O365 - Veeam Explorer for Microsft Exchange Very Slow

[paulrogero]

Hello,

I am using the Veeam Explorer for Microsoft Exchange to browse and search for emails. For instance, I just ran a search on my inbox that is still searching for emails.Its been a few minutes and it is still looking. Is this normal for searches to take many minutes?

I'm not sure what the percent indicator and time remaining tell me on the status bar in the lower right status bar but those are currently at 4% and 3 hours, 9 minutes.

I am on 8.1.3503.

Server has 16 vCPU with about 15-20% utilization at the moment, memory is at 31.9/48GB.

Thanks,
Paul

8.1 is not the latest version. what technology are you using for your repository? JET or object?

When I check for updates in the application, it says I am up to date. I will try to download an update for O365 backup manually instead. Veeam Explorer is at version 12.3.0.310.

In any case, the search has been slow for as long as I can remember going back a few years so I imagine the latest patch release will exhibit similar behavior.

I'm more wondering if this is expected behavior. Is there some configuration option I might be missing that is preventing searches from being relatively instant where they complete in a few seconds or less? My last search in Veeam Explorer took about 3 hours. I compared against an SMB Synology device doing O365 backups and it would return results in less than 1 second so I figure I must have something not set up right in Veeam.

I am using a local disk repository and not object-based storage.

I can dig into this more deeply with technical support but figured I would ask if my experience is unexpected. If you tell me that searches take many minutes to hours and should not complete in a few seconds then I won't bother opening a case.

Thanks,
Paul

Hi Paul

Its possible that the most recent version is not yet enabled on our update server. We normally wait a few weeks before doing the change on the update server. But you can find the most recent version in this KB: https://www.veeam.com/kb4106

For the search performance, I recommend to open a support case.
I don‘t expect results in seconds, but taking minutes or 3 hours seems wrong. Please let us know the case number if you open a case.

Best,
Fabian

maybe your setup is too slow. or you forgot to set av excludes kb3074
a Veeam support case will tell

I have a case open with support but that has not yielded any information, yet. Case# 07676851

I do have the directories in that KB excluded from antivirus. When I run a search, the server is mostly idle. CPU usage is often sitting around 20%, memory usage is around 20%, and disk utilization is around 0%. No part of the computer seems to be under any load that would delay search results.

In most search programs, there is an inverted index, or some other type of index, that allows the program to satisfy search queries quickly. My cheap Synology must use an inverted index because I can search the same mailbox in its Office365 backup product and the search results come back in seconds. When I search in Veeam, it takes a very long time, many, many minutes just to return emails from a couple months ago. Searching the entire mailbox takes an hour.

Another example is Outlook itself. I feel like 15 years ago in Outlook 2010 there was not a search index and any search took a while because the program would literally search through every email to see if it contained the text in the query. Every search meant loading every email in your mailbox into memory and reading the entire contents. Modern Outlook builds an index so that when you search it can return results instantly.
