I don't get this particular message like in the issue description, but with last NVDA alpha and outlook 365, I get lots of significant freezes while navigating the outlook interface. cc: @michaelDCurran, @SaschaCowley it might be that the last Outlook update throws a lot of UIA events to NVDA, no idea, but it seems the event limiter is somehow involved. Could you check this please? It seems Outlook got almost unusable in the last update.
My UIA for MS Word setting is set to "only when necessary", no NVDA add-ons in use.

Here are two log files from Outlook, maybe they are helpful.

Outlook-logging.zip

[seanbudd]

Can you confirm if this is the case for when UIA is set to: "Where suitable" and "Always" not "Where necessary"? It's likely your new Outlook version relies on UIA.

[seanbudd]

Welcome @munawarb ,

We are unable to process this issue as it stands.

• Please fill out the issue template fully. Tell us the full version number of Outlook and Windows
• Please reproduce this issue and provide a log file of the behaviour. Ensure your log level is set to debug in general preferences.

Kind Regards,
NV Access Software Developers

[munawarb]

@seanbudd NVDA debug log is attached. I had the log running while I opened Outlook and when NVDA froze until I dismissed the permission denied dialog.
I'm running office 365 Enterprise.

nvda.log

[gerald-hartig]

@munawarb can you provide more information on the exact version number of Windows and Office. Here are instructions:
Windows: https://learn.microsoft.com/en-us/windows/client-management/client-tools/windows-version-search
Office: https://support.microsoft.com/en-au/office/about-office-what-version-of-office-am-i-using-932788b8-a3ce-44bf-bb09-e334518b8b19

[gerald-hartig]

@munawarb it looks like your log file is missing some things. Can you provide a full unmodified log. If you're worried about personal information please email us the log.

[munawarb]

@gerald-hartig That's weird. I sent you the exact NVDA log after setting log level to debug. Is there a different level I should use?
