Zoho One Sync Tool - Troubleshooting

This document contains error messages you may encounter when you're setting up and using the Zoho One Sync Tool, and the methods to resolve those errors.
Some of the solutions will require you to check the Sync Tool's logs, which can usually be found at C:\Program Files (x86)\ZOHOCORP\ZohoOneSync\logs.

The error messages are listed based on the screen they appear in.

Zoho Sign-in screen

These errors will be shown if the Sync Tool was unable to sign you in to your Zoho One admin account.

Error
Reason
Solution
General Error

Delete the mapping, or add the custom field again in the Zoho One admin panel.

Bad Request
One of the mapped attributes has a value with incorrect formatting.

Check the AD attribute mapped with the mandatory custom field, ensure the attribute has some value, then try again.
Attribute length exceeded

Check the logs to find the attribute, ensure its value is within the accepted length, then try again.

Check the attribute's value for any inappropriate characters (e.g., alphabets in the "Phone" field), then try again.
Exists in another deployment

Request the user to close the other account, then try again.
