Is it possible to add Exchange custom attributes to users self-service portal and allow users to edit/modify them?
Background, we're looking at setting up Office 365 email signature tool however need to give staff the ability to add additional information, for example preferred pronouns, title, LinkedIn url etc.... The informaiton would be stored in the Exchange custom attributes (on-premise) and then synched to the cloud and available to the Office 365 email signature solution.
Understand how to add the additional attributes to the self-service portal with custom labels. But unsure if we need to modify the Exchange custom attributes permissions to allow the user to update or if we can use a scheduled task using a service account to perform the updates. We would prefer not changing permissions if possible.
