Here’s two Outlook for Windows bugs to watch out for. One is too easy to trigger and the other will affect people with a LOT of email to handle.
Copy bug with Input Method Editor
With Outlook 365 (classic) and using the Input Method Editor, Outlook might crash or hang when trying to copy text.
According to Microsoft this can happen with:
- Microsoft 365 for Windows, version 2409 build 18025.20096 or higher.
- when using languages with an IME (Input Method Editor).
The Input Method Editor is a way to use the standard QWERTY keyboard to enter characters for other languages like Hindi, Chinese, Japanese and many others. That means this isn’t an obscure or rare situation.
Workarounds
If affected, there are two possible workarounds. Essentially you have to get away from the affected software and revert to previous working versions.
Microsoft has a page about Reverting to a previous version of an IME (Input Method Editor).
Or rollback Microsoft 365 to an earlier version like 2408 (updatetoversion=16.0.17928.20156)
The fact that Microsoft is recommending both rollbacks suggests they aren’t sure which software is causing the bug.
Note: either of these workarounds might affect other software features, in particular the Microsoft 365 rollback.
See Microsoft’s Knowledge Base article for details and any updates.
Opening more than 60 emails makes Outlook crash
This is a beauty. If you open more than 60 emails at the same time, Outlook 365 might crash.
(We think this bug affects Outlook 365 (classic) for Windows but Microsoft’s report isn’t clear. Grrrrr)
If you have that many emails open you could get one of these error messages
“Sorry, we’re having trouble opening this item. This could be temporary, but if you see it again you might want to restart Outlook. Out of memory or system resources. Close some windows or programs and try again.”
Or
“Out of memory or system resources. Close some windows or programs and try again”
Workarounds
A few possibilities …
Don’t open more than 60 emails at once </obvious>
Change the registry entry for USERProcessHandleQuota (see User Objects – Win32 apps) from the default of 10000 (decimal) to a higher value (maximum is 18000). But this could cause trouble because the higher limit applies to all apps, not just Outlook.
Is this is a newly arrived bug? More likely it’s around for some time and just now come to Microsoft’s attention.
