A Tip

Shares news about an underused Office feature: “If you go to this link and turn this on, the portal will be populated (over time) with all of your Office versions, additionally showing workstations that are behind on security updates.

You don’t need Intune for this either, I guess it works based on the UPNs logging into your tenant to the O365 Apps.

You can then also go into ‘Servicing’ > ‘Monthly Enterprise’ > and roll out the latest version to a set amount of PCs (or all) and set a deadline of, say, 1 day to get updated. You probably would not want to do that every month, but there is flexibility.

This may be old news, but I logged onto a dozen different clients and they did not have it turned on, so I guess not a lot of people know about it.

We shares a suggestion for organizing your documentation:

Use OneNote as a Knowledge Base! It has so many features that make using it as a KB so much easier than other forms like Word and PDF documents:

  • Integrated graphs for excel spreadsheets or stat tracking—Copy/Paste from Excel and it will automatically paste the entire spreadsheet correctly into OneNote
  • Built-in OCR for images posted anywhere in OneNote— OCR is native to OneNote, so take a screenshot, and all the words on that screenshot will be searchable!
  • Freeform formatting—You can type, draw, insert pictures or shapes, or almost anything anywhere on any page in the entire OneNote.
  • Collaboration—No need to share word documents anymore, you can give your team access to the OneNote and everyone can edit it all at the same time!
  • Organization—You can organize the KB by topic, section, or any other way you can think of.
  • Edit auditing—You can view the most-recent edits, who made them, and when they were made. No more trying to figure out who wrote the wrong thing in a KB!
  • Microsoft Teams Integration—You can add it to a Teams chat and access the KB on your phone, tablet, or anywhere else that you have access to Teams.
  • And more—Embedded files, links between pages/sections, notifications in each section for new content, the list goes on!

Every company I’ve been with so far had random KB folders full of documents or PDF’s, and I’ve always consolidated it into a OneNote. My coworkers and supervisors have always been impressed with the functionality that the OneNote KB provides, and loved the simplicity of putting everything in one place.”
