01
A sync that never starts over
The delta query asks Microsoft only for changes since the last pass. Catching up stays fast even on a heavy mailbox, and read or unread state follows both ways.
Outlook synced without double entry
Kasar queries Microsoft through delta queries and pulls only what changed. Your messages, their read state and your replies stay aligned on both sides.
02
Sending from your own account
Messages leave from your Outlook address, not from a relay. Your correspondents see the sender they know, and the conversation continues normally if they reply from their phone.
03
Matching is automatic
Each message joins the contact record and, where it exists, the company one. People in copy are recognised along the way, which spares you discovering six months later that a decisive person never had a record.
Connect your tools, keep your habits
Connect your mailbox and calendar in two minutes, the history flows in on its own.
