Urgent Problem - Mails no longer showing or downloading body

I upgraded to V7 beta two days ago.

I cannot get the mails before then to download on one of my accounts that is office 365.

It says that it will be downloaded next time I go online. But I am online.

Hello Dominic,

To assist you with this issue, I first have to ask you to go to tools>settings>advanced>logging. Turn on logging for “Exchange Web Services” under your O365 account and when these errors occur, send the complete logs to adler@emclient.com

Thank you.
