The integration features the following functionality:

  1. Creates meeting and reminders in exchange when they are created in ClickHome.
  2. Updates ClickHome meetings and reminders when changed in exchange (if they were originally created by ClickHome).
  3. Imports emails (the email subject should have job number).
  4. Imports email documents to save against job when sent as attachments (email subject should have job number).

Given a lot of companies now have Office 365/Exchange Online, there are some slight differences in set up. For Exchange Online you require minimum version v3.33.329.

If you have any issues or questions please refer your IT resource with all the details of your set up to and we can assist in troubleshooting. Otherwise you can contact your ClickHome consultant to request they undertake the set up

 Create Web Service Logins and permission

You will need to create the Exchange Web Services (EWS) login, and grant it permission to impersonate all users. Set up impersonation rights for Exchange Web Service so that you can read/make changes to exchange users. The EWS login used in this solution is clickmail. 

Exchange Server:

Get-ExchangeServer | where {$_.IsClientAccessServer -eq $TRUE} | ForEach-Object {Add-ADPermission -Identity $_.distinguishedname -User (Get-User -Identity clickmail | select-object).identity -extendedRight ms-Exch-EPI-Impersonation}


New-ManagementRoleAssignment –Name:impersonationAssignmentName –Role:ApplicationImpersonation –User:clickmail

This procedure grants "clickmail" user permission to impersonate all accounts on an Exchange Server. If you have any issues please check the Additional Information section at the bottom of this article.

Exchange Online:

This may have changed as Microsoft updates their interface menu options etc. The purpose is to give clickmail Impersonation access.
  1. Log in as administrator
  2. Go to the ‘Exchange’ Admin section
  3. In ‘Exchange admin center’ go to the ‘permissions’ > ’admin roles’ and choose ‘Discovery Management’
  4. On the ‘Discovery Management’ screen, "ApplicationImpersonation" role should be added and "clickmail" added as a member.

If you have any issues please check the Additional Information section at the bottom of this article.

 Log into the ClickHome front end and check the job for the new note.

Exchange integration gets executed in the background by ClickHome Windows Service. If the integration cannot access the account, the Ext.Ref. in Users>User Details > Settings is updated to 'INVALIDEMAILADDRESS'. This is done so it does not keep checking for an invalid account and to avoid creating spam.


 The reason the above field is updated could be any of these these

  • Change in the permissions for user account
  • Account becomes inaccessible
  • Any of the click home exchange configuration settings are incorrect
  • Cannot Impersonate the user account, verify if impersonation is set-up correctly

Once it updates this field, it does not check this account for new messages. When the issues are corrected, change the Ext. Ref. value to blank to start integration again for the user.

The appointments for Construction / Maintenance Supervisor are not showing up on the user's calendar

  • Verify if the click home user has exchange setting enabled (Administration > Users > Users> User Details > Settings section) 
  • Verify job is assigned to the supervisor (click home user)
