Agree - getting this network issue fixed is business critical. New outlook can not substitute with such less functions. Please prioritize a fix and roll out asap.

Any update on this issue? I have a user that is having an issue connecting his Legacy Outlook

Hi,

the issue is still pending- Any update ? The New Outlook is unfortunately completely unusable for productive work and therefore not a valid answer or option.

Can you please communicate the expected fix time for this issue or workaround for users other than "wait ..." ?

Thanks in advance

Best regards
