Lately, some of our clients have had a number of challenges with Microsoft Outlook. The biggest issue seems to be mails being received after significant delays and Outlook showing an error message when mails are received from our Server.
The error seems to be in conjunction with Microsoft updates KB3837618 and/or 2837643. So far Microsoft has not eradicated this error.
Our support department can assist you with a solution. Unfortunately, the error can be one of a number of possible issues, which is why we cannot just send out a general guideline. The error will be corrected by one of our technical staff online. Since the challenge has been caused by Microsoft, the task will be carried out at normal support payment rates.2021-06-18 | Lars Kann
