Microsoft has acknowledged a known issue that prevents some users from configuring their Exchange Online mailboxes in Outlook for Windows – but has not given a timeline for a fix.
As reported by BleepingComputer (opens in new tab)Microsoft has shared (opens in new tab) manual patch for IT administrators until a code patch is issued. The company also said the issue with Outlook, which is hosted email service for Business results from 603 error codes after a failed configuration process during the Outlook connection test.
Various Outlook clients are affected, including Outlook 2021, Outlook 2019, Outlook 2016, and Outlook for Microsoft 365.

Microsoft’s Exchange Online mailboxes are an enterprise-wide e-mail system similar to the service offered by Google Workspace. While it’s not the only thing Microsoft relies on for revenue, the fact that it brings in money at all may be why Microsoft is looking to provide a fix.
Microsoft claims that the root of the problem is that “Get-Mailbox will point the SharingPolicy to a deleted object.” While this is a serious problem that would benefit from an urgent fix, Outlook has had more than its fair share of important bug fixes through recent weeks for issues known since August.
Earlier in October 2022, Microsoft released a patch for Outlook for Microsoft 365 after it froze and crashed after launch. In early August, a bug that crashed Outlook email clients when reading emails containing tables (specifically Uber receipts) was also fixed.
However, Microsoft isn’t always so keen on fixing bugs in its software.
In the same month, it was dropped off at a micro-patch service 0patch to release an unofficial fix for a problem that allowed cyberattackers to bypass Windows’ Mark of the Web (MotW) defense mechanism, while one researcher accused Microsoft of “gaslighting” the security community after ignoring its efforts to disclose the problem.
While Microsoft remains on top of the Outlook issues, providing an ETA for a code fix could prompt similar sentiments from IT administrators.
