Hi,
one of my cutomers has rented exchange online with O365. He has Problems with his email accounts.
He has configured those mail accounts on many different systems.
3 PCs and a few mobile devices.
Its 3 PCs with 3 mailboxes and 3 Phones/iPads. Each of them has all three mailboxes configured
Now Outlook on some clients can not access the mailbox and displays a waring that the connection could not be established.
I assume that MS has a hardcoded connection limit inside their exchange?
I can not get a hold of support by telefon...
So how do i fix this now?
Update:
This is one of the messages i get trying to sync the mailbox:
If i try to open the mailbox within outlook i get a message that the mailbox can not be opened becuase there is no premission to open it
Sometimes this works tho ...
I'll collect another screenshot of this when i speak with my customer
thx
