Outlook closes immediately upon opening

[aac]

Hi there

 

1 member of staff has reported that he is unable to open Outlook (2019) on his office PC. It closes immediately after opening. At first I thought just a profile issue however when this did not resolve it I noticed the issue appears no matter what PC he uses in school. We use Office 365 and had a similar issue a year or so ago for which the view mode had changed and once put back via Outlook web access fixed the issue but in this case settings via Outlook web access look to be normal. I have also noticed Outlook opens fine Outside of school using Outlook 365...

 

Thanks in advance

Can you open Outlook in safe mode?

Hi there, no safe mode caused the same issue. Luckily and after a few hours troubleshooting I have resolved the issue and it turned out to be a rule the user created causing an issue as I have turned the rule off in Outlook web access and now the Outlook app is loading without issue. Oddly I tried deleting the rule and it started crashing again so had to recreate it and turn it off to resolve the issue which is something I cannot yet and probably will never be able to explain.

Never seen that before with a rule and I've got loads on my mailbox. Odd.
