Inviting users to your hub can sometimes result in errors or failed attempts. This guide will help you understand the possible causes of such issues and how to resolve them effectively.

 1. The user account belongs to a different data center   

The issue:

 The solution: 

• Ask the user to verify their current data center. They can do this by logging into their account and checking the domain (e.g., zoho.com, zoho.in).
  

• Invite them using an email associated with the same data center as your hub.
  

• Alternatively, the user can delete their existing account and re-register with the same email in the correct data center (if they are not using the account for any other services).
  

 2. The user is already a hub member   

 The issue:

 The solution: 

• Review your hub’s member list to confirm the user’s status.
  

• If the user needs an updated role or permissions, you can manage this from the Hub Settings panel instead of re-inviting them.
  

 3. Only 100 users can be added at a time   

 The issue: 

 The solution: 

• Split the email list into smaller batches.
  

• Ensure that no batch exceeds 100 email addresses, then try sending the invitations again.
  

 4. Upgrade your plan to add more users   

 The issue: 

Why it happens: 

• Visit the Subscription section in your Admin Panel.
  

• Upgrade your plan to increase the number of user licenses.
  

• Check how many licenses are currently in use before purchasing additional ones.

 5. Invalid email address   

 The issue: 

 The solution: 

• Review all email addresses before submitting the invitation.
  

• Use a spreadsheet tool to validate email format if inviting in bulk.
  

• Resend the invitations after correcting invalid entries.
  

 6. Maximum re-invite limit reached for this user   

The issue:

 The solution: 

• Contact the user directly to confirm if they received the invitation.
  

• Ask them to check their Spam, Junk, or Promotions folders.
  

• If they cannot find it, consider deleting the invitation and re-inviting them with a new email address.
  

 7. The user is already deactivated  

 The issue: 

 The solution: 

• Go to your hub’s Hub Settings Panel.
  

• Navigate to the Manage section in the users tab.
  

• Reactivate the user to restore their access instead of re-inviting them.

 8. The user has already requested hub access   

 The issue: 

 The solution: 

• Navigate to the Requested Users section in the Users section in the Admin Settings panel.
  

• Approve or revoke the user's access request as needed.

 9. The CSV file contains more than 100 emails   

 The issue: 

 The solution: 

• Open your CSV file and count the number of entries.
  

• Split the list into multiple CSV files, each containing a maximum of 100 entries.
  

• Upload and process them one batch at a time.
  

 10. Empty or invalid CSV file   

 The issue: 

 The solution: 

• Make sure the CSV file includes one column labeled Email Address and populated with valid email addresses.
  

• Avoid blank rows or unnecessary formatting.
  

• Save the file in .csv format and retry the upload.
  

 11. License usage for pending invitations   

 The issue: 

• If you no longer need to keep a slot reserved for the pending users, you can revoke their invitations, which will free up those licenses.
  

• Monitor and manage license allocation from your Hub Settings > Users > Manage.
  

• If you need to accommodate more users, consider upgrading your plan to add additional licenses.
