Two annoying problems in Exchange Online / OWA are:
– How to select another account ( the from field in Outlook ) ?
– How to see BCC when writing a new mail ?
2. Go to the Settings menu in the left / At message format section select Always show BCC and / orAlways show From ( depending of your scenario ), then click SAVE ( right-down corner ):
And if you encounter any problems feel free to comment / contact me.
