Outlook 2010 generating "There is not enough free memory to run this program" error

Interesting one this.

When I allow a user to see the MD's Exchange mail box (cirxca 12GB) she starts to get the error message:

 "There is not enough free memory to run this program. Quit one or more programs, and then try again."

What is odd is that F9/Send+Receive and auto e-mail updates no longer work and you have to manually press the Update option to receive mail.

The machine has 4GB memory of which 2.5GB is free. The same phenomenon happens in "outlook.exe/safe" mode.

I have tried this on two machines and when you add in the second Mailbox this problem begins.

Both the manager and delegates are using the same Outlook build to access the mailboxes?

Its a general recommendation that the manager & Delegates should be using the same closest possible builds of Outlook client-version?

If she doesn't have access to the additioanl l;arge mailbox then it's fine.

Sorry that got posted too quickly. When I manually list the server I get:

ExRCA is testing Exchange ActiveSync.
The Exchange ActiveSync test failed.
Test Steps
Attempting to resolve the host name remote.hasted.com in DNS.
The host name resolved successfully.
Additional Details
Testing TCP port 443 on host remote.hasted.com to ensure it's listening and open.
The port was opened successfully.
Testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
Test Steps
ExRCA is attempting to obtain the SSL certificate from remote server remote.hasted.com on port 443.
ExRCA wasn't able to obtain the remote SSL certificate.
Additional Details
The certificate couldn't be validated because SSL negotiation wasn't successful. This could have occurred as a result of a network error or because of a problem with the certificate installation.

I was under the impression that the Outlook machine is throwing the following error\warning:
 "There is not enough free memory to run this program. Quit one or more programs, and then try again."


In this case, Outlook is trying to connect and communicate with the mailbox...not trying to access Autodiscover

Apologies - got two EE issues muddled up. Forget my last two posts.

Both outlooks are on the same version.

Check that Office 2010 SP1 is installed
http://support.microsoft.com/kb/2460049

There were several Memory Issues addressed in this SP.

Check that Cached Exchange Mode is not on.
This will prevent the emails being copied to an .OST as the mailbox is being opened

I presume that this is on the workstation? The server is on Exchange SP1 and I intend to upgrade it to SP3 when I have got all rogues issues like this sorted out.

I upgraded the service pack but the solution was to the turn the "Used Chached Exchange Mode" off.

Any ideas why Outlook couldn't cope with this....

AH okay.

Depends on how big the Mailbox was and how old the .ost file was.

If an Older ost it would have had a miximum size of 2gb.

If a newone was created in 2010 it shoudl have a maximum size of 20gb.

So if the users Inbox is anywhere around these size limits, you could have had issues.

Another this that would have caused this is if the ost is not stored on the local drive but somewhere on a shared network location.
Coupled with a large inbox there could have been some latency issues.


And this is probably not the case, but if it is stored on the local PC. However, if the local PC was low on disk space it could cause issues with a ost file that needs to grow

From memory the one she aded was around 13GB. Her's was circa 3GB.
Is there an issue with the total combined that Outlook can see at any time?

We tried it on a couple of "local" machines. One old, two core, and the other 4 months old with four. Both behaved identically. The latter had 4GB RAM of which 1.5GB was beign used.
