Are you not able to get new emails in the CRM or are not able to send emails?
Here's what may cause the issue.
To connect emails with Recruit CRM, your email service provider (Microsoft Outlook/Google) gives us a token that lets us sync your emails.
But, sometimes because of inactivity for more than 48 hours, the token sent by your email service provider expires. To make that token active again all you need to do is disconnect your email from Recruit CRM and connect it again. Here's how to do it.
Go to the email settings page here: https://app.recruitcrm.io/user/sync_email
Click on the "Delete" icon on the email settings. This will delete your email settings from the system
Depending on your email service provider (Microsoft Outlook/Google) Connect the respective email by clicking on the "Connect" button
PS: Once connected, your email sync will start which is a background activity. You can use the rest of the application and even send emails while the email sync is in progress.
Hope this helps!
