EWS Shared Mailboxes Sync Error

Hello,

i am using eM Client with Exchange Online. In addition to the main mail account i use some shared mailboxes. Sometimes i receive sync errors according to these shared mailboxes.

Error 1:
[Exchange Web Services] Die Syncronisation der Ordnerliste ist fehlgeschlagen mit folgendem Fehler: An internal error occurred. The operation failed.

Error 2:
[Exchange Web Services] Die Synchronisation des Ordners ‘Buchhaltung/Notes’ ist fehlgeschlagen mit folgendem Fehler: An internal error occurred. The operation failed.

eM Client Version: 9.2.2157

Using Outlook 365 doesn’t show anny errors on these mailboxes.

Any advice on this?

Best regards,
Michael
