I just migrated from iphone to an android Galaxy S3. I have two office 365 mailboxes setup with activesync, and one of them is working while the other one is giving me error messages such as:

Security update required - Update Security settings to use account

Unable to open connection to server: security error occured

 

I am receiving emails, but sometimes they stop and restart only if I click on OK at the notification screen for update security.

 

I have tried all the suggestions I found on the forum and elsewhere...

 

Sending messages from that mailbox also fails often but seems to work if I switch from WiFi to LTE!

 

So far I am unable to get a reliable send and receive functionnality on that mailbox.
