Hey Laodice,
Thank you for reaching out to us!
You could be facing this error message due to a discrepancy in the configuration set inside the Exchange ActiveSync policy. If the configurations of an O365 account are incorrect, the email application in your device will not be able to connect to the Exchange server successfully.
You can recheck the configurations that you have applied for the mandatory fields in the ActiveSync configuration policy. I can give you a brief on some mandatory/important fields in the policy:
- Domain – Enter the domain name of the exchange server.
- Account Name – Enter a name for the ActiveSync account. This name will be displayed inside the email application.
- Server Name – Enter the name or IP address of the ActiveSync server.
- Email address – Enter the email address of the account to be added.
- Username – Enter the sAMAccount name or email address of the account to be added.
- Password – Enter the password associated with the ActiveSync username.
The rest of the fields are optional and can be filled according to your requirement. For a detailed explanation on configuring the Exchange ActiveSync account, you can go through our detailed documentation on the ActiveSync configuration for Windows devices.
If you’re still getting an error message, you can reach out back to us. We’ll be more than happy to help you out.
Hope I was able to answer your query.
Cheers!
