One of the mail databases on my client's server is corrupted, or a document in it, well, that's my conclusion after seeing this line in the log:
18/04/2023 17:37:40 Agent 'wAppointmentOpen' error: Instance member UPDATENOTICE does not exist
That's all the info there is...
I checked the mail template that's used for all mail databases, but none of the libraries containing a reference to UpdateNotice has been modified, they are still signed by Lotus Notes Template Development, dating back to 24 September 2013.
Is there any way I can discover which mail database needs fixing?? Luckily, there are only 20 mail dbs or so on this particular server, but imagine there are 1000 users...
