I success setup exchange 2016 active sync, but only my user account is able to send and receive email using mobile active sync and others mailbox are failed to do so.
I checked in exchange admin center (EMC) and their active sync is enabled. and they are able to access OWA as well.
I able to add the affected user profile into my phone but when i open the outlook apps it state connection to the server failed.
I checked in exchange server logs file, there's event id 1040,1053 that are related to activesync.
How can i troubleshoot this?
