I have a customer using Outlook for Mobile devices to connect to SmarterMail with ActiveSync. All of a sudden, beginning this morning he is getting the following error in Outlook for Mobile:
HTTP/1.1 403 Forbidden
To re-try press F9...
Error Code: 0x80004005
Everything seems fine in the SmarterMail ActiveSync logs but in the IIS Logs I find the following:
2015-10-09 20:38:55 W3SVC1 192.168.1.8 POST /Microsoft-Server-ActiveSync User=user%40domain.com&DeviceId=6F13EF5D46DE2A20&DeviceType=Outlook&Cmd=Sync 443 - 22.214.171.124 Outlook-iOS-Android/1.0 403 0 0 1541 520 31
This error has been repeating every 30 seconds since this morning.
We tried removing and re-adding the account in Outlook for Mobile but problem persists and tried adding the following to our web.config
<requestFiltering allowDoubleEscaping="true" />
Still problem persists.
Does anyone have an idea what could be causing this or how to fix it?
