BINXI-5831: Sync intermittently pausing or taking longer than expected

Version Identified

iOS Boxer 4.9

Identifier

BINXI-5831

Symptoms

All ActiveSync clients including iOS Boxer may sync intermittently or pause for mailboxes with very high volume or full calendars due to a server side issue in Exchange. In order to determine if a user is encountering this issue, navigate in the Boxer logs (Boxer > Settings > Support > Send Logs) and look for the following error:

"[TBAS] SYNC LOOP DETECTED for folder"

This error indicates Exchange has provided an incorrect response back to iOS Boxer, and iOS Boxer is attempting a workaround.
