There is a programming error behind this.

That's what it's all about

  • At the turn of the year, mail servers all over the world suddenly went down.

  • The reason was actually the change from 2021 to 2022.

  • Because the mail servers could not handle this change due to a programming error.

  • Microsoft has now published a solution to the problem.

Exactly at the time when the calendar changed from 2021 to 2022, countless mail servers around the world went down. Those servers that run on Microsoft Exchange were affected. As a result, e-mails could suddenly no longer be delivered and administrators received the error message «Can & # x27; t Convert & # x27; 2201010001 & # x27; to long »is displayed. It is now clear that there is a simple error in the programming behind this.

Microsoft has now announced that the problem has arisen with the malware scan engine, which is used to check emails for malware, as reported by Stern.de. However, the fight against malware was not directly affected, it was much more likely that there was an error in the date check, which was caused by the turn of the year. “It's not a malware scanning or malware engine issue, and it's not a security issue. The version check of the signature file leads to a crash of the malware engine, which means that the messages get stuck in the queues ”, says the company.

Memories of Y2K

This was caused by a programming error. According to IT expert Joseph Roosen, the wrong data type was used on Twitter for the version number of the new signature at the start of the year. This can have a maximum value of 231 – i.e. 2,147,483,647. However, the new value is, which could not be displayed. Microsoft has now published a solution to the problem.

The mishap is reminiscent of worries about the so-called Millennium – or Y2K bug. At that time, IT experts feared that the change from 1999 to 2000 would lead to a failure of all possible technical devices. The reason for this was that many older programs used a two-digit number for the year. The concern was that jumping from 99 to 00 could cause the programs to fail. However, since sufficient preparations had been made for this changeover, the feared fiasco ultimately did not materialize.
