I’m guessing it’s one of two things:
It could be two shortcuts to outlook. One might actually be Outlook classic.
Another issue could be a dreaded dual mailbox scenario that occurs when an hybrid on-premises user account gets a mailbox in exchange online before their on-prem account has its attributes created. It’s annoying to deal with and fix.
I’m curious as to what the issue is and how they fix it. I would assume that latency and bandwidth are a big problem and they have WAN acceleration going on, which can cause some apps to bug out.
I actually helped Riberbed identify and fix a bug with Exchange optimization that took 4 years to fix. The tech I worked with for about a year when we identified it called me up 3 years later to tell me himself that they fixed and closed it.














Store Outlook should be the same as Outlook, just with ads if not using a licensed account. I’m not sure how they are handling that, but I know they are trying to kill off all but one of the Outlook versions.
