We have the same problem with multiple of our customers.

Problem:

Each user needs to see multiple shared calenders.
We can add them without a problem, but it turns outlook 2011 in a real nightmare, slow responds and crashes.
If we remove the shared calenders, the problem is fixed and outlook works fast again.

We have this problem since we migrated from an onsite exchange 2003 to Office365 and Outlook2011, with the onsite exchange there was no problem.
It works perfectly on windows7 with office 2010 but all the Mac computers with outlook2011 are working so slow they constantly crash.

Is there some way to solve this, seems to me that calendar sharing is a basic function.

The Mac machines all have 8 GB of RAM and an up to date office2011.


I hope anyone can help.

Thx

I'm running Microsoft Outlook for Mac 2011, Version 14.2.2 (120421) on Mac OS X, Version 10.6.8, build 10K549.  My "$HOME/Documents" directory is a symbolic link to a directory on an external NAS, accessed by NFS.

I observed that e-mail search functionality doesn't work, and the reason appears to be that Spotlight refuses to index this volume:

$ sudo mdutil -i on /Volumes/MyNFSMountPoint
Password:
/Volumes/MyNFSMountPoint:
Error: unable to perform operation.  (-100)
No index.

For the sake of reliability, I am very reluctant to move "$HOME/Documents" directory to, say, my local drive.  (My NAS is protected by RAID and is backed up regularly.  Moving critical data off of the NAS would complicate matters considerably.)  By the way, it's perfectly fine with me if exactly one host--the computer on which I'm running Microsoft Outlook--is responsible for indexing the drive.  In other words, I don't require or expect multiple Mac OS X hosts to be able to use Spotlight with this volume--just the one that is running Outlook.

Having one's e-mail in a network-mounted directory is an entirely reasonable use case, so I'm wondering:

1. Perhaps I've misconfigured my NFS server or the NFS client settings in Mac OS X, and with a tweak or two, Spotlight can be made to start indexing this internal drive.
2. Perhaps Microsoft offers an alternative way, that does not depend on Spotlight, to index and search through one's e-mail.
3. If neither #1 nor #2 is the case, how can I contact Microsoft to request that they add this feature to a subsequent release of Outlook?  Whether the deficiency is in Spotlight, Darwin, Mac OS X, or Microsoft Outlook, Outlook really ought to be able to cope with such a use case as this.  Not being able to search e-mail on a network-mounted volume is unacceptable.

Where do I go from here?
Fresh in stall of Outlook for Mac 2011 (fresh install of OSX).  All updates have been applied to both OSX and Office.  When I go into Outlook, edit the accounts and either click on the 'E-mail Account' button or click the '+' then e-mail account nothing happens.  No dialog to add an e-mail account, no error, nothing.  Additionally, I have to force quit Outlook and re-launch.  I've tried to reboot and check the disk to no avail.  The only thin I haven't tried is de-installing/re-installing Office.

OSX 10.7.4
Office for Mac 2011 (14.1.0)
Outlook is syncing old mails and creating duplicates showing them in inbox as if they arrived today. This has happen twice now, today it rr synchronised  2000 old emails and showed them as received with todays date. Is this know bug, how can I resolve?
I have new a mac and have install outlook. But now I can only get e-mails and not send them! What can I do? It tells me, that my server isn't secure.
The mac book air is new. Some contacts were synced but then disappeared in my efforts to synch the calendar. Email synchs just fine. 
Am taking a punt that this might be an appropriate forum!

Why is it that until last week I could receive my Outlook emails simultaneously on my iMac, my MacBook Pro and my HTC Wildfire phone. Now I only get them to my iMac apart from occasional receipts on my other 2 devices. My Netgear Router settings have not been changed and my email account settings have not apparently been altered either. I can send emails no problem at all - except on my phone - but that's another matter!!

Grateful for any steers from anyone please.
Since a few days I'm experiencing the "micro-freezes" with Mac's spinning wheel in Outlook, and it is making it almost unusable.
Every few minutes, Outlook completely hangs and displays the spinning wheel for 3-4 seconds, during which anyway it buffers what I'm typing or clicking.
The issue does not happen when "Work Offline" is selected.

It worked quite well for about 6 months. Other colleagues had the same issue after a similar amout of time and switched to mail.app.

I am only using an Exchange account, over https. No pop, no imap.

I've read somewhere about problems with signatures, and I've tried to disable it: no changes.
I've disabled any Sync Service in Outlook: no changes.
I've rebuild Outlook's database: no changes.
I've looked at Wireshark while Outlook was running and didn't noticed anything strange before or after the freezes. Outlook's network activity stops during the freeze.
Outlook's Progress window doesn't show anything before, during or after the freezes.
I've enabled Outlook's Error Logs: nothing is shown.

Did anybody manage to solve the problem, or everybody just switched to mail.app?

I'll try to create a new Identity and start from scratch with it; I'm also going to try and switch from https to http. After that, I'll move to mail.app.

Thanks!
