Outlook 2016 MAPI 80004001 Error


  • We are using Outlook 2016. When a delegate is trying to open a Principal's mailbox, he is getting MAPI 80004001 error. I tried to search on the web and in this community but only found MAPI error related to attachments and default mail programs. Thank you in advance!
