Here's a summary of the issue from your provided article:
Recently, users of Classic Outlook (especially on Virtual Desktop Infrastructure, or VDI) have experienced crashes when trying to open or create emails. This is particularly embarrassing for Microsoft because it seems related to their push towards the new Outlook client.
The root cause appears to be linked to the Forms Library, and it affects all channels of Microsoft 365 Office if running on VDI. Users running Outlook locally are generally not affected.
Microsoft has suggested a possible workaround: create a new folder called FORMS2 in the %localappdata%\Microsoft directory. However, this does not solve the issue for everyone, and some may need to use alternative ways to access email until an official fix is released.
This incident is one in a sequence of recent problems with Classic Outlook, including shared mailbox folder flickering. It has added to frustration among enterprise IT admins, with suspicions about the quality of recent updates (possibly even involving AI-generated code).
Summary of key points:
- Outlook crashes on VDI when opening/creating emails, linked to the Forms Library.
- Workaround: create FORMS2 folder in %localappdata%\Microsoft (may not work for all).
- No timeline on a fix from Microsoft yet.
- Locally run Outlook clients are mostly unaffected.
- Ongoing reliability issues with Classic Outlook in enterprise environments.
