Why Bluemail Stops Working – 2025 Update

To resolve the BlueMail issue effectively, it is required to understand why it happens. Here’s what I found from recent reports and BlueMail updates:

• Due to background app restrictions, email syncs will be delayed.
• New features, such as AI/GemAI, lead to temporary bugs.
• Some email providers now require OAuth or block IMAP/POP3 for security.
• Corporate networks and VPNs can block ports BlueMail uses.
• Bluemail fails to launch on Windows and Android after certain updates.
• Incorrect folder mappings or outdated IMAP/POP settings lead to IMAP authentication failed issues.
• Missing emails when essential folders, i.e. Inbox, Sent, and Archive, aren’t selected for sync.

These are the main causes Bluemail stop working. Next, I’ll explain how to fix them.

How to Resolve Bluemail Not Working Issue – Step by Step

Now I’ll share the step-by-step instructions to resolve the query in minutes, i.e.

#Step 1. Identify the Problem

First, ask yourself these questions:

• Emails not arriving?
• Folders empty?
• Error codes like “IMAP disabled” or “Error 3011”?
• Did the problem start after an app update?

This helps you focus on the right solution instead of guessing.

#Step 2. Check Email Account

Most issues are account-related. So, first:

1. Log in to the email provider’s web interface, e.g. Gmail, Outlook, etc., to check credentials.
2. Make sure IMAP/POP3 is enabled.
3. Confirm permissions if OAuth or 2FA is required.
4. If it’s a work or school account, check with IT for policy changes.

One thing I recommend to my team, when they experience this error: if recently changed their email password, re-add the account in BlueMail after updating the password.

#Step 3. Test Your Network

Network issues lead to Bluemail not working, so:

• Switch between Wi-Fi and mobile data.
• Temporarily disable VPN or proxy.

If you find the IMAP folder is not properly syncing when VPN is off, then it is considered to whitelist BlueMail to fix the issue.

#Step 4. Fix OS Permissions & Background Settings

Modern mobile OSes block apps in the background by default to save battery and enhance performance. For the same, you have to turn off this setting via:

Android:

• Open the Settings option on your Android.
• Then, search for Apps > BlueMail.
• Select it, and click on Battery Usage > Allow background activity.

All the steps are the same across all Android OS, except the “Allow background activity” option; instead, you might see Auto Start, Allow background data, etc. But, when you enable it, whether to auto-start or allow background activity, restart your smartphone to troubleshoot Bluemail not working quickly. 

iOS:

• Open your iOS Settings.
• Search for BlueMail, and select it.
• Afterwards, hit the Background App Refresh, and ON.

If not resolved, then: Settings > Notifications > Allow alerts

Enabling BlueMail to run in the background solves most sync issues.

#Step 5. Clear Cache or Reset App Data

Sometimes old cached data causes crashes or empty inboxes. To clear them:

Android:

1. Go to your Android Settings.
2. Within the Apps option, navigate to BlueMail, and click on it.
3. Now, press the Storage and Clear Cache options.
4. If possible, Clear Data.

iOS / Desktop:

• Remove and re-add accounts inside the app
• Reinstall BlueMail if problems persist

This helps you to remove corrupted files.

#Step 6. Disable VPN or Proxy

When I use a VPN for work, Bluemail occasionally fails to sync, as the VPN changes my IP.

To test this, disable the VPN temporarily and check if the app works again. If it does, whitelist Bluemail in the VPN settings to fix the Bluemail not working error. 

#Step 7. Check Sync & Notification Settings

BlueMail won’t work properly if sync settings are wrong. To fix:

• Enable Push if supported, or set a reasonable Fetch interval
• Ensure folders like Inbox, Sent, and Archive are selected for sync
• For sending issues, verify settings:
  • IMAP Server: imap.domain.com, Port 993, SSL enabled
  • SMTP Server: smtp.domain.com, Port 465 or 587, SSL enabled
  • Correct email and password entered

#Step 8. Backup Emails for Data Continuity

Here’s a crucial step I never skip: backing up email data. I use the SysTools IMAP Backup Tool, which allows me to save all my emails locally in formats like PST, MBOX, EML, MSG, & PDF. 

It helps to back up all IMAP accounts, including Gmail, Outlook, Yahoo, or custom domains, directly to my computer. Additionally, it’ll support multiple IMAP accounts at once, so you don’t have to export each email separately.

Why Backup:

• If Bluemail stops working, you can still access all your emails offline.
• You have a secure backup in case of accidental deletion or server issues.

#Step 9. Compare with Another Email Client

If still facing the Bluemail not working issue, test the same account in Gmail or another email client:

• If it works there, the problem is in BlueMail.
• If it doesn’t work, the issue is likely with the email provider or network.

#Step 10. Reinstall BlueMail

If nothing works, reinstall it:

1. Uninstall the app, and remove IMAP account
2. Reboot the device
3. Reinstall from the official store
4. Re-add accounts one by one

This removes installation corruption and resets all settings.

#Step 11. Contact BlueMail Support

When all else fails, send logs to BlueMail support:

• Open Settings > Help & Feedback > Send Logs

BlueMail support will diagnose complex issues and resolve them as soon as possible.
