I have a client that is based out of NYC. His assistant used to live in the area but has since moved to WY. So now she is a virtual assistant. She handles all his calendar emails and anything else. She has her computer set to EST to make things easier. She operates as him in an outlook on her computer. Over the last few weeks, she responded to some of the calendar invites as my client. The subject lists the time in MST. I have looked at her time and the time zones in Outlook calendar options. Everything is Eastern Standard Time on her PC. I am not sure where the issue is coming from. Finally, today, they emailed me a picture of the email saying it changed the timezone. Can anyone direct me to where to change this setting? Do you have any insight?
