AIP - external user only Microsoft Account

[gnoiret91]

Hello,

Can confirm me, for an external user of Tenant 365 and without invitation, when receive a file protected by an AIP Unified Label, the user can display the file if he has only an account create on https://account.microsoft.com/ ?

With my tests is Yes...

Thanks for your answers

Hello gnoiret91,

The user will need a subscription for Office apps or will need to download and sign in to the AIP UL client to open Office files.
Please take a look at this:

For PDF the user needs a supported PDF reader:

I hope this answers your question.
