Hi SV&&&,

Thank you for posting your issue on Microsoft Community forum. I understand that you receive this synchronization error log under the Sync Issues folder in Outlook.

May I double confirm whether you have any problem to sending/receiving emails or have any problem to delete/change any items by using Outlook/Outlook Web App? Please provide us with detailed information about the exact issue such as email sending/receiving (except this Synchronization error Log) for further analysis.

However, in most cases these errors are logged in the Sync Issues folder when the items no longer exist in the Exchange mailbox or the item was already deleted from the mailbox. If you don't have any problem to delete/change any items or sending/receiving emails. In these cases, the error can be safely ignored.

Regarding this point, we would truly appreciate your kind understanding.

Best regards,

Shyamal
