Aftab Alam Aftab Alam Updated On - 25 Oct 2019

An Outlook application can cater to multiple accounts from different email servers like IMAP, POP, Exchange Server, and Office 365. The user should synchronize each account with the server and apply proper settings to be able to send/receive messages. But, the user also needs to update the Outlook application according to the latest updates from Microsoft. These updates enhance the performance of Outlook and better email communication.

But sometimes there are some updates which make the adverse effect. For example, consider the updates like KB2837618 or KB2837643 for Outlook. After installing these updates, there may be synchronization problems with Outlook 2013 and Office 365. There may be no problem with the configuration, but the updates may remain incompatible with Outlook 2013 and Outlook Office 365 and create the synchronization issues.

The reasons behind the synchronization issues

The main culprit behind the synchronization issue is a security update (KB2837618 or KB2837643). Microsoft has mentioned multiple issues related to the updates. Here are some of them which you can encounter with your Outlook:

  1. The Outlook may crash soon after starting it.
  2. When the Outlook uses an IMAP email account, then the user may not receive new messages and get an error message like the following:
  3. You do not have appropriate permission to perform this operation.

    Or

    You do not have permission to move items in this folder.

  4. If the Outlook is connected with Exchange Server, then you may face multiple issues like:
    • The Outlook will give this error while you configure automatic replies-
    • Your automatic reply settings cannot be displayed because the server is currently unavailable. Try again later.

    • Outlook will not give free/busy data for calendar scheduling.

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.

Uninstall the updates from Control Panel.

  • In Control Panel, select Programs and Features.
  • Search for the updates KB2837618 or KB2837643 and double-click to uninstall them.
  • Restart the Outlook application and check if you are getting the new messages now.

  1. Open Outlook and follow File>>Account Settings>>Account Settings.
  2. Click the Change button.
  3. Click More Settings option and go to Advanced option.

Another method is to change the Account Settings in Outlook.

  2. uncheck the option – When displaying hierarchy in Outlook, show only the subscribed folders.

If any of the methods do not work to remove the problem, then you need to remove and add the IMAP account again with the Outlook. But, do not install such updates which hamper the performance of Outlook still. In severe cases, the messages may get corrupt due to bad installation of updates and the data will be inaccessible.
