Active Sync not working

in Off-Topic
Users are unable to use active sync on their mobiles. I have setup OWA which is working fine with no problems, i followed the article "Publishing OWA Sites using ISA Firewall Web Publishing Rules (2004) OWA is also using Forms Based Authentication. My problem is that the users where able to sync before but now for some reason they cant. I checked the Exchange Server and within IIS and the settings seem to be correct, see below:
OMA: Authentication and Access Control = Basic Authentication.
Default Domain = \
Secure Communications = SSL has not been ticked and Ignore client certificates has been ticked.
Exchange Directory:
Authentication and Access Control = Basic Authentication and Integrated Authentication.
Secure Communications
SSL has not been ticked and Ignore client certificates has been ticked.
The error the user receives on their mobile is:
Support Code:0x85010001
Anyone have any suggestions. I have read some workarounds but feel that because AS worked before i should not have to do these.

What is the rest of your error message? There ought to be a sentence or two description of the error to go with the support code.
Recent: 11/2019 - RHCSA (RHEL 7); 2/2019 - Updated VCP to 6.5 (just a few days before VMware discontinued the re-cert policy...)
Working on: RHCE/Ansible
Future: Probably continued Red Hat Immersion, Possibly VCAP Design, or maybe a completely different path. Depends on job demands...
I have trid nslookup and both IP and Address has resolved successfully, so could it be permissions on the Exchange Directories? I dont know what they should be.
Any Ideas?
Did you say you have checked the permissions on the OWA > Microsoft-Server-ActiveSync directory within IIS?
What version of ActiveSync are you using?

These are mobile phones using Windows mobile 5 and active sync 4.1 ( i think) i cannot find where to find the version on the users phone)
As for permissions on the AS directory, what should they be? I have inherited this setup on Exchange so i am a tad lost as for the setup should be. I have followed some Microsoft examples but cannot find anything relating to the permissions.
