  Activesync does not sync public calendar, Is this normal. We need to give up using mdaemon connector because outlook 365 classic cannot find related messages. Active sync does one way sync, gets the entries of mdaemon connector users. But when activesync user adds something to public shared calendar these entries do not appear at others' public calendar.

  Unfortunately this sounds like the bug in Outlook where it won't sync events to the server using ActiveSync.  You can find more details here, https://learn.microsoft.com/en-us/answers/questions/4635093/activesync-dont-sync-events-created-with-outlook-w?forum=outlook_com-all&referrer=answers&page=1#answers. 

  The only work arounds that I'm aware of are to either downgrade to a version from before the bug was introduced (Version 2312), or switch to the 32 bit version of Outlook.

  Thank you Arron, 32 bit worked for me.

  I'm glad switching to 32 bit was an option for you.  Please also report the issue to Microsoft.  Maybe someday we'll get them to fix the issue.
