If you use Office 365, you should take care of data protection. Data loss tin crusade even more financial and reputation loss for your organization compared to the low performance of a SharePoint site. Read the white newspaper to learn how you can back up Office 365 information, what are the risks, and what shared responsibility is.

Why Is Part 365 Running Slow?

There are multiple factors that tin cause Office 365 ho-hum performance. The reasons can exist problems on a client's figurer (hardware and software), network or internet connection issues, and issues on Microsoft's side (software updates, issues in a datacenter).

Net Connection Issues

The master requirement for using Office 365 is an internet connection. You need an cyberspace connection with high bandwidth and low latency. When using Role 365 online applications in a spider web browser and working with files in the cloud, a slow internet connection with high latency causes lags and delays. These Office 365 bug are inconvenient when y'all want to open up a certificate or write changes to it, and can considerably slow down operations.

Fixing cyberspace connection problems affecting Office 365 performance

  • Check the configuration on your routers and firewalls. Make sure IP addresses, protocols, and file types needed to piece of work in Office 365 are non blocked.
  • Make sure your router and firewall don't stop long-term TCP connections if they are idle. Office 365 establishes a high number of longer-lasting network connections. Cheque TCP idle time settings. Outlook Online initiates such connections for proper work.

If traffic shaping is configured, make sure the cyberspace speed for clients is enough to work in Office 365. Network congestion reduces Office 365 performance. Traffic inspection software on routers also has a negative impact on performance.

  • Opt for a wired network over a wireless network connection. A wireless network connection tin can be unstable and have high latency. If y'all demand to apply a wireless connection, make sure that the betoken level is stiff plenty, and the channel is selected correctly and doesn't interfere with the same channel number of nearby Wi-Fi networks.
  • Accept into account the circular-trip time (RTT), which is the time it takes information to be sent from a sender to a destination host, plus the time needed to receive the acquittance dorsum to the original sender. This time depends on the distance, transmission medium, the number of hops (routers), and destination server response time.
  • Check whether your internet connection is reliable and is not interrupted. Lost packets have a negative touch on on Office 365 performance. The easiest way to bank check network latency and stability of your network connectedness for initial analysis is to ping Microsoft servers. It is recommended that yous have local internet egress at the user's location.
  • Brand certain DNS is configured and works correctly. Microsoft datacenters are distributed across the world. Local computers should be connected to the nearest Microsoft datacenter to reduce the round-trip time and improve the user experience. Proper DNS configuration helps you lot attain this. If your system has a circuitous structure with branches located in dissimilar countries or regions, configure local DNS servers at each branch location instead of using i central DNS server. Apply the same approach to configure routing for cyberspace access in branch offices.
  • Cheque TCP window scaling configuration. Office 365 uses the TCP/IP stack for connecting to Microsoft servers. Transport Control Protocol (TCP) is the protocol designed to rail how much data has been transmitted with the guarantee of information transmission (unlike UDP). TCP flags or flag bits in a TCP header are used to initiate connections, carry data, and close connections. In this example, we are interested in SYN (synchronization) and ACK (acquittance) flags.
    Note: How does a TCP connexion using SYN and ACK flags work?
    • SYN flags are used to initiate a connection. ACK flags are used to acknowledge that a TCP segment has been received successfully (confirm that the data has been received) by the recipient. A 3-way TCP handshake with SYN and ACK flags is used to establish TCP connections.
    • When yous start a new TCP connection, hosts employ a receive buffer where the data is temporarily stored until it is candy by an application. TCP windowing is when a sender sends ane or multiple TCP segments, and a recipient acknowledges receiving one or all of these segments. A recipient sends the acquittance information about how much data a sender can transmit earlier a recipient sends an acquittance. This number of TCP segments (with the carried data) sent before getting an acknowledgment is known every bit the window size. The TCP connection usually starts with a small window and afterward each successful acknowledgment, the window size increases.
    • Once an IP packet is dropped, the TCP window size is reduced dorsum to ane segment and begins to abound over again. If a receive buffer is total, the window size is set to 0 until the buffer is freed up.
    • The window size is originally a 16-bit value (65535 is the maximum equal decimal value), which is the size of a buffer in TCP headers. This 16-bit buffer fills in milliseconds, and and so the delay occurs because traffic cannot exist sent until the recipient sends an acknowledgment to the sender.

Nowadays, the 16-bit receive buffer and the appropriate maximum TCP window size can exist increased by using a scaling factor. If a recipient cannot process the receive buffer in time and yous notice delays, endeavour to increase the buffer. To investigate the consequence, you may demand to apply a network sniffer (traffic analyzer).

  • Check the TCP maximum segment size. This is the maximum amount of data that can exist carried in a TCP segment. TCP maximum segment size should non exist less than 1460 bytes for optimal functioning.
  • Y'all may need to upgrade your internet plan. For example, if you lot use 10-Mbit internet, transfer to 100-Mbit internet. In this case, y'all demand to contact your internet service provider (Internet access provider). It can assistance y'all gear up problems with Office 365. If y'all utilize ADSL cyberspace, keep in listen that the upload speed is much lower than the download speed due to ADSL's asymmetric working principle. It is meliorate to use cable cyberspace via twisted pair or cobweb optic cable. Read more about network topology types in our guide.
  • If you lot edit Give-and-take, Excel, and PowerPoint documents but don't collaborate with other users online, consider installing Role 365 applications on your computer instead of using browser versions of Part 365 online apps. Save files on a local disk on your computer instead of saving files in OneDrive in the Role 365 cloud. With this approach, yous won't need to apply an net connexion as much to work with Office 365 documents, and you can mitigate Office 365 issues related to network connections. Fifty-fifty if you shop documents in a shared folder accessed via the local expanse network, the time needed to read and write MS Office documents is increased.

Software Issues

Another category of issues that can cause Office 365 performance deposition has to practise with software. Software issues ordinarily occur on a client's computer. If you discover Office 365 tiresome performance, try to check software bug on your computer and fix the institute problems.

Fixing software problems affecting Office 365 operation

  • Use antivirus software. Viruses and malware tin consume CPU and memory resources for their malicious action and, equally a consequence, there won't be plenty hardware resources for the applications. In addition, ransomware can corrupt all information on your computer and other computers connected to your network.

Pro tip: Download our white newspaper and detect out how to protect your data against ransomware.

  • Computers infected with malware can generate parasitic traffic. You may need to check network traffic on a switch or router to notice the computer generating unwanted traffic.
  • Make sure your antivirus software is configured properly. Some antiviruses can eat as well many resources to bank check retention, network, and disk activity. Such behavior causes delays and performance degradation.
  • Consider using Function 365 Advanced Threat Protection and Exchange Online Protection to reduce the risks of beingness infected with malware and ransomware via Office 365 email.
  • Effort to close unused applications except for the web browser used for opening Part 365 online apps. Close other tabs in the browser and leave only tabs with opened Role 365 applications. Check whether these operations helped ready issues.
  • Disable add-ons and plugins in a spider web browser to bank check whether they have an impact on the operation of Office 365 online apps.
  • Remove unused applications from Windows startup configuration. They tin cause conflicts with Microsoft Function 365 applications.
  • Disable telemetry in Windows. Telemetry doesn't provide useful features just consumes system resources to collect and transport data to external hosts. It is always better to disable telemetry.

Hardware Bug

If recommendations from previous sections have not helped you set Microsoft Office 365 issues related to slow functioning, bank check your hardware.

Fixing hardware issues affecting Office 365 performance

  • Make certain the hardware of your computer meets Office 365 minimum requirements. Y'all can check organisation requirements on the Microsoft website.
  • Check whether your deejay drive is healthy. Bad blocks and blocks with high admission fourth dimension on a hard disk drive cause performance degradation and risk of information loss. Run the S.K.A.R.T. data test to identify deejay problems and run disk surface tests if needed. Ensure in that location is plenty gratis disk space on your organisation disk and the deejay on which your browser and Function 365 applications are installed.
  • Check whether the corporeality of RAM (Random Access Memory) is plenty on your computer and there is plenty free retention. If there is non enough memory, the Os and application performance degrades significantly. An operating arrangement uses the bandy file to perform many read/write operations when at that place is no free memory.

Note: Organization monitoring tin can help you react rapidly and avoid hardware issues causing depression performance and possible data loss.

Why Is Outlook Running Tiresome?

In this section, we are going to explicate how to speed upwardly Outlook. If y'all use a standalone version of Office 365 Outlook installed on your figurer, and notice significant performance issues, try to perform the deportment explained below.

Symptoms:

Email folders such as Inbox, Sent, Junk emails, etc. are dull to open. If in that location are no internet connection issues for data synchronization in the email client, you may exceed the number of items per folder in 1 of these email folders. A similar issue may happen with a Agenda that doesn't display the most recent items.

Solution:

Try to perform these actions to prepare the issue when Outlook is deadening to open.

  • Delete items from the appropriate e-mail folders.
  • Configure Office 365 retentiveness policies and set how long items must be stored.
  • Enable the Commutation Online Archive Mailbox and configure email archiving to save space in your mailbox folders.
  • Change the number of months for which data is synchronized for shared calendars in Sync Windows Setting.
  • Update the installed Outlook awarding.

How to Fix SharePoint Operation Issues

  • Use a complimentary SharePoint Page diagnostics add-on for Google Chrome to check issues of website pages in SharePoint. This diagnostics tool tin can help you identify performance issues and factors that negatively impact performance.
  • Reduce image resolution and compress images when possible earlier uploading them on the spider web pages of your SharePoint site. Large images tin tiresome downwardly site performance and consume more than internet traffic to load. Loading heavy images takes more time.
  • Use the modernistic SharePoint interface instead of using the classic one. The mod interface is better optimized for large sites to meet today'due south requirements.
  • Information technology is recommended that you don't apply too many web parts on a single SharePoint web folio. Using too many parts causes performance degradation of a spider web page on a SharePoint site. If yous use iFrames to display external content, don't use too many (the recommendation is three or less).

Pro tip: Support SharePoint Online data to have the power to restore information in instance of unexpected SharePoint Online issues.

Fixing Microsoft Word and Excel Running Slow Issues
