Question 1:
============================================
KB: 2997209. When an Exchange 2007 user accesses a delegated mailbox (proxy mailbox) on exchange 2013, the information store process of exchange 2013 may crash. If Dag protection is enabled, the database is automatically switched to another node. The reason is that after the patch is installed, the authentication method between exchange 2013 and Exchange 2007 has changed. When the user opens the proxy mailbox, exchange2013 fainted because he cannot understand the 2007 Verification Application... All these bugs...
Currently, there is no downloadable patch. If you need a patch, go to the case and ask Microsoft gtsc:

Question 2:
============================================
KB: 2997847. After cu6 is hit, if the mailbox is still not migrated on Exchange 2007, you exchange2013 will not be able to communicate with Exchange 2007 through proxy ActiveSync. The reason is that the verification fails between servers. However, this time, the storage will not crash because it is 2013 de-verification and 2007 verification, but the communication only fails.

Question 4:
============================================
If you find that after installing exchange 2013 cu6, OWA users cannot click a new email or reply to the email, please refer to the solution below.
Cause: the contents in the "V15 \ clientaccess \ OWA \ Prem \ 15.0.995.31" directory are not correctly copied during cu6 installation, leading to the lack of required files for OWA.
Solution:
1. Rename the "V15 \ clientaccess \ OWA \ Prem \ 15.0.995.31" Directory
2. Copy one copy from the previous version. For example, copy one copy from "15.0.995.29" to the new directory 15.0.995.31.
