Mailbox Size - Unity 4.0.4 with Failover (Exchange)

Answered Question

Hello,


I remember being told by TAC that once a mailbox store reaches 100MB it could start acting abnormally, (bouncing messages, playing incorrect order, etc). Does anyone have any insight or know where I can find documentation regarding this?


Thanks!

Just to set everyone straight here, the reference is 100mb for a mailbox not a mailbox store. And 1000 messages. This was in Unity 4.0(3) was the last doc that I saw it in.


Section D explains that Unified Messaging subscribers should not have Inboxes that exceed

100 MB or 1,000 messages. This is a copy and paste from

Assuming you mean 100GB, and you are referring to Enterprise Edition (standard has a much smaller maximum DB size), it still sounds like "Hogwash" to me.


We have several Exchange mail stores exceeding 100GB and they function perfectly well with no errors.


Any evidence you find will be anecdotal at best - Microsoft's official guidance is that the maximum store size, again with Enterprise edition, is "limited only by available hardware, with a theoretical maximum size of 16 terabytes." (http://technet.microsoft.com/en-us/library/b3aac217-5bb6-45ec-a8a6-2006c8335dbe.aspx)


I hope that helps you!

100Mb would be a very small mailbox store. Exchange is capable of handling stores much larger than this. I'm not aware of any size limit imposed by Unity. Exchange 2003 limits the size of the store to 75Gb in the Standard Edition and 8Tb in the Enterprise Edition.

That is exactly what i'm looking for, thanks rip! Also, I meant to say mailbox size, not mailstore size.
