have shown me in the admin center.

This is what I could see in my admin center.

Thank you.

Hi partner,

Please check to see if your D365 trial is out of date.

Log in to https://admin.microsoft.com/, then click Admin centers on the left and select Dynamics 365.

Under INSTANCES in the Dynamics 365 Administration Center you can see the remaining days of your trial.

In addition, this is a generic error, does not really provide any info.

You could clean up your browser cache and cookies and try to log in on another computer.

Hope this helps.

Best Regards,

Hi,

Is your trial still active? Trials are generally for 30 days so if you are over 30 days that it may be disabled. If not, you need to contact MS Support to check your instance.

Hope this helps.
