Error: Failed to open a log truncation context to source server ‘Ex2013_01.Mail.Com’. Hresult: 0xc7ff1004. Error: Error returned from an ESE function call (-1305).

on the target Server where the Database is Failing/ or being Added to...

1) Delete the Failing Database
2) Add the database copy : Add-MailboxDatabaseCopy -Identity DB2 -MailboxServer Ex2013_02 -ActivationPreference 2
3) You will see same ERROR: no worries
4) Go to the Database Folder location :  D:/Database/Logs
5) Move all the log files to another location
6) Open Exchange Management shell and run: Update-MailboxDatabaseCopy "DB2\Ex2013_02" -SourceServer Ex2013_01  -Verbose

and your database will start seeding...
