Increase the Archive and Index timeout following the next steps
1. Stop the MAM Search Service from the Windows Services.
2. In the archive sever go to C:\Program Files (x86)\Metalogix\MAMSearch\
3. Locate the file PamSearch.exe.Config and open the file with notepad or notepad++ (Make a backup of the file in case you need it)
4. Increase the archivetimeout and indextimeout to 600 in the next portions of the config file:
<Pam4Exchange><!-- PLUGIN -->
<servers>
<add server="97MAM1" archivedbtype="MSSQL" archivedbschema="dbo" archiveconnectionstring="Data Source=97DCDB1\SQLCI;Initial Catalog=MAMEXCH;User Id=sa;Application Name=PamSearch;" archivedbpassword="o/yyBWd+BY9MSiDuUjA9+Q=="
archivetimeout="600" indexdbtype="MSSQL" indexdbschema="dbo" indexconnectionstring="Application Name=PamSearch;Data Source=97dcdb1\sqlci;Initial Catalog=MAMINDEX;User Id=sa; " indexdbpassword="o/yyBWd+BY9MSiDuUjA9+Q=="
indextimeout="600" indexdirectory="C:\Program Files (x86)\Metalogix\MAMSearch\Index\Mail" />
</servers>
</Pam4Exchange> <ExchangeIndex>
<servers>
<add server="Legacy Index" archivedbtype="NOTSET" archivedbschema="" archiveconnectionstring="" archivedbpassword="" archivetimeout="600" indexdbtype="MSSQL" indexdbschema="dbo" indexconnectionstring="Application Name=PamSearch;Data Source=97dcdb1\sqlci;Initial Catalog=MAMINDEX;User Id=sa; " indexdbpassword="o/yyBWd+BY9MSiDuUjA9+Q==" indextimeout="600" indexdirectory="C:\Program Files (x86)\Metalogix\MAMSearch\Index\Mail_Legacy" />
</servers>
