All our staff mailboxes were on exchange 2007 and we built exchange 2013 and through hybrid set up we migrated all the mailboxes to 0365.
All the workstations have been installed with Outlook 2016 and successfully connect to 0363 mail
I have problem with one of the mailboxes. After I log in as the users and click outlook , it picks the profile and after some time it says , we are having trouble connecting to your account. verify the settings below...
Please see the snapshot and any help to resolve this would be great.
Thanks in advance,
