No exchange 2007 in my organisation.
my organisation name is 2007 because this setup migrated from 2007 to 2013 that is why its showing legacy exchange name.
now  find out resolution.

i have 3 MBX servers ,MBX1 MBX2 and MBX3
MBX1 server there is no default database, all default database moved to MBX2 and MBX3. so when ever my db mounted in MBX1 issue persist.
if i moved mounted copy to either MBX2 or MBX3 owa accessible.

so i hope if i move one default DB to MBX1 issue will be resolved.

Please give suggession.

I think that is an incomplete migration, from 2007 to 2013. The 2007 information is still in your organization, and it should be removed and retired to get everything going as it should.

Hi Najmu,

If you shutdown Exchange server 2007 works? If you have problem with Exchange have not completely migrated and you need to continue with the migration process.
