Blocking access from personal devices

≫ Next: Outlook 2013 View Settings Change

For risk management and confidentiality we are trying to enforce a policy that does not allow access to corporate email accounts on our Exchange 2013 from personal devices or those devices that are not managed by our BES12 server. It seems our users have found the "Cloud Magic" app for iOS and Android devices which allows them to connect to our Exchange server and access their email, calendar and contacts, contrary to our policy. I'm trying to figure out a way to block any device access unless they are attached to our BES server. In Exchange I can only find a way to block types of devices, which won't work for this need. I basically want to allow certain users access (those I know have corporately managed devices) to connect.

I've tried disabling everything on the user's account Exchange Active Sync, OWA for devices, Outlook Web App, IMAP, POP3, MAPI and I can still connect using Cloud Magic.

I do still need them to be able to uses Outlook Web Access from a browser though as well.

Any thoughts are appreciated.

The view settings on Outlook 2013 are changing for various users. Normally, when unread, the Header Text is blue and the first line preview is gray. Now for some users the Header and the first line are both blue for unread, but the first line remains blue after reading the email. On some folders I can reset the view but most folders have the reset grayed out. The only way I've found to reset everything is the /cleanview switch. I would like to know why this is happening and a better way to fix it than going to each computer and resetting with the /cleanview switch.

Hello everyone. I have a real head scratcher. W have an in house Exchange 2013 server installed on Windows 2012 Standard server. The client side is Windows 7 Pro with Office 2010 installed. The antivirus is AVG 2015 Business Edition and we have GFI Webmonitor installed on the network and GFI Mail Essentials on the Exchange Server. The only change we made to the network is 2 weeks ago we upgraded the GFI Webmonitor. Now to the problem. A week ago one or 2 client started getting the pop-up " Connection to Microsoft Exchange server has been lost. Outlook will restore the connection when possible" then the message "Connection to Microsoft Exchanged restored" This repeats itself every 15-20 seconds. I can ping the server by name and IP address with no packet loss. On the client side I have an event viewer error in the application log "Event 26 Connection to Microsoft Exchange server has been lost. Outlook will restore the connection when possible". no errors in the Exchange Server Logs. I have reset the TCPIP time outs on the client side with no improvement. Now gradually more and more of the clients are experiencing the same pop-ups. Trying to research this problem online is turning up a lot of irrelevant data. Any help would be greatly appreciated.

P.S. This condition does affect the mail flow between the client and server nor the server and the outside world. I have performed a continuous ping to the Exchange Server from the client when the disconnects are happening and there are no dropped packets.

Thanks George.

Exchange 2013 Mailbox Migration, Outlook 2010 Woes

≪ Previous: External mail from a different sender changed to a internal name while received

Hi, I'm in the process of deploying Exchange 2013. Most appears to have gone to plan but I'm having issues when migrating a mailbox to an Exchange 2013 database when the client is using Outlook 2010 (99% of our users are on Outlook 2010!).

I'll post a few screenshots below to try and explain the problem.

Firstly a 2013 mailbox on Outlook 2013 appears to connect correctly:

If I migrate a mailbox of a user with Outlook 2010 I get the following error message on startup and a partial connect in the status window:

After several weeks searching on this issue I did find that adding the follow registry entry would work:

[HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider]
"DS Server"="<LOCAL GC SERVER>"

Unfortunately this fix only works internally, externally it obviously can't find the GC server.

I thought this would point to a potential DNS issue? But seems odd that it's the global catalog server it's struggling to find. I've done various network lookups and the servers are returned as expected.

Also, if I remove the registry key above and try to recreate the account I get the following:

Adding the key back in and it'll discover the account and set it up with no problems!

I'm also puzzled by the certificate warnings. I've looked everywhere on the Exchange 2013 servers and can't see any self signed certificates being used. We have a GoDaddy SAN certificate and all the relevant names are present.

Using Get-OutlookProvider command no hostname, etc is listed. I'm reluctant to add anything in here as our 2010 and 2013 hostname differ.

I'm really struggling to think of anything else to try and fear I'm probably making it worse by constantly adjusting settings all over the place to try and resolve it.

At present OWA, ActiveSync and ECP is working fine for both 2010 and 2013 mailboxes (2013 is routing correctly), it's just Outlook that's having problems. Unfortunately it will be a while before our company moves to Outlook 2013.

I would appreciate any help you can offer!

Earlier today, we added cerificates to our exchange servers and change the outlook providers using set-outlookprovider. After doing so, outlook clients were not able to connect and received an error related to the certificate. The only way we have found to connect them is to delete the mail profile and recreate it. It there an easy way to force all of the profiles to recreate? Will the autodiscover cache refresh after some time?

Hi all,

some of our users are experiencing issue with missing presence icon on the left side:

They do not see this icon, only user name. Presence is working fine if we hover over the name and contact card shows up. In OWA it is also working as expected.

Tried both Outlook 2013 and 2016 with same issue. Disabled and also enabled hardware acceleration without any help.

If same account is logged in on another pc, it works fine so it is local issue.

I suspect it is because the issue pc has 4k monitor, we tried different DPI and screen resolution without any help. Even external monitor in difference size has this issue.

Tried GFX driver from pc manufactor, Windows update and also GFX provider without any help.

Seems like this is a known issue from earlier client:

https://support.microsoft.com/en-us/kb/2726007

This registry did not help since path shown in the link does not exist. (Common\PersonaMenu and Common\IM).

Does anyone have a workaround for this?

Computer is brand new and it is an annoying bug, since our users have to hover to see their presence.

Thanks!

Exchange Server Online, but computers not always able to connect

≫ Next: Emails in Outlook hanging up in outbox for extended period of time when connected to Exchange 2013 CU3

≪ Previous: Presence icon missing in Outlook 2013 and 2016

I have what seems to be a unique issue... We have about 50 computers on our network, and anytime one of those computers is turned on, Outlook 2010 works wonderfully. As long as Outlook stays open, the computer can be on for a week or more and Outlook continues talking with the Exchange Server without any issues.

The problems start when a computer has been on for more than a day or so and somebody decides to exit Outlook. Once that has happened when trying to reopen Outlook it says "The server is unavailable.".

The computer with the issue is able to use OWA, can ping/tracert the Exchange Server, and has full network functionality otherwise (can even connect to the Exchange Server to move files), but absolutely will not work in Outlook. Trying to access the E-mail Accounts results in the same "The server is unavailable." error message. I can create an entirely new profile which seems to work, but once I try to open Outlook, same error message with either profile.

If I restart the computer, everything is back to working flawlessly.

This is happening on at least 10 different computers.

I am stumped, hopefully somebody can help with this.

≪ Previous: Exchange Server Online, but computers not always able to connect

I have been scratching my head over this problem for a while now and wanted to pose the question here to see if anyone else has experienced it.

We have a server running Exchange 2013 CU3. Our employees are located in several offices across the country, and connect to Exchange with Outlook using Outlook Anywhere (RPC over HTTP protocol). Occasionally, an employee will experience a condition where emails are stuck in the outbox for an extended period of time. The symptoms of the problem present as follows:

1. Employee sends an email

2. Email sits in outbox. At the same time, emails are not coming in to their inbox

3. If the employee waits approximately 20 minutes, the emails caught in the outbox will send and mail flow will resume normally.

4. Alternatively, the employee can close Outlook and reopen it, and mail flow will resume normally.

5. We have not yet observed the issue affecting OWA or ActiveSync with any of our iPhones or iPads.

We have confirmed this happening with Outlook 2013 and 2010. Initially we were getting complaints on this issue from only one of our locations, so we assumed it was some sort of issue with unreliable internet connection, but we have started getting reports from multiple locations now, so clearly that assumption was in error.

I wanted to ask here to see if anyone else has observed this behavior and, if so, what has been done to attempt to fix it?

We are thinking on migrating our mail server to Exchange but I was told that non windows IMAP clients are not notified by email if their email account is over quota. Only MAPI clients are notified.

Is this true?

If so, is it possible for a non windows client to configure MAPI? If not, is it possible to have an automated task on the server that runs a script that scans all the accounts to check if it is over quota and sends a warning email to the user?

Good morning. We have had 3 instances of this situation:

A user stopped receiving emails in the Outlook client at 9:27am on 10/21. When she logged in to OWA her inbox was completely empty, though she had emails in her subfolders and archive. The client still had emails in it. An agent at the service desk sent an email to the user, and it showed up in OWA. As soon as the client did a send/receive it disappeared from OWA. The service desk agent rebuilt her profile and copied over her inbox to the new profile and all the messages then showed up in OWA, and everything seems to functioning now.

It happened to 3 users at 3 different times.

Does anyone know what might have caused this?
