I have a User that keeps having Not responding issues in Outlook Client. The user has access and delegation to multiple calendars and can accept or decline meetings on others behalf. today the user schedule a meeting for their calendar and invited the users needed, some of these users are users they originator has access to accept on behalf of. The originator never received the Accept or decline email for the recipients, but did get a No Response Required one. the accept and decline email showed up in their inbox. What would cause this issue? also what would cause the user to keep getting the Not responding? User also has Meetings to update from other users calendars and some cases will take up to 4 minutes to open the meeting.

Things i have tried
Rebuilding the users outlook profile-
Have tried to repair the mailbox
we have gave the user a new windows machine with 32g of memory

The user can go to OWA and works fine but the functionality is not the same as the outlook client

Also the user will have email open on one window and the calendars open in another window.
