Exchange
CLOSED
100%
Few minutes ago, Microsoft released a bulletin disclosing 4 critical vulnerabilities affecting Microsoft Exchange :
- CVE-2021-26855
- CVE-2021-26857
- CVE-2021-26858
- CVE-2021-27065

These vulnerabilities are affecting Exchange Web Service & Exchange Control Panel.
Since the patches may take few minutes to be applied over all the infrastructure, we took the decision to temporarily disable these features to protect our customers. Once the patches will be applied, the features will be re-enabled.

Thank you for your understanding.
