Exchange 2013 mailbox migration stuck syncing StalledDueToCI
So I’ve just completed an Exchange 2007 to Exchange 2013 mailbox migration and to be fair the majority of it went smoothly but it wasn’t without a few bumps along the way which I would like to share with you and what I did to get them resolved. First off,…
Hidden folder – Greyed out attribute
Simple little one this for some reason a clients main Data folder was Hidden, no idea why but some people were obviously complaining that they couldn’t see the folder. Looking at the folder properties the “Hidden” attribute was greyed out. Because of this we need to change it using a…

Ah isn’t replication fun fun fun. While overcoming a replication issue the Group Policy Objects got corrupted, fortunately there were only a few which could be created again easily but you can’t delete the “Default Domain Policy” nor the “Default Domain Controller Policy”.

Windows Backup EFI System Partition error

Windows Server Backup to multiple disks
After a mammoth task of going through various customers backups I’ve concluded that the Windows Server Backup included in Windows Server 2008 onwards is actually pretty good. Ok so it’s a little limited in features but if you’re looking for a complete backup of your server then this tends to…
Mapi session exceeded the maximum of 500 objects
I got a call the other day saying that a particular mailbox was having some strange problems, disconnecting etc, however I knew that this was particularly large (25Gb) and is also shared. Jumping into good old ‘eventvwr’ I saw and saw this error dotted about: Error: MSExchangeIS EventID 9646: Mapi…

Normally a simple task of installing a certificate for IIS and Exchange 2010, however on this occasion once I’d imported the crt file into the Certificate mmc, I couldn’t then export it as a pfx certificate which Exchange 2010 requires for it to be ; As you can see all…
GFI MailEssentials Log limit
While configuring GFI Mail Essentials for a client I soon realised that there is a 40,000 email limit in the historical logs. While I’m sure this has been set for performance reasons I happen to be using a beast of a server and so looked into increasing this. The main…
