Very rarely but sometimes people have the problem that they create a calendar entry in Pipedrive, but it shows up in Outlook in a different time zone.

This is obviously due to Outlook. Pipedrive has created an entry about this in the Microsoft Tech Community: https://techcommunity.microsoft.com/t5/microsoft-365-developer-platform/outlook-calendar-display-event-times-in-user-s-timezone-in-edit/idi-p/2920194#M430.

If you are concerned too, you could upvote there :) Then hopefully the friends from Microsoft will take care of it.
