We're often using user-email-accounts for shared inboxes / channels. However, we cannot use the calendar function as a "shared calendar". A support of this would be much appreciated because it also happens that we are using Gmail for user inboxes and Office365 for shared inboxes in some cases.
We utilize our shared calendar to manage team meetings and for visibility on time off- this would be impactful to have for my team.
This is critical for any entrepreneur with multiple emails and accounts. It'd be great to see everything in a single pane of glass.
