Outlook is a versatile application capable of managing multiple accounts from various email servers, including IMAP, POP, Exchange Server, and Office 365. Users are required to synchronize each account with the respective server and configure the necessary settings to enable message sending and receiving. Additionally, it is essential for users to keep their Outlook application up-to-date with the latest Microsoft updates, as these updates serve to optimize Outlook’s performance and enhance the overall email communication experience.
However, there are instances where certain updates can have adverse effects. Take, for instance, updates like KB2837618 or KB2837643 for Outlook. Upon installing these updates, users may encounter synchronization issues between Outlook 2013 and Office 365. These problems can persist even when the configuration is correct, as the updates may prove incompatible with Outlook 2013 and Office 365, leading to synchronization challenges.
The primary cause of the synchronization problem can be attributed to a security update, specifically KB2837618 or KB2837643. When these updates are installed, they have been known to trigger synchronization issues within Outlook 2013 and Microsoft 365. Even though the configuration of the IMAP account may be correctly set up, it may still fail to synchronize with Outlook 2013 or Microsoft 365. Microsoft has documented various issues associated with these updates, some of which users may encounter in their Outlook experience:
You do not have appropriate permission to perform this operation.
You do not have permission to move items in this folder.
Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.
After learning about the reason behind the synchronization issue and its outcome, now go through some manual procedures which can correct the matter and allow the Outlook to receive new messages.
If none of the aforementioned methods resolve the issue, the next step is to remove and then re-add the IMAP account in Outlook. However, it’s advisable to exercise caution when installing updates that may potentially disrupt Outlook’s performance. In more serious cases, the installation of problematic updates can lead to message corruption and render data inaccessible. To rectify this corruption, the ESEUTIL tool can be utilized for data recovery. To avoid finding yourself in such a situation, consider seeking the assistance of professional software solutions like Kernel for OST to PST converter.
