Enabling guest access in Microsoft Teams: patience, patience…

I wanted to enable guest access in Microsoft Teams, in order to be able to invite external users to a team.

There are some interesting checklists and how-tos:

Microsoft Teams Guest Access checklist

Turn on or off guest access to Microsoft Teams

But the most important thing to know is in the second document: It takes 2 hours to 24 hours for the changes to be effective across your Office 365 organization. We are maybe not used to waiting anymore when it comes to IT stuff, but in my case it really took more than 15 hours for the setting to become active. So be patient :–)

Microsoft Teams for Mac: login fails with endless loop

I wanted to use the Microsoft Teams app on macOS to login to my personal Office 365 account, but I recently used it to login to my corporate account. That did not work out very well: Teams got into an “endless loop” asking me to sign in over and over again. It looks like Teams has some issues when switching between different accounts.

I got this solved by opening Keychain Access, and deleting the entry called Microsoft Teams Identities Cache. After that, I could sign in to Teams again with the correct account.

Password autofill on iOS with external keyboard

I recently got a Logitech keyboard case for my iPad. The thing works fine, but what was very annoying is that the iOS password autofill is not working when the external keyboard case is connected. It simply does not suggest usernames and passwords for sites where you have saved them in your keychain.

This is probably a security feature, but you can use the following workaround to access your saved usernames and passwords: go to Settings, General, Keyboards and activate the option Shortcuts.

Whenever you visit a logon page now for which you have saved your password, a small bar will appear at the bottom of your screen, with a Passwords button. Tap the button to access your saved passwords.

Convert a VMware Fusion virtual machine to VirtualBox on mac

I needed to convert a virtual machine created on VMware Fusion 9, to make it run on VirtualBox 5. To do that, you need to convert the virtual machine to the Open Virtualisation Format (.OVF).
These are the steps to accomplish this:

  • Locate the file of the VMware virtual machine you want to convert
  • Right-click and select Show Package Contents
  • Copy all these files to a new folder
  • Download and install the VMware OVF Tool. This is a command line tool that will do the conversion.
  • Open Terminal and execute the following command
    ovftool <source image>.vmx <target image>.ovf

    The conversion can take quite some time. For me, it took about 3 hours for a 140 GB Windows 8 image

  • Once the conversion is finished, open VirtualBox and from the File menu, select Import appliance

After the import, power on the VM, uninstall the VMware Tools and install the VirtualBox Guest additions.

Turn your old iPad into a digital photo frame

So you have an old iPad (like an iPad 2), and you think it would be a shame to just recycle it?

Why not turn it into a fancy wifi-enabled digital photo frame? This is what you could do:

  • Create a dedicated Apple ID for your frame, and configure your iPad to use that specific ID.
  • On the computer where you store your pictures, create a new Shared Album, and share it with the Apple ID of your iPad. If you want other family members to be able to add pictures to the iPad, share the album with them too.
  • On the iPad, install the LiveFrame app. It is free for testing (you can view the picture slideshow for 5 minutes, then you get adds), 2,29EUR to remove that limitation.
