iOS - Unable to complete a sync with Outlook.com since v11

I have an iPhone 16 Pro, been using emClient for years and exclusively for my Outlook.com account.

Since the upgrade to v11 about 1 week ago and the requirement to use MS Graph, the app has been unable to complete a sync with Outlook.com.

I’ve deleted the profile, re-added, no luck.
I’ve deleted the app, reinstalled, re-added the profile, no luck.
I’ve deleted the app, restarted the phone, reinstalled, re-added profile, no luck.

The app does begin to sync mail data initially, I guess it does it one time only and then hangs. From the initial sync, it will not allow any other mail to download.

Under Operations, I see my account in synching folder “/Inbox”. Progress bar is maybe at 5%, no errors, Logs show I’m ONLINE, sync is logged, but there is no completion of the operation.

Suggest then to go online into your Outlook.com account and “revoke the eM Client OAuth token” and then remove and readd the account again

Apart from that “just could be taking time to sync” depending on the size of your mailbox. Just leave it synching and see what happens.

There is also an updated V11.0.1140 just updated on the App Store as well you can try.

Under ‘Operations’, I have the following error since the MS Graph upgrade:-

[Microsoft Graph] Synchronizing folder ’ /Inbox’ failed due to the following error: The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. LineNumber: 0 | BytePositionInLine: 0.

I also have this problem with IpadOS. I had a message from Emclient to use Microsoft Graph, which I accepted. Since then it won’t sync. Windows and Android are fine so far.

I did just try revoking Em Client from Outlook.com app permissions.
Deleted the app, reinstalled V11.0.1140, re-added the account, approved the permissions.

Mail synced inbox and still stuck mid-sync. :confused:

Hi hazard and Geo1,

Sorry for the long wait on this one. Is the Outlook.com sync working for you now, or is it still stuck?

If it’s still stuck, please make sure you have the latest version of eM Client from the App Store. Then remove the Outlook.com account from eM Client and add it again. Your mail stays safe on the Outlook.com server, so nothing is lost. eM Client just downloads it again.

Let us know how it goes.
