Hello all!
We have problem with Exchange 2010 and Outlook 2010 and Outlook 2013. We have big problem with storage and lose our previous database which work on Exchange 2010 and Server 2008. Now we install 3 server, 2 for DAG (with all roles) and for clients (HUB,CAS). Now we have problem with sent letters with big attachements like (30 MBytes). It seems like outlook wait 10-30 minut and after sent mail one by one, sometimes he sent only 1 letter of 3. All mails stuck in Outbox. Small letters very fast. If I work with IMAP, POP3, OWA all very fast. I check counters of prefomance - all perfect. All test Best Practic Analyzer says all ok, include perfomance test(2 hours) This problem and at work days and at night when no clients. Can some one help?
Totally we have 500 clients and now database nearly 200 GByte.
