Office 365 mailto: Link Handler

Clicking a mailto: link will allow the user to select whether they want to use Outlook on the Web or the full blown Outlook.EXE client

I’ve been looking for a way to get mailto: links in websites open in Office 365 (Outlook Web) rather than the full Outlook client – as we have Outlook installed on our network, but unconfigured as everybody uses the web version.
I wrote something about 10 years ago which did this when we had a local Exchange box, although it’s since been lost as it no longer worked when we updated from Exchange 2003 to Exchange 2007. I’ve since written a new one which works with Office 365! Continue reading “Office 365 mailto: Link Handler”

Wake on LAN across subnets with HP switches

As part of setting up SCCM I wanted to get all PCs to wake-on-LAN to enable truly zero touch deployment. I’m using mostly HP v1910/1920 edge switches with a HP 5406zl core switch. To send WoL packets while testing I’m using a tool from¬†¬†(once all set up SCCM will be doing the wake on LAN packets).

I’ve since written a new post about Wake on LAN, which may be useful for troubleshooting.

Office 365 Automated Signature Generator

I’ve been looking for a while at a way to automate email signatures for everybody using OWA on Office 365. The new layout we want for our signatures includes images and everywhere I’ve read says it’s impossible to embed images in a signature set using PowerShell. (Note I want them embedded rather than hotlinked).

The solution I came up with takes details from the Active Directory user account – I’m using the description field to insert the person’s name (to allow things like “Mrs Blah” rather than just outputting firstname surname), fields like title (job title), telephone, mobile and also using a few of the extensionAttributes for the Twitter/Facebook links. All of these are standard fields so no need to mess with the AD schema. Continue reading “Office 365 Automated Signature Generator”

Windows 10, UEFI and PXE booting

Remember the good old days when Windows couldn’t change the boot order? Yeah…

I recently set up System Centre Configuration Manager to take over from MDT for imaging PCs. The end result I’m after is that all PCs attempt PXE boot when powered up, and then automatically image if there’s a task deployment waiting for them. (Bonus points is getting wake-on-lan to work with Win 10 so they’ll power themselves up too).

Thought this would be easy – surely just set network as the first boot device – only to discover that (on a UEFI booted system) part of Windows setup adds “Windows Boot Manager” and sets it as the first device in the boot list, no way to stop it. Continue reading “Windows 10, UEFI and PXE booting”
