Synchronising your Microsoft Outlook Calendar with your CRM account


Please note: Supported Outlook versions are 2019, 2016, 2013, 2010 and 2007. To find out what version of Outlook you are using please click here.


Please be aware that Microsoft Outlook Exchange does not support this sync option because it is hosted on a server which behaves differently from the email client ‘Outlook’ which is supported on the above desktop versions only. 


It is really important that you advise us if your Outlook is Microsoft Outlook Exchange as using this sync method can potentially delete your calendar events.  We can set up a test calendar for you if you are not sure.


Pre Calendar Sync: 


1. Before we begin please contact our support desk with the name of your calendar(s) that you wish to sync with Outlook as we must provide you with the iCAL URL for each calendar. 


2. Please also make sure you have your CRM account login details to hand as you will need these as part of the set up process. If you do not know your password and you need to re-set your password please contact our support desk. 


3. Please also make sure you have done a back-up of your Outlook calendar as a pre-caution to any issues with the sync. Please click here to go directly to the Microsoft Support page to see how to take a back-up.

We cannot take responsibility if you choose to ignore this step and do not take a back-up of your calendar before using this 3rd party sync application.
