O365 Outlook hangs with in-cell editing on encrypted emails

Gpg4win help-en

Our O365 Outlook client has in-cell editing enabled. It works fine with all emails except encrypted ones. Entering any text in the cells of an encrypted email causes Outlook to hang. Removing the text causes it to behave normally again.

Gpg4win version: 4.2.0

Windows version: Windows 10 Enterprise version 10.0.19045 build 19045

Outlook version: Microsoft® Outlook® for Microsoft 365 MSO (Version 2302 Build 16.0.16130.20586) 64-bit

GpgOL log files are difficult to read but I think this is the relevant section:

Yeah I think that might never be possible in the way that we treat encrypted mails in Outlook, at least now while the mail is currently opened in a decrypted state. Much like the category and flag changes you cannot do while the mail is opened in a decrypted state.

But I have never tried it and at the very least we should bring up a descriptive error. I hope that I can try this out later today and will create an issue on dev.gnupg.org describing the problem.
