Hi experts 

we are using exchange hybrid environment, i see this log in event id for every one second. and after an hour AD sync service stops and then i restart it but again after one hour service stops

 

The Microsoft Azure AD Sync service terminated unexpectedly. It has done this 1 time(s).
The following corrective action will be taken in 0 milliseconds: Restart the service.

 

when i click task manager i can see 150 proceses of AD-IAM HybridSync Master running 

 

2. how can i login to AD connect and troubleshoot ,  one of my friend said connect to Azure AD connect and run delta sync, how do i do

Hi,

 

First of all, what version of Azure AD Connect are you running?

Any changes done to the serviceaccount who handels the service?

I would look into upgrading the version or try a repair first at least.

If there is an issue with the service, I do not think a force of sync will help you.

 

But for future reference:

1. Logon to the server that Azure AD Connect is running on

2. Open PowerShell

3. Type in Start-ADSyncSyncCycle -PolicyType Delta to preform a delta sync.
