Hello cemix,
Since the problem started after the migration and Outlook is working fine, this suggests that the issue might be related to the specific configuration or settings with AquaMail and the Zimbra platform.
Here are a few steps you can try to troubleshoot and potentially resolve the issue:
1. Check IMAP Settings in AquaMail
Reconfigure your IMAP settings: Ensure that the IMAP settings in AquaMail are correctly configured for the new Zimbra platform. Double-check the incoming server settings:
IMAP Server: Ensure you’re using the correct IMAP server address for Zimbra.
Port: Typically 993 for secure IMAP.
SSL/TLS: Ensure this is enabled for secure communication.
Authentication: Ensure that you are using the correct login credentials.
Force Re-sync: Sometimes, changing the server settings and saving them can force AquaMail to re-sync your email.
2. Clear App Cache and Data
Sometimes, sync issues can arise due to cached data. Try clearing the cache and data for AquaMail:
Settings → Apps → AquaMail → Storage → Clear Cache / Clear Data.
Re-add the account: After clearing data, you may need to remove the account and add it back to refresh the connection.
3. Check Folder Sync Settings
Ensure that AquaMail is set to sync all folders (including Sent, Trash, etc.). To do this:
Settings → Accounts → [Your Account] → Folder settings.
Ensure folders like Inbox and Sent are marked for synchronization, especially after a migration, where folder names or configurations may have changed.
4. Check Zimbra Settings
Zimbra might be using specific configurations that could be affecting syncing. Some things to check:
Folder Expiry Settings: Ensure that the email retention and expiry settings on the Zimbra server are not causing emails to be prematurely removed or hidden.
Time Zones: Sometimes mismatched time zone settings can cause synchronization problems. Make sure both AquaMail and Zimbra are set to the same time zone.
Synchronization Interval: Check if Zimbra has settings related to how often the sync happens or if there are any limits on the number of emails fetched.
5. Microsoft Exchange Migration
You mentioned migrating to Microsoft Exchange, but the problem persists. This suggests that AquaMail might not be syncing correctly with Exchange either, possibly due to a misconfiguration in the Exchange settings or an issue with AquaMail’s support for certain Exchange configurations.
Try reconfiguring the Exchange settings or removing and re-adding the account in AquaMail.
6. Verify Webmail Functionality
Since Zimbra webmail works fine, it’s likely that the issue is not on the server side but related to AquaMail’s interaction with the server. However, verify if any settings (such as flags or labels) on the webmail interface could be preventing full sync on AquaMail.
7. Test with Another Email Client
Since the issue is also present in the Outlook app on your phone, it would be good to test with a third-party email client (like BlueMail or K-9 Mail) to see if the same issue persists. If other apps work fine, this could point to AquaMail being the issue.
8. Check AquaMail Settings
Ensure AquaMail’s synchronization settings are optimized:
Ensure that Sync interval is set appropriately and that Push (if supported) is enabled.
Disable Battery Optimization: On Android, some battery optimization settings can interfere with email syncing. Ensure AquaMail is excluded from battery optimization:
Settings → Battery → Battery optimization and set AquaMail to "Do not optimize".
Let me know if you need further assistance!
