I'd like to know how do I delete the Conversation History folder on an Office 365 account?

I do not use Skype for Business, do not even use Outlook (I access the account for macOS Mail) and the folder is empty. Yet, I can't delete it from the web (the option is just greyed out) and on Mac it gives me the following error:

The operation couldn’t be completed. (MCMailErrorDomain error 1030.) The server returned the error: The operation couldn’t be completed. (MFEWSErrorDomain error 46.)

Does anyone know of a solution or a hack (using Powershell, etc) to delete or hide that useless folder for good? I have admin access on the account if that matters. I've searched around a little bit but most "solutions" I found are completely irrelevant.

Regards.

I've got a bit of an issue with Office 365 - after migrating an user from an existing IMAP account it seems like their "Archive" folder conflicted with the default one provided by O365 and as a result their existing archive is now named "Archive_0".

I would like to merge this with the main "Archive" folder but the issue is that we're looking at several thousand items - so much that Mac Mail is struggling to even load it (initial download took a good 10 minutes).

Is there a way to do it server-side, though some kind of API? I'd like to do it as a batch operation instead of downloading/uploading every mail which would take ages. Preferably I would like to use my Mac but would be able to install a Windows VM if necessary.

Regards.

I'm setting up a small business that will be providing internet service for a niche market. We'll be offering fully unrestricted and unmonitored (as much as the law allows - and while we'd rather not we will still have the ability to capture packets if justified) internet access, and I am not sure how should we respond to abuse reports (a Google search didn't find anything relevant).

Let's say I get an e-mail about SSH bruteforce coming from one of our customer's IPs. How do I tell whether it's genuine and not a troll (log entries and even .pcaps can be faked)? How do the big ISPs do it (for those that actually care about abuse reports I mean)?

Similarly, complaints about spam e-mail, how do I check whether they're genuine before acting upon them? Is this even a problem? Have there been instances where trolls would report someone for allegedly doing bad stuff in hopes of getting them in trouble with their provider?

Am I condemned to log every single packet leaving my network or is there an industry standard solution that doesn't go to such extremes?

Regards.

I've been trying for several days to configure dhcpcd to send a non-standard option to a DHCP server without any success. On the other hand dhclient works fine.

I need to send an option with code 90 which is a string specified in hex. The following dhclient configuration works fine :

option auth code 90 = string;
send auth 00:01:02:03...;

Yet I can't manage to do the same with dhcpcd. The manual quickly talks about custom options but it seems like those are for parsing DHCP replies and converting those custom options into shell variables then passed on to a shell script. What I'm looking for is to actually send a custom option to the server.

Does someone have an idea?
