Does anyone know a way to hide email addresses on SharePoint - in particular when working or accessing a shared file - or to otherwise replace the email with a name?
Further details: Our volunteers are registered as external guest users on SharePoint in order to access the same files and folders, and will at times work on the same Word document. At the moment when they're on the same file, it shows their email address - which tend to be personal email addresses. I'd like to hide their email addresses from being visible to each other, or to replace it with a name rather than an email address e.g. Volunteer 62, so we could still keep a track of who has accessed a file, while retaining their privacy. Otherwise just to remove it from being viewed at all.
It's been suggested that:
We just set volunteers up with their own volunteer email address, but then this means we have to accept privacy policies on their behalf when creating them, while it can open a can of worms in them using the email in a way not linked to the organisation.
Don't use SharePoint - however this allows us to manage email access to external users, to provide Word to everyone regardless of whether they have their own personal copy, and options such as reviewing, and editing restrictions.
I'm not sure if there is a guidable solution with Microsoft's current setup, and their tech support are unsure themselves, so otherwise is it possible to hire a programmer/developer/coder to find a solution, or with its permission settings - is this impossible to do?
I've added some screenshots to help, but for protecting the volunteers I've blanked out the first part of the email.
