Hey Technet forums!
I wanted to create a quick TechNet question as I'm pretty stumped with an issue I'm having getting mobile devices to retrieve ActiveSync information from my Exchange server, but I'm noticing that the devices are connecting to, and getting basic responses from the server.
As a bit of background, I recently stood up a new lab-instance Exchange server with Client Access and mailbox roles after an older Exchange server I had was decommissioned (deleted and removed from ADSI/AD). The server itself appears to work fine. I am able to log into the Exchange server (OWA and ECP) with my AD credentials without any issues, and from there all Exchange tasks (sending/receiving email) appear to work fine as well. It's when I try to push this information to a mobile phone (Both iOS and Android OS's) that I see issues. When configuring my Exchange account on my mobile device, I'll notice that when entering the correct information, I'll receive 'Ok' prompts in the form of checks next to the server fields. If I proceed into the Mail app or try to gather other ActiveSync information, I will not be able to receive or send email. From there, when configuring the setup with an incorrect password or value for a field for instance, I will be alerted to that as well, prompting me that my AD credentials were incorrect or disallowing me to continue. Having these together leads me to believe that my phone can connect to the server and at the least receive responses, but the server is either refusing the connection, or there is a permission that I have not yet enabled.
As for any rules in ECP, I do not have any devices or users quarantined so that would rule that out. My default rule for ActiveSync is to allow any and all devices across the board as well. For authentication, I'm relying on just basic authentication (User Name & Passcode)
I've also attached a few snippets of code that I have from an email log of an Android device attempting to connect to the Exchange server. In particular, I'm noticing that I'm getting both 'Ok' messages as well as some error messages here. My question is, are these errors telling at all? From my research, it seems like the suggestion I've found here (Error code 111) is to simply try later. Please note, this error log has been stripped of other non-relevant information (such as MDM information) it can be reattached if it may help.

Additionally, I'm noticing that it seems like the devices are never registered on the ActiveSync server as well. When running the Get-MobileDevices command in PS on my Exchange server, I'm noticing that none of the devices I'm trying to connect are populating.
If there's any questions or requests for information, I will definitely provide that ASAP.
Thanks again Technet!
