Hi everybody,
Some time ago I've configured a SBS2011 server for one of my customers.
The SBS2011 has exchange and sharepoint, these services work fine.
The exchange server is only being used for the calendars, no e-mail flow.
The company uses IMAP through an external hosting-server.
So in Outlook 2013 we configure 2 accounts, one exchange account and one IMAP account.
Configuring the clients isn't a problem, and all seems fine, the calendar works.
But when the e-mail flow starts, users wil receive the same email multiple times and it seems the system is in a loop. E-mail flow will stop or the users get the same e-mails multiple times.
I've checked multiple solution regarding Win8+Outlook 2013 and IMAP, (issue about an update and setting the right root folder), but nothing seems to help.
We installed Outlook 2007 on the clients and configured them with both of the accounts and the system works like a charm! E-mail and the calendar are working like it should.
But the company bought about 20 Office 2013 licenses, so we need to get this to work on the new Outlook.
I don't think there is a problem in the Exchange Server, but in Outlook 2013, possible because both of the accounts share the same OST file.
Does anyone know how to solve this problem? Been running my mind for months.
With kind regards,
Tim Grave
