Maintenance work: Groupware service update

On 10.11.2022 between 9.30 a.m. and 5 p.m.

2022/11/10

+++Update: Maintenance work was completed at around 4:00 p.m.+++ Monthly security patches are being applied to the groupware service's Exchange servers today. (https://techcommunity.microsoft.com/t5/exchange-team-blog/released-november-2022-exchange-server-security-updates/ba-p/3669045)

Since at least one, previously unknown and severe security vulnerability, has been fixed, the patches will be applied before the regression tests. The functions supported by the HRZ will be tested in parallel with the supported clients (regression tests).

Due to the redundant setup, the groupware service will continue to be available during the update. Therefore we do not expect any problems for the users. There may be brief delays in access.
