iPhone syncs only a few Exchange notes after full resync

demouge

Hello,

I am using Grommunio with an iPhone 14 via Exchange ActiveSync.

My mailbox contains approximately 80 Outlook/Exchange notes. On the iPhone, only two notes are visible in the Apple Notes app under the Exchange account.

When I open the Notes app, sometimes a few additional notes appear gradually. However, the synchronization never completes and it eventually returns to showing only a very small number of notes.

I have already forced a complete ActiveSync resync for the device:

grommunio-admin user devices <user>@<domain> resync <device-id>

This did not solve the issue. After the resync, only two notes were synchronized again.

The Exchange account’s Notes synchronization toggle is enabled on the iPhone.

Could this be an issue in grommunio-sync / EAS Notes synchronization with iOS? Is there a recommended diagnostic procedure or configuration setting to check?

Environment:

Device: iPhone 14
ActiveSync protocol: 16.1
Grommunio Sync: 2.5.2.0d70954-lp160.35.1
Grommunio Web: 5.0.66.gc7c94cea8-lp160.685.3
Gromox: gromox-3.10.263.ma27b6be-lp160.59.1.x86_64

Thank you.

I have about 25 notes an all of them are on my iPhone 14.
Look for "loop" messages in the grommunio-sync log, I assume one message or note is damaged you need to find and delete this item.

I checked the grommunio-sync error log after updating to grommunio-sync 2.6.2.947f050-lp160.39.1.
The issue persisted and the log identified a broken note:

[ERROR] [maurice@domain.nl] Ignored broken message (SyncNote).
Reason: '2'
Folderid: 'U41ae3'
message id 'U41ae3:0a000000a5187b6fbcdcea1ed03c56570000000b0055'

There were also many repeated warnings during the same sync attempt:
Utils->GetFolderOriginFromId(): Unknown folder origin for folder with id '556164626163'

As I could not map the internal message ID to a visible note, I used the following workaround:

I copied the contents of all Outlook notes to Notepad++.
I deleted the original notes.
I recreated the notes manually in Outlook.

After recreating the notes, they now all synchronize correctly to Apple Notes on my iPhone.

This suggests that one or more of the original notes contained malformed or unsupported MAPI data, possibly originating from a previous import or migration. Newly created notes appear to work correctly with ActiveSync.

A safe method to identify or map the problematic internal message ID to the corresponding visible note would still be useful for larger mailboxes.
