All of a sudden when using OWA/Exchange 2013 it takes forever to upload or download attachments. We did have a memory issue but I just doubled that. Now cpu utilization is at ~25-50% and RAM is at 50% w/ 24GB.

MB server: EXCH2013/CU8, 4 cpus, 24GB RAM, 600GB Database partition/95GB free disk space
We have 627 mailboxes on one MB server. Four of our five d/b's are ~115GBs, the fifth is 55GB.

Speedtests confirm full 50MB bandwidth up and down. No firewall changes. No new s/w installed. All I did do a lot the day before this issue arose was use the Exchange Shell a lot to delete emails in user's recoverable items folder--to free up space. I've done this a lot before with no issue.

No memory issues. Lot of memory. Lots of cpu util available.

Any ideas? Could the CAS or Edge server be causing this?
