[German]Microsoft recently fixed a bug in conventional Outlook that caused problems when saving attachments. The problem has annoyed Outlook 365 users since July 2023 who wanted to save attachments to network shares. The saving processes took a very long time or aborted. Microsoft now claims to have fixed the bug, but is first testing it on a Windows Insider Preview version.

Slow attachment storing
I had addressed the problem on July 28, 2023 in the blog post Outlook: Microsoft releases temporary fix for slow saving on network paths. On July 24, 2023, Microsoft published the support article Outlook Desktop is slow to save attachments to a network path with an error description. If Outlook is configured to save attachments to a network path by default, the following dialog box Connection is being established may be displayed for a while before the "Save As" dialog box is finally loaded:g:
The dialog box informs you that the connection is being established, but this may take longer. Microsoft suggested a workaround at the time to alleviate the problem, which I outlined in the article linked above.
There is a fix for the bug
Microsoft has now rolled out a final fix for this bug, which leads to delayed saving, for Outlook 365. Our colleagues at Bleeping Computer noticed that Microsoft has already updated the support article Outlook Desktop is slow to save attachments to a network path as of November 8, 2023. According to Microsoft, this bug affects Microsoft 365 apps with the following build numbers:
- Current Channel: Version 2304 (Build 16327.20214)
- Monthly Enterprise Channel: Version 2304 (Build 16327.20324)
Microsoft has implemented a fix in Windows that will only be available to Insiders from build 25991.1000.rs_prerelease.231102-1335. This Windows 11 Insider build was already distributed in September 2023. However, it is currently unclear to me when the fix will be rolled out via an update for production systems. I've checked the support article for Windows 11 22H2 preview update from October 26, 2023 für Windows 11 22H2 (see Windows 11 22H2: Preview Update KB5031455 (October 26, 2023)), but have not found any mentions on a fix. So there is also no fix in the cumulative update KB5032190 from November 2023. Or am I mistaken?
