@wale-A If you want to export all slides as JPG you can do it by using the Export method on the $presentation object. So it would be $presentation.Export($outputFile, "JPG", $width, $height).

$width and $height are optional parameters that you can use to specify the resolution of the exported image files. If not specified, the default resolution of 96 dpi will be used.

Have you had any success using this with O365? I think they have pulled the interop module.

I haven't used this script since 2017, but I just tried it with the current version of PowerPint.

I could not get the export to work, but the COM Interop API still seems to be in place, so in principle I think this should still work.

Thanks for trying. What version are you running? 2019? I'm Microsoft 365 Apps v. 2210 and I failed to load the assemblies. Read a few reports office had dropped the interop api.

I'm using the Microsoft 365 version 2210.

Which version of Powershell are you using?
Loading the Assembly seems to work fine on Windows PowerShell/PowerShell 5 but it doesn't work for me on PowerShell Core/PowerShell 7

Yes using powershell 7. Will see if I can use the windows version, it makes sense if the module isn't Net core compatible and needs all the Windows apis to work.
