General Availability of Adobe Acrobat Reader Integration with Microsoft Information Protection

Sorry if this is a repost but thanks for the help Rajneesh_Chavli. 

I'm able to log in now using user@domain.com but not email@domain.com.  I get the token error when I use email@domain.com.  I would like to have this fixed but worst case I can tell my users to use user@domain.com

However, I'm still having an issue with my test external gmail account.  I get an error "Selected user account does not exist in tenant 'Adobe Inc' and cannot access the application 'cad2910c-3b55-4610-ba7e-dda581063c91' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account."  If I close this window it opens up the pdf just fine and I can view it, but it doesn't go any further until I close the window.

This is an external user in my tenant and I have granted them permission to the application via the Azure portal.  I'm not sure what the 'Adobe Inc' tenant in the error message means.

This is an issue for us because we need to be able to share protected documents with external users.

Thanks,
