I’ve been trouble shooting Office 365 e-mail (outlook) errors, for several months now.
There are many different errors, who need a different solution.
I’ve created a complete checklist for these problems.
I’ll hope you can use this list.
-
Is the problem only at one user, of does everyone have this problem?
-
Everyone, check your Office 365 Dashboard:
- Only one person, go to step 2
-
-
Open Outlook Web Access (OWA), is the problem also active in OWA?
- If so, contact Microsoft directly, because there is something wrong with this mailbox.
- If not, go to step 3.
- If so, contact Microsoft directly, because there is something wrong with this mailbox.
