The same syntax works completely fine when used in the "workflow service task" for email notification body

HTML syntax:  <a href="{/dataset/_task_link}">Please click here to start the recruitment process</a>

And it also redirects us to the actual form from the email but just doesn't work with email service task.

Hi Chinmay,

Did you try verifying both the Links ? I mean the task link opening on the forms inbox with the One you received via Email?

If Yes, you may try the same creating a reminder on the User Task tool instead of Email Service Task.

The {/dataset/_task_link} is only supposed to be used in the email notification of user task which will get the link of the current user task, if you want to include the link of a specific user task in a email service task, your Forms server need to be 10.4.5(https://support.laserfiche.com/kb/1014202/list-of-changes-for-laserfiche-forms-10-4-5) with which the link of any user task is available as a process variable as following and the inserted token will be like "{/dataset/_task_link[@_step_id=3]}", it can be parsed as the link to the specific user task.
