Outlook is one amongst the most-used shopper applications by organizations round the globe. Workplace 365 is in high demand in several countries and there’s extensive excitement regarding running the most recent version of Outlook, that is Outlook 2019. However amid the thrill, there’s frustration: several area unit battling Outlook property problems. This downside not solely affects shoppers connecting to the cloud however all customers United Nations agency area unit still running on-premises versions of Exchange like Exchange 2010 or higher. What’s inflicting these Outlook property issues? It will be anybody of the following:

  • Lack of information measure
  • Older Outlook shoppers
  • Migrations gone wrong
  • SCP records not cleansed up
  • DNS problems or stale records or double Auto discover records
  • Firewall problems
  • Antivirus problems

Let’s take a glance at each of the things listed higher than and refer them — and if you’re having a haul, hopefully, we will get you up and running.

Bandwidth and Outlook property:

Speed may be a massive issue for Outlook shoppers as they’re sensitive to network blips or slowness. Imagine being on a 1MB ADSL line with twenty individuals making an attempt to attach. This may cause plenty of frustration, not solely connecting to workplace 365 however additionally to a datacenter wherever mail is hosted. In some countries, information measure is incredibly overpriced and corporations pay a fortune to induce sensible quality lines. That successively means that a lot of prices to use QOS (quality of service) so the end-user incorporates a nice expertise on Outlook, as in some firms the SLA for email is incredibly high.

Older Outlook shoppers:

With the newer versions of Outlook comes newer licensing prices and accumulated prices for purchasing the appliance. Firms tend to stay with the bequest shoppers and not upgrade quickly thanks to the accumulated value of code. Older shoppers like workplace 2010, which can have support ending in Gregorian calendar month 2020, area unit about to force firms to upgrade to newer versions of Exchange as a result of workplace 365 won’t support these older versions. The older shoppers additionally use RPC of protocol that is that the older protocol and newer shoppers and Exchange use MAPI over protocol to attach.

Ensure that your shoppers area unit up-to-date and patched. Missing patches can even cause disconnect within the older shoppers and you must follow what Microsoft sets out. Associate degree example would be to own a particular hotfix associate degreed patch loaded to confirm optimum shopper property to either an on-premises resolution or workplace 365. And take care to stay a watch on the support pages for each as Microsoft will update them.

Migrations gone wrong:

Sometimes you’re employed with ISPs and migrations for shoppers don’t forever go as planned. This could result to DNS records not being modified (more on this below) or as a result of Outlook shoppers have eaten knowledge however it’s taking terribly long that the Outlook shopper is slow or the backfill ne’er completes thanks to value or licenses running out for migrations. Take care to create your shoppers responsive to the value for migrations and additionally do staged migrations so shoppers don’t expertise the slowness. If potential, do them over a weekend once it’s quiet.

DNS records:

This is forever a giant downside once it involves shopper property. Outlook shoppers can question internal 1st before they’re going external. If you have got migrated your on-premises Exchange to workplace 365 or whole of alternative, take care to wash up the records you have got not solely internally however additionally outwardly. This ensures that shoppers don’t attempt to question the incorrect factor and find you with popups or being disconnected.


Sometimes once shoppers migrate from associate degree ISP to a hosted company or from associate degree ISP to workplace 365, there’s that Auto discover record that tends to linger behind and cause problems.

Firewall problems:

Almost all shoppers area unit running some type of a firewall. This could be a bequest TMG resolution or associate degree F5 load balancer acting just like the firewall or SonicWALL, and generally they’re not designed properly. This suggests not all ports area unit open for shopper property or the firewall has not been updated to regulate for the newer versions of Exchange on-premises or connecting to workplace 365.

Be sure to stay your firewall updated to support the newer versions and keep the foundations on the firewall clean thus you don’t run into any problems.

Antivirus problems and Outlook property:

An antivirus is nice keep the dangerous out, however generally the merchandise, if not designed properly, will cause a lot of problems to associate degree Outlook shopper than not having it. Totally different symptoms may be that mail is distributed to the incorrect folder because it is flagged incorrectly or Outlook is disconnected because the antivirus blocks all communication. You wish to create positive that you just piece the antivirus product properly as per the seller to confirm that end-users don’t find yourself with a lot of hassles. There also are applications that you just will use to troubleshoot shopper property. Let’s take a glance at a number of those.

Applications for troubleshooting Outlook property:

  • Fiddler
  • WireShark
  • Microsoft take a look at property web site

Fiddler may be a useful gizmo if you wish to deep-dive into associate degree Outlook that won’t connect. However a word of caution: This tool displays the small print in plain text and may be accustomed “sniff” traffic.

Wireshark can capture network traffic. Generally you have got a far off branch that routers don’t shrewdness to induce out or a network modification was done and traffic isn’t flowing because it ought to. This tool is nice for seeing however traffic flows on the interior network.
