How to subscribe to Office 365 IMAP folders
in flag

since about the beginning of November, I have troubles in using mail clients to access Office 365 mailboxes via IMAP. Specifically, it has become impossible to subscribe to IMAP folders, so that the MUA will only show "INBOX" and "TRASH"

As a workaround it is possible to configure the MUA to display all the folders it finds, regardless of any subscription, but this is clearly undesirable.

Finding resources about switching CIFS from soft to hard mount
ng flag

We have some NFS shares and smb CIFS shares mounted over TCP/IP on our RHEL 7 machine. The shares are part of a HNAS that sits on a VSP. As per default the NFS shares are mounted with the "hard" option (man nfs). For the CIFS the default "soft" option is set (man mount.cifs), their smb version ranges from 2.1 to 3.0. Now we are wondering whether it would be good to set the CIFS shares also to "hard".

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
