When you connect your Gmail or Outlook inbox to Fyxer for the first time, you may see an error message during authentication. Most issues come from Google or Microsoft permissions, not Fyxer, and can be fixed quickly by following the steps below.
This guide explains what common errors mean and how to resolve them.
Common Error Messages and What They Mean
400 / 500 Error (Microsoft)
A Microsoft-specific issue related to Outlook or Azure. This usually occurs when:
The Outlook platform is temporarily unstable
Microsoft rejected the authentication request
Your tenant has restrictive app permissions
Fix: Wait 10–30 minutes and retry. Use Outlook Web for best stability.
Rate Limit
Microsoft or Google temporarily blocked activity due to too many login attempts or too much API activity.
Fix: Wait 30–60 minutes and try again. Avoid repeated login attempts—this resets the cooldown.
"Error Connecting to Google"
Google rejected the connection. Common causes:
Duplicate or conflicting email identities in the organization
Attempting to connect using an alias instead of a primary email
Previously revoked permissions
Fixes:
Re-authenticate in an incognito window
Ensure you're using your primary Google account email
Re-approve access in myaccount.google.com → Security → Third-party apps
"Sorry, we're having trouble signing you in" (Microsoft)
Microsoft could not authenticate your identity. Usually caused by:
Domain mismatch (email doesn't match your Fyxer subscription domain)
Trying to join a different Fyxer organization
Incorrect or cached Microsoft credentials
Fixes:
Log out of all Microsoft accounts → retry
Ensure you're signing in with the email linked to your Fyxer account
Use Incognito/Private mode
Admin Approval Required (Outlook / Microsoft 365)
Your organization blocks third-party apps unless approved by an IT administrator.
Fix: Send your IT admin the screenshot of the approval request and ask them to allow access for the Fyxer app in Azure Active Directory → Enterprise Applications.

What Happens to my Folders when I Disconnect or Reconnect?
Fyxer no longer deletes or rebuilds your folders during reconnection.
If you disconnect your email, your Fyxer folders/labels remain in place
When you reconnect, Fyxer reuses your existing folders instead of wiping or recreating them
Your past categorization remains intact
This prevents data loss, avoids re-sync delays, and keeps your folder structure consistent.
Extra Troubleshooting Steps
These steps fix the majority of stubborn connection issues.
Try Incognito/Private Mode
Fixes problems caused by cached credentials or plugins.
Disable Browser Extensions
Security or privacy extensions can block auth windows.
Check Your Login Email
Make sure you are logging in with the same email registered to Fyxer. Using aliases can cause provider mismatch errors.
Verify Domain Match
If your organization uses domain restrictions, your login email must match the approved domain in your Fyxer workspace.
Revoke Fyxer Access and Retry
If credentials are out of sync:
Google → myaccount.google.com → Security → Third-party apps
Microsoft → portal.azure.com → Manage applications
Remove Fyxer → reconnect from your dashboard.
Use Outlook Web Instead of Desktop
Microsoft's desktop app is less stable for authentication. Switch to Outlook Web for initial setup.
What to Do If Your Password Is Correct but Authentication Still Fails
If login appears correct but Fyxer still can't connect:
Confirm you're logging in with the correct identity (no aliases)
Clear your browser cache or use incognito mode
Ensure your email isn't already tied to another Fyxer organization
Recheck permissions in Google/Microsoft
Retry connecting from the Fyxer Dashboard → Settings → Integrations
