I run multiple email accounts and calendars on my labtop. All reside in Outlook, as part of my microsoft 365 office environment.
For unknown reasons my outlook calendar no longer allows me to select the correct email addresses to invite others to a calendar meeting. It no longer shows in the picklist. At the same time this email address is active as mail account in outlook.
I do not know how to repair this.
Where do I need to go in outlook to repair this?
